ZyXEL To Ship 500 Mbps Powerline Switch | SmallNetBuilder

From the horse’s mouth

Zyxel press release

My Comments

Gigabit Ethernet is now becoming the order of the day with most current desktop and laptop PCs as well as network-attached-storage units being equipped with such a port. This is being taken further with routers having to be equipped with Gigabit Ethernet LAN (and WAN) ports in order to be considered fit for next-generation broadband Internet. This situation is also augmented with basic 5-port and 8-port Gigabit Ethernet switches now becoming more affordable.

At the moment, most HomePlug AV-Ethernet switches have been equipped with Ethernet ports that can work to a link speed of 100Mbps. This wouldn’t work in an optimum manner if you are connecting Gigabit-Ethernet-equipped computers to a HomePlug AV segment.

What Zyxel have done now is that they have announced a HomePlug AV Ethernet switch, the PLA4225, that uses Gigabit Ethernet ports as well as working to the unqualified 500Gbps extension of the HomePlug standard. This could allow you to provide a proper high-throughput HomePlug AV on-ramp for your desktop or laptop computer; fully-compliant next-generation-broadband “edge” router and NAS with these devices working at speed.

This is also in conjunction with them releasing the PLA4205 “homeplug” that works to the same powerline-network standard but uses a single Gigabit Ethernet socket.

Personally, what I would like to see for all of these 500Gbps HomePlug AV devices is that they are able to work to the full HomePlug AV2 standard once it is ratified and a proper firmware update is delivered.

But what I am pleased about is that the Ethernet connectivity of this HomePlug hardware is up to standard for people who use next-generation broadband Internet services with the proper routers.

Firmware modders keep legal storm brewing

My comments

There is an increasing trend to design devices as though they are a computer similinar to a regular desktop computer. Here, the operating software for these devices, commonly known as “firmware”, is designed so it can be updated in the location where the device is used.

Typically newer versions of this software are delivered over the Internet, most likely via the manufacturer’s Web site or, in some cases, through device-support forums.

Methods

One common way of delivering this software is to deliver the update as a binary package that you download using your regular computer, then upload to the device in one or more different ways.

This may involve physically transferring the package to the device using removable media which you install in the device. Then you may either restart the device or select a “Firmware Update” menu option to load this software in the device. An example of this may be a digital camera or an MP3 player.

It may also include uploading the software to the device’s Web management interface as is commonly done with wireless routers. On the other hand you may have to run a firmware-update program on your regular computer which delivers the software to your directly-connected device such as a printer or, in some cases, your network-connected device.

An increasingly-common method that is used for devices that are connected to the Internet is to invoke a firmware-update routine through the setup menu. Here, the device visits a special server run by its manufacturer, checks the version of the firmware on that server and downloads the latest version if it exists on that server. This may be performed as part of the setup routine for a new device or the device may poll the server for new firmware updates at specified times.

Benefits

The main benefit from device firmware that is updated through the device’s lifespan is that there is a chance for the device’s manufacturer to “iron out” bugs that may have been overlooked in the haste to get the device to market as soon as possible. This also includes “tuning” the device’s performance at handling particular tasks as newer algorithms come along.

In some cases, a firmware update may be about improving security, which is part of the increasingly-common “cat and mouse” game between the device manufacturer and the device-modding community. It also is about adding extra functions to the device that it didn’t come with when it was launched. An example of this include Draytek adding 3G wireless-broadband WAN functionality to their VPN routers or supporting newer wireless-broadband modems on these routers.

The field-updatable firmware packages can allow a device to enjoy a longer service life as newer requirements can be “baked” in to the software and rapidly pushed out to customers. Examples of this can include support for newer peripheral hardware or newer operating standards.

Drawbacks

There may be cases where some functions offered by the device may be broken due to a firmware update; or the device’s user has to learn new operating procedures to perform some of the functions.

As well, firmware updates that are drawn down by the device may chew up bandwidth especially if there are more of the same device to be update. This can also extend to frequently-delivered large firmware updates for the same device.

Experiences

One situation that I had observed was the use of a Creative Labs Nomad Jukebox as a music-playout device at the church I go to. Initially, there were problems with using this music play because the previous music-playout device, which was a MiniDisc deck had a time-remaining indicator for the currently-playing track.

Subsequent to the purchase of this music player, Creative Labs delivered a major firmware update across the Nomad Jukebox range and this firmware had a “fuel-gauge” indicator to show how far in to the currently-playing track the unit was as well as a time-remaining indicator. Once the latest firmware was applied to this Nomad Jukebox, it became easier to use the device for the purpose that the church bought it for.

Another example was the Western Digital WDTV Live network media adaptor. Through the time I had the unit, there had been many firmware updates with UPnP AV / DLNA media playback being delivered through one of the updates and full MediaRenderer functionality being delivered at a subsequent update. Similarly, this device acquired Facebook, TuneIn Internet radio and other network-service functionality.

Yet another example was where I reviewed two HP business laser printers for this site. I had noticed that once these printers received firmware updates, they were able to work with HP’s ePrint ecosystem.

Issues

A large software image for a small problem

One main issue with firmware updating is that the company typically needs to deliver a complete firmware image to fix a small problem in the device. This can be annoying as devices have a firmware size equivalent to earlier incarnations of the Windows operating environment and this figure is increasing rapidly.

A direction that may have to be looked at for firmware-update delivery is to implement practices associated with updating regular-computer operating systems. This is where smaller incremental updates are delivered to the device and installed by that device. Apple has headed in to that direction with the iOS and this has become easier for them due to the regular desktop computing system being their founding stone. This direction may not work if the firmware is to be subject to a major rewrite with a changed user-interface.

Making and breaking preferred content distribution mechanisms

The article looked at the issue of field-updatable device software as making or breaking a preferred content-distribution model. There are examples of this with games consoles having their software modified so they can play pirated, homebrew or grey-import games titles; the “jailbreaking” of iOS devices (iPhone, iPad, iPod Touch) so they run software not provided by the iTunes App Store; or DVD and Blu-Ray players modified to play pirated and grey-import movies.

The manufacturers are in a game of “cat and mouse” with these devices with the software-modification community to keep these preferred distribution mechanisms alive. This is especially with devices like printers or games consoles that may be sold at loss-leading prices so that customers buy software or accessories at higher prices through preferred distribution chains.

Limiting “out-of-the-box” functionality unless updates are performed

This can lead to devices and partner software being unable to function fully unless the device is updated.

Some examples of this may include the PlayStation 3 games console package cited in the original article where you needed to download a significant update to play a game that was packaged with the console. Then you had to download extra software on to the console from the game supplier before you could play online.

Another example would be the previously-mentioned HP LaserJet printers which needed to be updated before they could run with the ePrint ecosystem. This situation may happen if the new software requirement was ran out just after the hardware was released.

Update loops

A situation that can occur with devices that implement Internet-based updating is what I call an “update loop” or “update chain”. This is where the device completes many firmware-update cycles before it becomes useable. It has happened with the WDTV Live network media adaptor but can happen with other devices.

What manufacturers could do is to allow a “once and for all” update cycle that obtains and installs the latest firmware. The server software could prepare a software build that is particular to the device’s current firmware and supply that build rather than supplying earlier software builds.

PC-style functionality addition

The trend now is to have our devices work in a similar vein to a regular personal computer, where users can add accessory hardware and software at a later date through the product’s lifecycle.

This is intensified with the “app” ecosystem that has been driven by smartphones and tablets, where users visit an “app store” to download programs to their devices. Similarly, TV manufacturers are integrating programs like Skype in their network-enabled TVs and allowing customers to add on Webcams to these sets for video conferencing.

Here, we could the thinking of adding software functionality to devices either through apps and “drivers” that are downloaded as hardware is installed or subsequent full firmware updates. The former method could work well with devices that can have their functionality evolved by the customer or installer whereas the latter method would work with devices that perform the same function all the time.

What could be looked at with device software management

UPnP Device Management

The UPnP Forum have recently released a DeviceManagement Device Control Protocol which allows for network-based configuration and management of devices. This includes a SoftwareManagement Service which looks after the issue of software delivery for these devices.

This may be of relevance where another device works as a management point for another networked device with no user interface or a limited user interface. An example of this setup may be a regular computer or a tablet running an application that co-ordinates and manages firmware updates for a variety of devices; or an IPTV set-top box that is part of a “triple-play” setup managing the software on the router that is at the network-Internet “edge”.

Use of a network-attached storage to keep device software images

An increasing number of home networks are or will be equipped with a network-attached storage device which shares data held on a hard disk across the local network. One main application for this would be to keep music, picture and video files so that they can be shared across the network.

The industry could look at ways of using these NAS (network attached storage) to track down and keep a local cache of new firmware for devices on the home network. Then the devices can check this resource for newer software images when they need to update their firmware.  This may suit home networks where there are multiple devices running the same software, such as multiple units of the same games console or multiple TVs made by the same manufacturer within a close time frame.

It may sound like a practice associated with computing in the “big end of town” where the desire by business IT teams is to maintain standard operating environments; but this technique could be used to keep multiple devices from the same manufacturer up to date without using up bandwidth for firmware updates. As well, with the appropriate protocols, it could allow for a “hands-off” approach when adding new devices to the network or maintaining existing devices.

Conclusion

As more and more dedicated-purpose devices move towards the computing model used by regular computers, we will need to think of issues concerning keeping the software up to date and using the updates to improve the devices.

La Freebox Révolution est compatible avec AirPlay et Time Machine – DegroupNews.com

My Comments

It is not common for Internet-gateway equipment that is typically supplied by a communications provider or ISP to support any of the protocols that are peculiar to Apple’s ecosystem. Typically a person who wanted a device to work tightly with their Macintosh or iOS device had to use a network device supplied by Apple or an Apple-approved third-party vendor.

Increasingly most network-attached storage devices started to support iTunes server functionality or Apple Time Machine backup functionality through the use of open-source components that were enabled through the device’s Web-based dashboard. But the AirPlay playback function has been based on code that Apple controls and devices had to have Apple approval in order to compete with the Apple TV device as a media player.

Now Free, one of the telecommunications carriers in France’s lively and competitive “triple-play” Internet market have integrated their latest Freebox Révolution customer equipment with the Apple ecosystem. This functionality is supplied for free as part of the latest firmware update for the Freebox Révolution router and set-top box.

At the moment, the AirPlay playback functionality is available through the Freebox Server’s integrated speakers or an audio device connected to the Freebox Server’s line output. The Time Machine network backup is done by using the Freebox Server’s integrated hard disk.

There are some other slight improvements for the Freebox Player in the form of  improved MKV compatibility and UTF-8 subtitle handling. But this device could really support the AirPlay functionality better because it would ordinarily be hooked up to the TV and a good-quality home-theatre system. As well, if Apple allows, it could support AirPlay video playback from from a Macintosh computer or an iOS device.

It certainly shows how capable the consumer-premises equipment for a triple-play service can become under a highly-competitive environment for “triple-play”Internet.

Samsung to produce 7" high-res AMOLED display | SammyHub.com

Un écran tactile AMOLED 7″ à « forte » résolution chez Samsung | Le Journal du Geek

My comments

Samsung have been involved in developing the active-matrix OLED display over a long time and have refined it in to a single-layer AMOLED touchscreen display that is pitched at smartphones.

As you all will know, the difference between the OLED display and the LCD display is that the way the display is lit up. An OLED display uses power to actually light up the pixels rather than dynamically passing light through a filter that makes up the image, a practice that is done with LCDs.

There are some key benefits that these displays have such as high contrast, improved colour, a wide viewing angle as well as energy saving due to only needing to light up what is needed on the display. Infact I have described the OLED display as a “vacuum fluorescent display” for battery-operated devices because the displays have that same bright and crisp display characteristic as the vacuum-fluorescent displays used on a large range of good-quality consumer electronics like DVD players and home-theatre receivers.

For that matter, I currently own the Samsung Galaxy S Android smartphone which has this display technology and have been pleased with the way it handles regular display activity including pictures and videos. This is even after I have owned the Nokia N85 Symbian S60 smartphone which uses the same AMOLED display technology in a non-touchscreen application.

Now they have taken this technology further by developing the Super AMOLED Plus which is the same AMOLED display with integrated capacitive touchscreen as used in these Galaxy S series smartphones, but as a 7” 1024×768 variety.

At the moment, the obvious application for this display would be the 7” tablet but I would see it appeal to more applications such as dashboard touchscreens for the car or boat. This may also include the double-DIN multifunction head units that will appeal to the young males who want to equip their cars with street-worthy sound systems.

If Samsung wanted to have sufficient manufacture quantities for these displays as they do for the small OLED displays used in the smartphones, they would have to build one of their Galaxy Tab 7” tablets with these displays. This also includes encouraging other manufacturers to implement them in a 7” tablet model.

Who knows when it would be that Samsung would take the integrated touchscreen AMOLED display technology up to the 10” size for the larger tablets and netbooks.

It is also becoming very similar with Hewlett-Packard’s Photosmart and OfficeJet inkjet printer ranges where there are a few common mechanisms implemented in the products. But, in HP’s case, the different models have differing cosmetic designs so as to integrate different feature sets and make the more expensive machines look classier.

A lineup of models with varying feature sets and throughput speeds but with the same design

In the vehicle world, an example of this was Holden’s large family cars sold through the 1960s to the 1970s. These vehicles had different model names depending on their level of luxury and / or their powertrain, with the “Premier” representing the top-of-the-line standard-wheelbase vehicle. Low-end vehicles were referred to initially as “Standard” or “Belmont” vehicles until the early-70s “HQ” series while “step-up” or “mid-tier” vehicles had model names like “Special” or “Kingswood”. This was until the “HQ” series where vehicles in that and subsequent series had “package” suffixes to differentiate entry-level and mid-tier vehicles.

For example, I had noticed that the HL-2240D direct-connect duplex monochrome laser printer was part of a series of laser printers based around a new printer design and print engine. There was a low-end model known as the HL-2130 which couldn’t print both sides as well as the HL-2250DN which was equipped with Ethernet networking and the HL-2280DW being equipped with Wi-Fi networking. Similarly, the more expensive models in the lineups also benefit from higher page throughput due to more powerful components in the design.

A model range derived from another model range

But the practice becomes very similar to how the vehicle builders derive a model range design from another concurrently-running model range design. An example of this would be them designing a longer-wheelbase luxury “executive” car as a derivate of a standard large family car like what Ford have done when they derived the Fairlane and LTD designs from the Falcon designs.

Here, this is reflected in how the designs for this company’s laser-printer lineup are used. I had observed that the multifunction series including the MFC-7360N that I reviewed were derived from the previously-mentioned dedicated laser printer series that the HL-2240D was part of. Here, all the units in both printer lineups used the same print engine and the same replacement parts.

Benefits for product choice

This will allow for a granular range of products in a product class where a person can choose or specify the right kind of printer based on their needs and budget; without needing to create new designs in order to satisfy the different market segments. This also allows the manufacturer to keep product prices within affordable territory because there is the ability to reuse parts across the different models. It also can allow a salesman room to upsell customers to better products or make deals that offer better value.

In most cases, the mid-tier product will offer best value for most users. For example, in these two printer lineups, the mid-tier models (HL-2250DN dedicated printer and MFC-7460DN) will offer the two currently-desirable features – double-sided printing which saves paper; and network connectivity. In some other cases like the dedicated colour laser printers based on Brother’s latest high-throughput colour-laser print engine, the HL-4150CDN which just has Ethernet network connectivity and reduced-time-penalty colour duplex printing would suit most users.

Conclusion

The creation of a granular product range with incremental functionality but a few common design bases and /or descendent product classes can then allow manufacturers to keep consistent value for money when they want to build out a product range.

I know that a lot of Hewlett-Packard’s network-enabled printers in the Photosmart range like the Photosmart Premium Fax C309a support this functionality. This also includes the HP Envy 100 printer which I have just reviewed. Some other manufacturers like Epson may support this functionality in a few of their products.

The reason that there is inaction concerning the UPnP Printer device class is that there aren’t enough client devices that properly support this function. So far, some of the Nokia phones that work on the Symbian S60 Third Edition platform like the N95 and N85 can print photos to these printers using this platform. But I know of no other devices or platform apps that exploit this functionality.

Key enabler for this device class

Platform devices

An increasing number of manufacturers are moving towards the use of device platforms like Android and Maemo as the baseline operating system for embedded-platform devices like set-top boxes, PVRs and TVs as well as smartphones and tablet computers. These platforms typically use “apps” as a way of adding functions to the device, effectively turning the device into something that resembles a general-purpose computer. These “apps” are typically written by third-party developers and provided through an “app-store” or similar menu that is hosted on the device, either for a low cost or, in a lot of cases, for free.

These platforms, save for the Apple iOS platform, don’t have a printer-interface function that these apps could exploit and what is happening is that printer manufacturers are writing photo-printing apps for these platforms that work with their devices. They can support the UPnP Printer Device Class as a printing interface rather than reinventing the wheel for this function.

Key applications

Hardcopy from the tablet computer

As the tablet computer becomes increasingly popular amongst home and small-business users, there will be a requirement to turn out hard-copy from the apps loaded on these devices. Examples of this include printing emails or chapters from ebook apps to printing out photographs taken using the device’s integrated camera.

At the moment, the iPad can work with AirPrint-enabled printers like the HP Wireless-E B110a, the HP Envy 100 and the HP Colour LaserJet CM1415 that have been reviewed in this site. Windows 7 tablets can use the conventional driver-based Windows printing platform but Android and WebOS tablets don’t have an integrated printing platform. Access to the printers for these platforms is through photo-printing apps which are limited in purpose because they only print photos or, in some cases, PDF files; and are also tied to particular manufacturers’ printers.

If Google, HP or other companies who are behind tablet-computer and smartphone operating systems implement the UPnP Printer Device Class, they can add a driver-free printing ecosystem to these operating systems.

Hardcopy for Interactive TV

As the TV set becomes integrated with the Internet, there will be an interest in interactive TV. This will allow the viewer to interact with broadcast material using their remote control. Initially, it is being used with some broadcast-TV set-top boxes that use a cable-TV or dial-up-modem return path to facilitate purchasing of pay-per-view content or increasingly to allow viewers to register votes when they watch panel shows or talent quests. The Internet path is increasing the interactive TV abilities through the delivery of extra material to the viewer, thus permitting concepts like “catch-up TV” and on-demand availability of extended interviews and supplementary material. It is being augmented by set-top boxes, PVRs and TV sets (especially the main-lounge-area ones) being equipped with network connectivity.

The UPnP-enabled printer can work well with Interactive TV by offering a hard-copy option for editorial and advertising content. In the case of editorial content, this could lead to the availability of factsheets, end-of-show leaderboards and similar material.

The best example of this would be MasterChef, the popular cooking-based reality TV show. In a typical season, there are many recipes that will appeal to one’s tastebuds and may “fill in the gap” for a cooking situation that may be particular to one or more viewers. Here, the viewer would have to go to the MasterChef website using their computer and search through the recipes for the one that interests them in order to print out the hard copy they need to work from when they build their shopping list and when they cook the dish in the kitchen. It could be made easier by the viewer pressing a button on the Interactive TV remote control while the recipe is being cooked to have that recipe printed out, or obtain a recipe list for this current episode so they can choose what to print out.

Even the commercials could be augmented with “print-to-redeem” coupons, “specials lists”, factsheets and product-disclosure notices that the viewer can print out at the touch of a button when they see the ad. This can be extended to programs like game shows or talent quests that exploit viewer participation and use “print-to-redeem” coupons as incentives for viewers who participate in these shows.

Games and apps that are part of the interactive TV experience can be augmented with hardcopy options. Examples of this could be skill-based games that reward users with prizes for successful completion or being at the top of the game’s leaderboard; or apps that provide hardcopy information on demand.

Companies who are behind interactive-TV platforms like those involved with Internet TV could implement UPnP Printer Device Class in order to open up the possibilities offered with hard copy for Interactive TV.

Hardcopy snapshots from digital cameras and electronic picture frames

The UPnP Printer Device Class offers the ability for a connected electronic picture frame or digital camera to print snapshots through an existing home network rather than having to use “peripheral connections” like USB or Bluetooth.

This can avoid the need to locate a frame that receives “new” images via email or online services near the printer to print out the snapshots. Similarly, one could print out snapshots taken with a Wi-Fi enabled digital camera or mobile phone without worrying about whether the camera will work with the printer. This would be more acceptable for people who like creating “picture walls” from special events that they host. These “picture walls” are collections of pictures of the event taken by guests that are stuck to large sheets of cardboard.

Conclusion

But there are more applications like the ability to obtain a copy of a “dashboard” screen from a monitoring device through to “on-demand” news-printing from other devices. It also means that the UPnP Printer Device Class can open up paths for innovation when it comes to the functionality roadmap for a device targeted at a home or small-business user. As well, the UPnP Printer Device Class can also be useful as a “generic printer driver” for general-purpose computers so that basic text and graphics print jobs can be turned out without the need for awkward print drivers.

What needs to happen is that companies need to get serious about implementing this device class in their printers, computers and network-enabled devices.

Capabilities

This connector has a current raw transfer speed of 10Gbps but could have a theoretical maximum is 40Gbps (20Gbps up and 20Gbps down) when both pairs of wires are used. You can use this same “pipe” to pass a DisplayPort-based audio-video stream for a display as well as PCI-Express-based data stream.

There is the ability to daisy-chain 7 Thunderbolt-connected devices but you can have less than 3 metres between the devices at the moment.

Thunderbolt at the moment

This technology will complement USB and other connection technologies but will be like what happened with USB in the mid-90s. This means that it will be an Apple-only technology and this will appear on the latest run of MacBook Pro laptops.

It will appear on PC-based computers in early next year. As far as retrofit opportunities go, Intel had mentioned that it could be available for new motherboards but there was nothing much said about availability as an add-in expansion card.

The main peripheral applications would be external storage subsystems like the LaCie “Little Big Disk” storage array; as well as displays. Such peripherals that have this connection will typically be marketed as being “Thunderbolt-ready”.

What could it offer

Another storage-expansion connection for computing devices

One key application would be to provide a high-bandwidth direct connection between computer devices and one or more external hard-disk storage subsystems. The reason I use the term “computer devices” is because such devices could encompass PVRs which could benefit from capacity expansion, routers and network devices that convert attached external hard-disk subsystems to network-attached storage; as well as the general-purpose computers.

Multifunction devices that are fit for the new generation of compact high-performance computers

There is the possibility for one to exploit the Thunderbolt concept to design a multifunction desktop console unit. Here, this unit could house a screen, audio subsystem, video camera, removable storage such as an optical drive or SDXC card reader and/or a USB hub. Another variant could house a keyboard instead of a screen and connect to one or more external displays using DisplayPort or regular monitor connectors.

This display unit would be connected to an ultracompact system unit that has only the processor, RAM, graphics-processor, network connectivity and a hard disk, plus some USB sockets for a desktop application. On the other hand, this display could serve as a “desktop display” for a subnotebook or ultraportable computer. The USB hub would come in handy for connecting keyboards, mice, USB memory keys and similar devices.

Here, these multifunction devices can be designed so that they are no “second-class citizen” because they have multiple functions. This means they could render the multiple video streams as well as support the high-capacity removable storage technologies like Blu-Ray Disc or SDXC cards.

This is more so as the Intel Sandy Bridge technology makes it feasible for small computers like book-sized ultracompact desktops and notebooks of the “subnotebook” or “ultraportable” class to “have all the fruit” as far as performance goes.

Issues that may be of concern

One main issue that I would have about the Thunderbolt technology is that Intel could limit it to computer applications that are centred around its chipsets. This would make it harder for competing processor designers like AMD or NVidia to implement the technology in their chipset designs. It would also place the same implementation limits on system designers who want to use chipsets that offer improved performance or better value for money alongside Intel processors on their motherboards.

This is like the Intel Wireless Display technology which allows a special display adaptor to connect to an Intel-based laptop computer via a WiFi wireless network and show the pictures on the attached display device. Here, this functionality could only work with computers that have certain Intel chipsets and couldn’t be retroactively applied to older computers.

Another issue would be to encourage implementation in “embedded” and dedicated-purpuse devices like PVRs and routers as well as the general-purpose computers. For some applications like the previously-mentioned storage-expansion application, this could add value and longer service life to these devices.

Conclusion

Once the Thunderbolt technology is implemented in a competitive manner, it could open up a new class of devices and applications for the computing world by making proper use of the “big fat pipe” that it offers.

Network Infrastructure

Network Connectivity

Some newer chipsets have appeared which will increase network bandwidth for the 802.11n Wi-Fi segment and the HomePlug AV segment. The current implementations may use manufacturer-specific implementations which won’t bode well with the standards.

The first new “call” is the 450Mbps 802.11n WPA2 WPS Wi-Fi segment which is being provided by most network makes for their midrange routers and access points. Access points and routers that work with this specification use three 802.11n radio streams to maintain the high throughput. The full bandwidth may be achieved if the client device is equipped with an 802.11n wireless network adaptor that supports the three streams but your existing devices may benefit due to reduced contention for the wireless bandwidth due to the access point / router offering three streams.

Most of the routers shown at the Consumer Electronics Show this year that support the 3-stream 450Mbps level for the 802.11n wireless network functionality also offered dual-band dual-radio operation to the same specification. Here, these devices could work on both the 2.4GHz band and the 5GHz band at this level of performance.

Some manufacturers were trying out the idea of a 60GHz high-bandwidth media network which may be based on a Wi-Fi (802.11 technology) or other proprietary scheme. This could lead to three-band multimedia routers and access points that use 2.4GHz and 5GHz for regular whole-home wireless networking and 60GHz for same-room wireless networking.

The second new “call” is the 500Mbps throughput being made available on high-end HomePlug AV devices. These powerline network devices may only achieve the high bandwidth on a segment consisting of the high-bandwidth devices that are based on the same chipset. Here, I would wait for the HomePlug AV2 standard to be fully ratified before you chase the 500Mbps bandwidth on your HomePlug segment. Of course, these devices can work with HomePlug AV segments.

The third new call is for midrange high-throughput routers to have Gigabit on the WAN (Internet) port as well as the LAN ports. This is more relevant nowadays as fibre-based next-generation broadband services are rolled out in most countries.

Everyone who exhibited network-infrastructure equipment offered at least one 450Mbps dual-band dual-radio router with Gigabit Ethernet on the WAN (Internet) connection as well as the wired-LAN connection. As well, most of these routers are equipped with circuitry that supports QoS when streaming media and some of them have a USB file-server function which can also provide media files to the DLNA Home Media Network.

Trendnet also offered an access point and a wireless client bridge that worked to this new level of 802.11n performance. They also demonstrated power-saving circuitry for Wi-Fi client devices which throttles back transmission power if the device is in the presence of a strong access point signal for their network. This was ostensibly to be “green” when it comes to AC-powered devices but would yield more real benefit for devices that have to run on battery power.

They also ran with the TPL-410AP which is a HomePlug AV Wireless-N multi-function access point. Another of those HomePlug access points that can “fill in the gap” on a wireless network or extend the Wi-Fi network out to the garage, barn or old caravan.

They also issued the TEW-656BRG 3G Mobile Wireless N Router, which is an 802.11n “MiFi router” that is powered by USB and works with most 3G / 4G modem sticks available in the USA. It is of a small design that allows it to be clipped on to a laptop’s lid or a small LCD monitor.

TP-Link had their 450Mbps three-stream dual-band dual-radio router with Gigabit on bot WAN and LAN Ethernet connections. As well they fielded a single-stream 150Mbps USB stick as the TL-WNT23N.

They also tried their hand with IP surveillance with the TL-SC4171G camera . This camera can do remote pan-tilt, and 10x digital zoom. It connects to the network via Ethernet or 802.11g Wi-Fi (not that much chop nowadays) and is equipped with an IR ring for night capture, as well as a microphone and speaker.

Netgear were more active with the 450Mbps three-stream routers with Gigabit LAN. Two of the models are broadband routers with Gigabit WAN, while one is an ADSL2 modem router which I think would serve the European and Australian markets more easily. The top-end model of the series has a USB file server function which works with the DLNA Home Media Network and also with Tivo “personal-TV devices”.

They also released the XAV5004 HomePlug AV switch which is the 500Mbps version of the their earlier “home-theatre” four-port HomePlug switch. Of course, they released the XAV2001 which is a compact “homeplug” adaptor which connects to the regular standards-based HomePlug AV segment.

They also have released the MBR1000 Mobile Broadband Router which works with 3G/4G wireless broadband or  Ethernet broadband. This unit is being provided “tuNrnkey” for Verizon’s new 4G LTE service.

Netgear have also fielded the VEVG3700 VDSL2/Gigabit Ethernet dual-WAN router with Gigabit Ethernet LAN, Cat-IQ DECT VoIP phone base station. This device, which is pitched at triple-play service providers also supports DLNA server functionality. As well, they also had a DECT VoIP kit available for these providers

As well, Netgear have tried their footsteps in to IP-surveillance for home and small business with a camera and an Android-driven screen for this purpose.

D-Link’s network hardware range include the three-stream 450Mbps routers with Gigabit WAN/LAN, a multifunction access point / repeater for the 802.11n network as well as a new DLNA-enabled network-attached storage range

As far as the MoCA TV-coaxial-cable network is concerned, Channel Master is the only company to release any network hardware for this “no-new-wires” network. It is in the form of a MoCA-Ethernet 4-port switch for the home theatre.

“Mi-Fi” wireless-broadband routers

Every one of the US cellular-telecommunications carriers are catching on to the 4G bandwagon not just with the smartphones and tablets but with the wireless-broadband routers.

Sprint have a unit for their WiMAX service while Verizon are fielding a Samsung LTE “Mi-Fi” as well as the aforementioned Netgear MBR1000 router.

Computer hardware and software

Monitors

Some of the companies who manufacture monitors are looking at the idea of “Internet-connected” monitors which have a basic Web browser in them so you don’t have to fire up a computer to view the Web.

CPU/GPU combo chips

These new processor chips combine a CPU which is a computer’s “brain” as well as the graphics processor which “draws” the user interface on to the screen. AMD and Intel were premiering the “Accelerated Processor Units” and the Core “Sandy Bridge” prcessors respectively at the CES this year.

Intel were trumpeting the fact that this technology could make it harder to pirate movie content but this is more about mainstream computing and small-form-factor hardware being behind this space and power saving processor hardware.

Sony had lodged a commitment to AMD to use the Zacate “Accelerated Processor Unit” in some of their VAIO laptops.

Other hardware

AMD haven’t forgotten the “performance computing” segment when it comes to processor chips and released the quad-core and 6-core “Phenom” desktop and gaming-rig CPUs.

Seagate have also made the “GoFlex” removable / dockable hard disks a standard by building alliances with third-parties to make hardware that works to this standard. Could this be another “VHS-style” alliance for dockable hard disks?

Microsoft also used this show to premiere their Touch Mouse which uses that same touch operation method as Apple’s Magic Mouse. Do I see an attempt for them to “snap at” Apple when it comes to “cool hardware” as well as software?

The Microsoft Platform

There has been some activity with the Microsoft Windows platforms now that set-top boxes and tablet computers are becoming the “order of the day”

One direction Microsoft is taking is to port the Windows Platform, which was primarily written for Intel-Architecture processors, to the Acorn ARM-architecture processors. The reason that this port is taking place is due to these energy-efficient RISC processors being commonly used in battery-driven applications like tablet computers. They are also popular with other dedicated multimedia devices like set-top boxes and TV applications.

As well, Microsoft will be working on a lightweight Windows build for TV applications like set-top boxes. This is although they have previously written Windows-CE builds for this class of device.

Microsoft also want to make a variant of the Windows Phone 7 for tablet computers and are starting work on the Windows 8 project.

Similarly, Somsung has demonstrated the second incarnation of the Microsoft Surface platform This one comes in a slimmer table-based form rather than a unit that is as thick as the 1980s-style “cocktail-table” arcade game machine.

Conclusion

The Consumer Electronics Show 2011 has certainly put the connected home on the map. This is due to affordable smartphones and tablet computers becoming more ubiquitous and Internet-provided video services becoming an increasing part of American home life.

It will be interesting to see what will happen for the other “pillar” of the consumer-electronics trade fair cycle – the Internationaler Funkaustellung; and how more prevalent the Internet TV, smartphone and tablet computer lifestyle will be in Europe and Asia.

Tune into the world with the latest T-Hub software update – Radio, Software, Global | Telstra Exchange

My comments

Previously, the Telstra T-Hub multipurpose Internet device had an Internet radio function but this was limited to receiving the Internet streams of Australian radio stations. Most of us would think that this is limiting because of radios like the ones reviewed on this site being able to pick up Internet streams from overseas radio stations or the fact that we could use vTuner or Reciva web sites to “tune in to” these streams.

There had been a lot of discussion about this on Telstra’s “Exchange” website especially as they were about to release new software for this device, especially with a desire to have this functionality on board. Now Telstra have answered these calls by integrating the fully-fledged Internet radio functionality in to the T-Hub as part of the latest (version 1.10k) firmware update.

Someone raised in response to this article an issue about whether the Internet-radio service would be counted towards one’s Internet-traffic limit and there is a fear that it may not be so for overseas stations. Another key issue that also has to be resolved would be the quality of service that one gets with Internet radio because, as from my experience, there are times where there is increased jitter and latency with Internet radio stations especially when the station’s home country or we enter peak Internet-use times.

This news is also of interest to manufacturers, distributors and users of other multipurpose Internet devices that are intended to supplant or supplement landline-telephone functionality.

How to update the T-Hub to the latest version

1. Touch the “Settings” icon on the T-Hub’s second home screen
2. Touch the “Software Updates” icon.
3. Touch “Check for New Software Updates”. This will identify if the T-Hub is on the latest firmware or whether there is an available update.
4. If an update is available, touch “Download Now” to start the update process.

Der Devolo dLan 200 AV Wireless N organisiert Ihr Heimnetzwerk – COMPUTER BILD

From the horse’s mouth

Web page for this product (Deutschesprachen, English language)

My Comments

Previously, Netgear had released an 802.11n wireless access point which can connect to an Ethernet network or a HomePlug AV powerline network. This is a product that I had commented on as being suitable for extending the coverage of an 802.11n wireless network or establishing the footprint of your home network in to an outbuilding or static caravan that you are using as part of the house.

Now, Devolo have answered Netgear’s effort by releasing a similar product in the European market which also has a 3-port Ethernet switch.  This unit, which sells in Germany for €109.90  has similar WiFi functionality to the Netgear unit, including WPA2 security with WPS push-button setup. As far as I know from the research I have done at Devolo’s Website, this unit doesn’t seem to support WPS-based quick setup for multiple-access-point wireless networks – the WPS function only works for setting up a wireless client to the access point. This function could be added to this unit through a firmware update.

The 3-port Ethernet switch would come in handy for a lounge area with an Internet-enabled TV, a Blu-Ray player and/or a games console; or an office set up in the garage or barn where there is a desktop computer and / or a network printer. It also can come in handy if you have to use this HomePlug AV access point with another HomePlug AV-Ethernet bridge to extend the coverage of your HomePlug AV powerline network to another building or caravan as I have explained here.

At least someone else has come up with another HomePlug AV wireless access point for the home network and have taken this concept further by adding a 3-port Ethernet switch rather than the typical Ethernet port found on this class of device.

LaCie Intros ‘Wireless Space’ Wi-Fi Router / Access Point / NAS Media Server All-in-one | eHomeUpgrade

Video direct link

My comments

There have been previous attempts to combine a network-attached-storage device with a broadband router but most of these have resulted in devices having the worst of two worlds unless you build a computer to work as this kind of device. Mostly you have a “storage router” which is a regular wireless “edge” router which can convert a USB-connected storage device in to a network-attached storage or a network-attached storage which can serve two networks and offer elementary routing functionality.

But LaCie have made a better attempt to bring the best of both worlds together. They have released the “Wireless Space” which is a NAS with integrated wireless-router functionality in a beautiful piano-black housing.

The network-attached storage can do what most single-disk systems can do such as offering integrated backup using operating-system-integrated backup functions that are part of Microsoft Windows or Apple MacOS X. Of course, files can be stored using the SMB or CIFS in a network-public share or a private share and the unit can provision media using UPnP AV / DLNA or Apple iTunes. One feature that I would like to know about with the UPnP AV media server is whether it can work with the full metadata for audio, image and video files or simply provide a folder view.

The unit can be set to work as a wireless “edge” router, a wireless access point or a wireless client bridge which provides for high flexibility, no matter whether you want to keep your existing broadband router going or replace it with something better. There are 3 Gigabit Ethernet ports for the LAN side of the connection and one Gigabit Ethernet port for the WAN (broadband) side of the connection, which makes this unit fit for use with “next-generation broadband” setups. The wireless network is based on 2.4GHz 802.11n technology and can use WPS quick-setup options.

When the unit works as a broadband router, it has the full expectation for a mid-range broadband router including UPnP Internet Gateway Device functionality and VPN pass-through. If it works as a switch, it can work alongside UPnP Internet Gateway Device routers to enable remote access to the network-attached storage resources.

It could have support for 4-port switch functionality when in switch mode rather than the 3-port switch + “recovery port” functionality that it has. As well, it could do well with support for WPS-assisted “extension access point” setup so it can work quickly and easily as part of an “extended service set”. Of course, I would prefer to hook this device to a wired backbone or run it as a wireless broadband “edge” router in order to avoid putting your data at risk due to the radio-interference risks associated with wireless networking and the fact that the wireless network is a shared-bandwidth network.

This may raise questions about this device being an “infill” NAS/access-point network device for a small network or being a replacement for an existing broadband router such as to “fatten the pipe” for next-generation broadband.

Mobile codes to boost Google account security | Security – CNET News

My comments

Google have worked on a way of improving security for Web-page login experiences because these login experiences are easily vulnerable to phishing attacks.

What is this technology

This method is similar to a hardware security “token” used by some big businesses for data security and increasingly by some banks to protect their customers’ Internet-banking accounts against phising attacks. This is a device that you keep with you in your wallet or on your keyring which shows a random number that you key in to a login screen alongside your user name and password and is based on “what you have” as well as “what you know”.

This time, the function of this “token” is moved to the mobile phone which nearly all of us have on ourselves. It will appear as a smartphone “app” for the Blackberry, Android or iPhone platforms that shows the random code number or will operate in the form of your phone showing an SMS with the token code or you hearing a code number from a call you answer on that phone. Of course, you will register your mobile number with Google to enable this level of security.

The direction for the technology

Google are intending to use it with their application platform which covers GMail, Adsense, Analytics, Picasa and other Google services. Initially it will be tried with selected user groups but will be available to the entire user base.

They will provide an option to avoid the need to use this “Google codes” system on the same computer for a month, which would appeal to users who work with their GMail account from their netbook or desktop PC. They will still need to have this work if they “come in” to their GMail account from another computer and it will work if someone else uses the same PC to check on their GMail.

What I am pleased about with this is that they intend to “open-source” this system so that it can be implemented in to other platforms and applications. Similarly, the “apps” can then be ported to newer smartphone platforms or “baked in” to other PDAs and similar devices. As far as the “apps” are concerned, I would like to allow one piece of code to service multiple service providers rather than loading a smartphone with multiple apps for different providers.

Making the home network secure

I would like to see this technology being tried out as a method of securing devices that use Web-based data-access or management interfaces, similar to D-Link’s use of CAPTCHA for securing their home-network routers’ management login interfaces. This is becoming more so as nearly every home uses a wireless network router as the network-Internet “edge” for their networks. Similarly, there is an increasing tendency to use a network-attached storage for pooling data to be available across the network or as backup storage and most of these units use a Web-based user interface.

Conclusion

One feature that I like about this Google project is that they have applied a security technology normally available to big business and made it available to small business and consumer users.

Panasonic Adds A Twitter App To Its Viera Cast Plasma HDTVS

My Comments

First, they did it by enabling video conferencing with Skype, now Panasonic are allowing you to Tweet a comment about that show you are watching or follow your Twitter friends on your lounge-room TV. Who knows not if but when Facebook will become the next add-on for Panasonic’s Viera-Cast TVs and Blu-Ray players. These sets will also need to work with a remote control that has a QWERTY alphanumeric keyboard so you you can get those Tweets or status updates out as that show progresses.

This happens to be highly relevant as an increasing number of television shows, mainly sports, talk shows, current-event broadcasts, reality TV and the like integrate Twitter in to their content and have set up a particular hashtag associated with that show. This typically includes the use of a “Twitter crawl” that appears at the bottom of the screen and / or the show’s compere or anchor citing selected Tweets directed at the show.

It is becoming the direction for manufacturers to extend the common social-Web and Internet-driven-communications platforms to a “10-foot” experience on the lounge-room TV or video peripheral (Blu-Ray player or “personal-TV service”) either by providing the function as an “app” that you choose from an “app-menu” or “app-store”; or as part of a firmware update that is rolled out to the device.

This may require a change in the direction on how the remote control for the TV set is designed. This may be in the form of a handset that mimics the Nokia N97 Mini smartphone where the top of the remote swings away to reveal a QWERTY keypad; a handset that looks like a BlackBerry or Nokia E-Series smartphone or simply an app for the common smartphone platforms which provides TV control as well as a link between the phone’s text-entry keyboard and the TV. It may also mean that the infra-red remote control will go the way of the ultrasonic remote control and be replaced by a Bluetooth or Wi-Fi remote control. Other solutions may also include support for standards-based Bluetooth keyboards like the Logitech diNovo Mini or Microsoft’s Media Center keyboards.

In this case, there will need to be an interest in designing more of the multimedia keyboards that appeal to being operated while you are slouching on the couch. This will mean keyboards that are backlit when they are used, small keyboards that can be worked with two thumbs; keyboards resistant to damage from crisps (US: chips) and sweet drinks that are often consumed in front of the telly and elegant-design keyboards.

Now it will certainly mean that the TV isn’t just for watching your favourite shows any more. It will also be about integrating the social Web with the experience.

Seagate introduces GoFlex Home for household network storage | The Toybox – ZDNet

From the horse’s mouth

Seagate –

Product Page

Press Release

My comments

Seagate had previously released a docking hard-disk system under the FreeAgent name, with a USB dock, media-player dock and the DockStar which is a network-attached storage which works with the FreeAgent docking hard disks.

This unit was based around the PogoPlug technology which has an Ethernet-ended network-attached-storage circuit in the same space as a “wall-wart” AC adaptor. It was able to support these functions:

• “cloud-based” file sync
• file backup either with supplied software or operating-system-native software in the form of Apple Time Machine or CIFS
• a DLNA-compliant media server or
• Remote file access from the Internet

Now, Seagate have established a new “FreeAgent” docking hard-disk form factor in the form of the GoFlex, which has some different attributes to the previous standard. Why has this action been taken?

One issue that may be of concern is the desire for Seagate to move from one platform to another but keep a few products going to support those who have the established platform.

Whatever, I would consider this NAS design as being suitable for use with a small network or as a secondary unit for a larger network. One application that I would think of for these units would be as a DLNA media server for a small-business network that has a dedicated server computer running something like Windows Server or a Linux business server build for company data. This unit would, as outlined in “DLNA and UPnP AV in the business”, hold media like pictures or videos to show using DLNA-capable TVs and electronic picture frames as part of the business’s visual merchandising strategy without putting business-critical data at risk.

NETGEAR Adds Gigabit PoE Smart Switch – SmallNetBuilder

From the horse’s mouth

NETGEAR GS110TP Gigabit PoE switch product page

NETGEAR GS-110TP Gigabit PoE 8 Port Smart Switch

My comments

The concept of VLANs and quality-of-service functionality is now become increasingly relevant to the home and small-business network now that the “single-pipe triple-play” and “next-generation” broadband Internet services are either here in your market or are coming around the corner to your market.

What are VLANs

The VLAN is a separate logical network path within a physical network medium, such as multiple SSIDs from one Wi-Fi access point serving different networks or a HomePlug setup with multiple Network Passwords for different networks. Most business-grade Ethernet switches offer this functionality in order to have particular Ethernet sockets associated with particular logical networks. It is used in many network applications such as interlinking a business with multiple premises through one multi-tenant building or providing Internet-only “guest access” service to business networks.

Now the VLAN is becoming common in small networks as part of either providing “guest access” or “hotspot service” to the Internet without encroaching on the security of the resident network; or providing dedicated “fast-lanes” for quality of service when it comes to A/V streaming or VoIP service.

NETGEAR’s role in this equation

Now NETGEAR have provided the GS110TP Gigabit Power-Over-Ethernet Smart Switch which is an 8-port switch which offers this functionality and Power-Over-Ethernet to all the ports for US$260. This is similar to how this company offered 5-port and 8-port 10/100Mbps Cat5 Ethernet hubs and switches at prices affordable for most people when the idea of home networking and broadband Internet came on the horizon in the early 2000s. Then a few years later, they offered 8-port 10/100Mbps switches with that had 802.3af standards-based Power-Over-Ethernet supply functionality on four of the ports, again at a price that most users can afford.

It may be easy to think of this unit being a candidate “central” switch when you wire your premises for Ethernet and want to make it future-proof for these new requirements. There have been some concessions to allow it to work properly with “triple-play” by the use of a default VLAN matrix with one VLAN for regular traffic, one for VoIP and one for video traffic. There is some “automatic-transmission” logic that shifts data to the different VLANs based on whether the data was primarily multicast in the case of video or one of a few VoIP protocols in the case of VoIP.

The main problem with this is that this switch wouldn’t work in a “plug-and-play” manner with “edge” devices that use certain VLAN setups or QoS methods to assure video and VoIP quality-of-service. For example, most of the “n-boxes” (Livebox, Neufbox, Freebox, Bbox, etc) used by French “triple-play” service providers as network-Internet edges have one Ethernet port for video traffic and three Ethernet ports for regular traffic. These units would expect you to connect the IPTV box to the “video” Ethernet port and you may end up with QoS or installation difficulties if you used this switch with them.

Limitations with this class of switch

For these switches to become easier to implement in a home or small-business network, there would have to be standards that allow an “edge” device to communicate its QoS and VLAN needs to these switches. This may be important if the “edge” device is managed by the service provider or is part of the provisioning chain that a service provider uses.

This may also include the flexible installation and “at-will” relocation of devices like VoIP handsets or IPTV devices as well as the support for multiple devices of this type across an Ethernet backbone. It also includes the support of multiple cascaded switches such as “regional” switches in other parts of the building or other buildings.

Other benefits to take note of

One bonus that I like about this switch is that it has offered 802.3af-compliant Power-Over-Ethernet across all Ethernet ports which allows the Ethernet cable to be a power cable as well as a data cable.This technology, which I will cover in a separate article on this site, has been pitched at business networks as being suitable for powering Wi-Fi access points, VoIP telephone handsets and IP-based surveillance cameras with one cable and from one point. Infact, NETGEAR have released an 8-port “regional” smart switch that has similar QoS and VLAN functionality but can be powered from this switch or other standards-based Power-Over-Ethernet networks.

Another feature that also appealed to me about this switch is that a unit of this price was equipped with optical-fibre LAN connectivity which can reduce the cost of using optical-fibre as a high-reliability long-distance link between buildings, especially on large properties. 

Conclusion

This is another example of NETGEAR offering technology that is deemed “large business” at prices that home users and small business can afford.

My comments

I was not surprised with the Google Android software  being implemented as an embedded-applications platform beyond the smartphone and Internet tablet. Here, “People Of Lava” have introduced a range of Internet-connected main-lounge-area television sets that use Android as their operating firmware. In fact, what’s more is that these sets are open to the Google Android Marketplace so that users can add extra functionality to them by drawing-down the appropriate apps.

What I also liked about this design was that a lot of the design costs were cut out for the manufacturer because they didn’t need to design an operating environment from the ground up when they wanted to design the equipment. It has also provided an easier path for user customisation, which may be of benefit with Internet-based TV services like IPTV and catch-up TV; and sets deployed in hotels and similar businesses.

This has then proven that the Google Android platform can become a serious contender for the embedded and dedicated-purpose operating system marketplace.

My Comments

Most of us who run a network-attached storage device will realise that these devices will need to have constant power supply in order to keep the data safe. The common solution that we would take would be to connect the NAS’s AC power supply through an uninterruptible power supply. These devices have a built-in battery to provide enough power to allow for an orderly shutdown of the device or allow the device to run longer through a short outage.

Now Thecus have taken a cue from a common security-system design practice. This is where an alarm system has an integrated battery that is maintained by the system’s power supply. It is so that the alarm system can continue to protect the premises if there is a power outage.

They have extended this concept by providing an optional battery-backup module for the N4200 “muscle-NAS” unit as an alternative to a UPS setup, with the battery allowing enough power for an orderly shutdown or completion of firmware installation. This can also cater for power outages including situations where the device may be accidentally unplugged and may be enough for most home and small-business environments.  If the NAS is used with an UPS, it could allow a larger safety margin for the data through the provision of “dual-layered” battery backup arrangement.

The concept may be worth it for equipment that is used in the home or by small businesses and would be a must for places where the power supply is likely to be unreliable. It also is another example where the manufacturers are racing to build the best example of a top-end network-attached storage device for the home or small business in a similar way to what Ford, GM and Chrysler were doing in the late 60s and early 70s with the “muscle cars”.

Samsung’s explanatory video clip

My comments on this technology

Same desirable attributes as the OLED displays, but improved in significant ways. Ability for the display to have integrated touch-sensitivity, This leads to slimmer touchscreen handsets which is an increasingly-important application in the now-competitive smartphone market, as well as similar applications like remote-control handsets and personal media players.

They have improved the outdoor viewing ability and display responsiveness for this display, which would be of benefit to mobile phones as well as digital-imaging and handheld-games-console applications. But do I see this technology going further? Another application that I could see the Super AMOLED work well with is a watch which works as an auxiliary display and control unit for mobile phones, like some of the Sony Bluetooth watches that have been surfacing lately. Such watches could then permit a colour display on the wrist with various interesting applications.

An area where this Super AMOLED technology could excel would be automotive and marine applications, especially if the cost of larger-area displays comes to a par with the common LCD displays. For example, the new multi-function displays that are becoming the control point for HVAC, infotainment, navigation, and similar applications in newer cars could move towards this display technology. Similarly, this technology could appeal to personal navigation devices a.k.a. “sat-navs” or GPS units, marine GPS / fish-finder units as well as aftermarket car-audio equipment.

What I see is that the Super AMOLED could be one of the next key display technologies as was the LCD or the LED displays.

My comments on this idea

The common situation with most TV households is that if they sign up to a pay-TV service like Foxtel (Australia), a local cable-TV franchise in the USA, DirecTV (USA) or Sky TV (UK), they can only watch TV through the set-top box provided by the service provider. The TV remote control ends up becoming redundant as they have to use the set-top box’s remote control for their TV viewing.

If they want to use a DVR i.e.. a “personal TV service”, they have to use the DVR option provided by the pay-TV provider rather than get a retail DVR solution like TiVo, a home-theatre PC such as Windows Media Center or one offered by a major consumer-electronics brand. In some situations like some cable-TV implementations in the US, you may be able to use a retail DVR solution along with a special “CableCARD” and, perhaps, a “tuning adaptor”. But this doesn’t provide the full service that the customer has put money up for, such as interactive TV or access to “pay-per-view” or “on-demand” content.

As well, a lot of these providers often charge an extra fee if the user wants to deploy a set-top box in other rooms. This typically means that one TV set, usually the one installed in the main lounge room or family room, is subscribed to the pay-TV service. At best, most users may deploy the second set-top box in a secondary lounge area like the rumpus / games room.

What is the layout preferred by TiVo, Sony and others?

The layout would consist of the following:

• A “gateway device” or broadcast-network tuner connected to the cable service or satellite dish which “tunes” the pay-TV services and manages access to these services. It then makes them available over the home network using IP-based standards and technologies.  This device can also pass back information relating to “pay-per-view” content orders or interactive television from the endpoint devices. It can also handle on-demand content offered by pay-TV providers in the convention context and fulfil the content to the desired end-devices.
• Standards-compliant endpoint devices (TV sets, DVRs, etc) that are connected to the home network and discover the services and content using technologies like DLNA. These devices can work with interactive services provided by the TV service provider and provide the viewer’s responses to the gateway device via the home network.

This is similar to the “broadcast-network tuner” setups like Devolo’s dLAN Sat, the Tivit ATSC mobile DTV WiFi tuner and the HD HomeRun tuner, where there is a digital-broadcast tuner that passes the signal via an IP-based home network to a hardware set-top box or software player program in a general-purpose computer so people can view the TV programme. These solutions typically used a non-standard control method and, in most cases, a single RF front-end so that only one TV set could operate at a time and they couldn’t work with a DVR or similar device.

Why develop this layout?

There is a desire for true competition in the multichannel pay-TV industry concerning end-user devices that is similar to what has occurred with telephone hardware since the Carterfone Decision in the USA and the Davidson Inquiry in Australia. One of the goals is to provide a TV navigation interface that encompasses off-air, pay-TV and IP-delivered content in the one electronic programme guide. This guide’s interface would be “skinned” to match the host device’s branding or any user customisations that are available to the device’s user. It also means that the user only needs to deal with one remote control to find whatever they want to watch.

This kind of layout could allow each TV set and each computer in the house to have access to all of the pay-TV services, rather than the common situation of having to deploy pay-TV set-top boxes to each place where there is a TV set.

There is the ability to upgrade the gateway to suit changing technological needs such as change of infrastructure or improvement in transmission or security protocols. That same ability also exists if the user wants to change providers or sign up to a supplementary-content service. Here, in all the situations above, there is no need to replace the end-user’s devices like DVRs or Internet-enabled TV sets, nor is there a need to replace software on any of the computers in the house to accommodate these changes.. In these cases, the software or firmware can discover the new services that are provided through the new hardware.

What needs to happen

One thing that needs to happen is high-profile implementation of common standard technologies like UPnP AV in the broadcast-reception sphere. This includes having endpoint and recording devices work to these standards when discovering and receiving broadcast signals via an IP network. It also includes the recognition of electronic-programme-guide data provided by these gateway devices, especially if the device that benefits from the data is a recording device like a “personal TV service”. It doesn’t matter whether the client device has the programme-guide data or the broadcast-network tuner has that data. This also includes handling situations where the same broadcast service can be received through different paths such as one or more over-the-air channels and / or a cable or satellite service.

In a similar light, broadband routers that work as the network-Internet “edge” could work as a “gateway” for IPTV services by storing channel lineups and service-authority information for these services.  This device may also have to support handling of interactive-TV sessions in situations where the endpoint device cannot handle the sessions itself.

As well, interactive-TV setups would need to work with an IP backhaul irrespective of whether the TV signal is delivered via RF (cable, classic-TV-aerial or satellite) means or via an IP feed. This also includes allowing access to downloaded assets associated with interactive content.

Conclusion

As mentioned before, what needs to happen is the use of common standards and device classes to support broadcast-network tuners; standard viewing and recording devices; and the home network in order to democratise the provision of pay-TV services.

Dual-touchpad laptop from Asus and Bang & Olufsen – CNET Crave

My comments

There are those of you who may own or have used Bang & Olufsen hi-fi systems or TVs and have become amazed at the beauty of these Danish design masterpieces. Then when you switch on any of these masterpieces, your experience with them is so special, with such benefits as high-quality sound and pictures and a distinct “feel” and user experience.

You may be wondering when this kind of experience will appear on your computer and may have thought of using the Apple Macintosh as a way of coming closer to this experience.

Now Asus have brought this experience closer to the Windows PC user through the release of a laptop computer that has been designed in conjunction with this company. David Lewis, who is a freelance industrial designer who has designed most of the classic B&O masterpieces such as the Beosound 9000 music system and the Beovision LX and MX series of television sets, has been responsible for the key aspects of this design. Similarly, the pictures of this computer when it was open reminded me of the Master Control Panel that was part of the Beosystem 6500 music system, especially with the black keyboard area and the polished-aluminium palm rest. The screen bezel had the speakers integrated in it and was wider than the keyboard area. This made it have the look of one of B&O’s newer flatscreen TVs.

None of this design is complete without there being improvements in the sound-reproduction department. Here, they also used the B&O’s ICEPower Class-D switch-mode power amplification technology, which is known to be one of the few amplifier designs of this type that yield high-quality sound.  The main reason that the speakers are in the screen bezel, rather than facing upwards from the keyboard area, are to focus the sound at the user. This is the common setup practice for sound playing to the audience and is used for hi-fi, TV sound, desktop PCs and other common speaker-based sound reproduction tasks.

With Asus becoming involved with one of the few “audio companies of respect” to design a high-end laptop computer, this certainly shows that there is effort being taken in improving the sound quality of these computers. If this happens further, the quality of the sound that emanates from this class of computer could be improved rather than us having to stick with the usual weak tinny sound or connect these computers to external speakers for better sound reproduction.

These computers also used a “dual-touchpad” design which is often described as being similar to how a master DJ cues up records on his two turntables. This then allows for increased control of the computer, especially when scrolling through material.

Of course, the specifications and software provision are not dissimilar to a high-end multimedia laptop running Windows 7.

This also means that people who work with the Windows operating system can still benefit from classy and elegant computer designs. Once we see computers like this appearing on the market, there will be the desire to offer something that bit extra when it comes to the business-personal laptop computer.
