Introduction

Previously, I reviewed the 2008 version of the Western Digital WDTV Live network media player and found that there are some areas where it could be improved on. Now I have been offered the latest iteration of this network media player for review and this review will be an interesting exercise to compare it to the previous model.

Price

Recommended Retail Price: AUD$149

Functions

Online functions will change as the device’s platform evolves and will vary by country.

Connections

The media player itself

WDTV Live network media players - earlier version below 2011 version

The current edition of the Western Digital WDTV network media player is the similar size to the previous-generations of this network media device but is finished in a newer style with an obvious infrared-remote receiver and an upfront USB socket for memory keys and hard disks. It doesn’t have the “book-style” shape as the previous model and is pitched as a unit to go with a cluster of consumer-electronics equipment.

Connectivity

The WDTV Live’s audio-video connections are similar to the previous model except that there isn’t the component video output jack. This is meant to assume that this device will work with the flat-screen TVs that have the HDMI connection or the legacy CRT TVs and video projectors that use the composite video connection for their external video devices. You still get a breakout cable with 3 RCA plugs on the end so you can connect this device to most of these TVs, in a similar way as you would with most smartphones and some digital cameras.The previous version of this device was a “Wi-Fi ready” device in that it required the user to purchase an additional USB Wi-Fi network adaptor dongle and plug it in to the unit. This time, the WDTV Live comes with the Wi-Fi network adaptor integrated in to the unit and is how I tested the unit.Front view of current model and earlier model

The Wi-Fi connectivity is set up for 802.11g/n wireless networks and supports wireless routers that implement consumer and small-business security methods i.e. WEP and WPA(2)-PSK, including WPS quick-setup routines. The latter can be started from the TV screen through the WDTV Live’s setup menu.It is still sensitive enough for most interactive-TV applications and standard-definition viewing but I would recommend using the Ethernet connection with a HomePlug AV adaptor (if necessary) for better and more reliable throughput.

User Interface

Remote control

The menu structure and user interface was more like an XBox 360 with recent firmware than the previous model’s interface which reminded me of the XrossBar interface used in Sony’s connected consumer electronics. Here, this interface was able to still work well even with legacy CRT TVs because of having the selected option in the centre and brought up.

It also used the “coloured function buttons” on the remote control which is the trend for consumer video equipment. Here this was used for applying filters or changing list orders for content and other lists. This is compared to the user using a D-pad to do all the control on this device which was the case with the previous model.

Applications

I have tried some of the services that come with the system and have noticed that YouTube comes with two user interfaces. One feature that I liked with this YouTube application was that it was able to cater for multiple users. This meant that it held the Google usernames of previous users in memory so different users can log in to their personal user profile and is a step in the right direction.

As far as the Facebook app is concerned, it is totally broken in that it can’t show the photos that are part of the social-media service. You don’t even see the profile pictures for your Facebook Friends, which makes for a disappointing experience with this device. You could see the text on the various Walls or Feeds that you subscribe to and post text-based comments but that’s all.

Most other photo and video applications work as required and the streamed videos and audio content come through smoothly. This is even though I was using it on an older “classic” TV set.

UPnP AV / DLNA

The UPnP AV / DLNA experience that the WDTV Live provides  is still the same as the previous models in that when it comes to photo and video content, it’s slow to load off the network. You can still “pull” content down from your MediaServer device like your NAS using the remote control and the on-screen user interface but the WDTV Live doesn’t work well when pictures or video content is “pushed” to it under the control of a control point.

This could be improved with read-ahead caching and proper handling of queue lists which would be important for this class of device. Once this is ironed out, it could make the WDTV Live media player become a cost-effective tool for network-based content playback including digital signage for the small business.

Limitations and Points of improvement

One main limitation with the WDTV Live family is that it doesn’t support any of the catch-up TV / video-on-demand services that are currently available for the Australian and New Zealand markets like ABC’s iView or the Plus7 service. I have seen other devices including Sony’s BDP-S380 offer this kind of functionality which would bring these services to how they should be enjoyed – relaxing on the couch and watching on the big screen TV.

But personally I would like to see the device’s software and hardware re-engineered for better network and Internet performance. This was also confirmed to me by a close friend who bought the same device and found it didn’t perform as well as it should.

As well, Western Digital could make the next or subsequent generation of this device part of a DLNA-driven multi-room PVR setup for broadcast TV. Here, they could use a box with a hard disk for recording TV shows from a cluster of ATSC / DVB-T front-end tuners using an electronic programme guide. As well, this box is managed by any device compliant with UPnP AV version 4 such as next-generation WDTV Live boxes, allowing for scheduling of TV programmes and bookmarking (shift between viewing locations) amongst other functions.

Conclusion

At the moment, I wouldn’t really recommend the WDTV Live in its present incarnation and would like to see the arrival of cost-effective video-based network media players that have access to the full plethora of network media services and work responsively and properly for the DLNA Home Media Network whether under “pushed” or “pulled” conditions.

Audio and VIdeo

Smart TV

There is still intense interest in the smart-TV platforms where your TV is effectively a computer connected to the Internet. This is more so with the idea of integrating multiple viewing screens ie the large TV screen, one or more computer screens, and the screens on tablets and smartphones.

Sony have been dabbling with the Google TV platform, mainly in the form of network video peripherals rather than a TV, which I will mention below. Of course, they are still maintaining their Bravia platform. They were also to promote this concept in a Las Vegas wedding at the Bellagio Wedding Chapel between “Bravia” (Sony’s Internet TV platform) and “Sony Entertainment Network” (Sony’s online content entity).

As far as the interactive-TV lineup goes, Sony have focused this function across their HX and EX “lounge-room” models with the HX series being ready for Skype once the user purchases an optional camera.

Samsung have devoted most of their press event to the TV being the “smart hub” of the connected home. This is with the use of a connected TV chassis that has a dual-core CPU, as well as building up the “Smart TV” platform around an app store and a video-content-distribution platform. They even are using an Android app as the TV’s remote rather than supplying the remote with the TV set. They even ran a competition for the development of a multi-screen app which makes best use of the TV screen alongside a smartphone or tablet screen.

As well, Samsung put forward an “open-frame” design for TV sets with a user-upgradable computer processor. This is in a similar way to how the desktop computer has been designed and is underscoring the fact that these smart TVs are really large-screen computers in their own right and are expected to last for in the order of ten or more years.

Even Lenovo had come to the fore with a 55” LCD set that is driven by the Android “Ice Cream Sandwich” operating system. This would link to their own app store and cloud services and have the usual “smart-TV” features like Wi-Fi connectivity and ability to use an SD card as storage.

Similarly, a “fork” of the Ubuntu Linux distribution, which was targeted at the Internet-enabled TV set, had been launched at this show.

Ultra-high-definition TV

Another main trend surfacing this year at the Consumer Electronics Show is ultra-high-definition TV, also known as UDTV or 4DTV. This is where images have a resolution of 3840×2160 pixels and is pitched at the very large screens of 103” and bigger.

LG is intending to demonstrate an 84” prototype set which works at this resolution while Sony even had the idea of having some of their Blu-Ray players upscale the 1080p video to the higher resolution offered by this newer technology.

3D TV

The main trends affecting this technology are glasses-free 3D screens where you don’t need to wear glasses to watch the 3D effect; use of cheaper cinema-style passive 3D glasses which don’t need to link to the set or require batteries; as well as standards-based active glasses systems.

Toshiba is launching a glasses-free QFHD 3D TV 

OLED as a TV display technology

LG and Samsung have made efforts to bring the OLED display technology to the living-room TV size. Here, they have proven it by demonstrating 55” TV sets that use this technology rather than the LCD or plasma technologies for their screens.

There were rumours that Sony was to dump OLED technology for TV displays but they wanted to refine it to a cost-effective point for professional and consumer users. They have also shown a “Crystal LED” screen prototype which works in a similar vein to LED screens used in public places but implemented on 55” displays.

Other TV news

Some classic names of respect are using this fair to strengthen themselves in the American market. Westinghouse have launched a 3D TV but none of their sets came with Internet-enabled TV functionality. This was to keep their sets at an affordable price point.

RCA had rebuilt their name on a large run of TVs for the North American market as well as fielding a 55” Internet-enabled TV for the Latin-American market. They were using this show to launch some Android-powered mobile TV sets for the up-and-coming “Dyle” mobile / handheld terrestrial TV platform in North America.

Speaking of Dyle, Belkin and MCV were launching an array of equipment and accessories so that people can benefit from this mobile TV platform.

Home-theatre and Hi-Fi

Samsung had used this show to launch two soundbars with iPod / Galaxy S / Allshare (DLNA) integration with one being based on hybrid valve / digital amplification technology. They also ran with two Blu-Ray-based home-theatre-in-box setups with “Disc-Digital” which is Samsung’s implementation of the UltraViolet “digital video locker” service as well as the 7.1 channel unit being based on the above-mentioned valve-digital hybrid amplification technology. The other 5.1 channel version implements a wireless link for the back speakers and both systems use Wi-Fi to link to the home network.

Samsung even launched a home-theatre soundbar which can become two speakers and could link to sources via HDMI ARC (audio return path from HDMI 1.4-compliant TVs) or Bluetooth A2DP. RCA also launched a similar soundbar that connected to the home network and worked as a network media player for Netflix and similar services.

They are also implementing the “DIsc-Digital” UltraViolet implementation across the Blu-Ray player lineup at this year’s CES. One of the players is a similar size to a Discman and accepts discs through a slot while another of the players is a slimline form factor with HDMI inputs for TVs that don’t have enough HDMI sockets.

Sony have shown two Google-TV-based network video peripherals, the NSZ-GS7 which is a network media adaptor and the NSZ-GP9 which is a Blu-Ray player. As well, they have released two DLNA-capable Blu-Ray home theatre systems with full access to the Bravia Internet TV platform as well as a home-theatre receiver. Sony also released a few “HomeShare” DLNA speakers that connect to the Wi-Fi home network and have audio content pushed to them.

Panasonic have run with a large lineup of Blu-Ray players and Blu-Ray home-theatre systems. All of these connect to the home network and support DLNA functionality but the 3D-capable models and the home-theatre systems provide full access to Panasonic’s Viera Connect smart-TV platform including Skype and the Social Web for your existing TV.

These latest releases by Sony and Panasonic mean that you can use the cheaper and older TVs and have full access to the Internet-provisioned “smart TV” content and applications out there. In the case of the Panasonic 3D Blu-Ray players and home-theatres, add the Skype camera and you have just enabled a Skype-based video-conference setup,

Pioneer also used this show to launch the N-30 and N-50 audio-focused network media adaptors which work with DLNA 1.5 and Airplay network-media setups and the vTuner Internet-radio directory. They can handle 24-bit 192-kHz WAV or FLAC high-grade audio files and are Wi-Fi / Bluetooth ready with optional modules. The N-50 can also work as a high-grade digital-analogue converter for a CD player or MiniDisc deck.

Cameras

Samsung, Sony and Toshiba had launched cameras that were capable of uploading images to cloud-based photo-sharing services without the need for a computer. In the case of Sony, their Bloggie Live and Bloggie Sports cameras were being pitched as an alternative to the smartphone’s camera for Internet work.

Toshiba also exhibited a 3D camcorder with a built-in glasses-free 3D LCD screen so you can preview your 3D images properly. As well, Polaroid demonstrated a smartphone-style digital camera with a “proper” optical zoom lens – something that could be considered a bridge between a smartphone or digital camera.

Personal Lifestyle

Appliances

This show still hasn’t become a North-American showground for domestic appliances in a similar vein to the Internationaler Funkaustellung in Berlin. But LG was using this show to promote their “SmarThing” range of network-connected “white goods” which could be monitored from a computer.

Of course, Samsung also demonstrated a washing machine and clothes dryer that used a colour LCD touchscreen but was able to be controlled via an app on a smartphone. This means that you could track your washing from your phone’s screen.

Home Automation and Security

There has been some activity on this front mainly in the form of network-hardware vendors offering IP-enabled surveillance cameras, with TRENDNet offering a lineup of 12 units with varying features.

Other than that, the “Next Learning Thermostat” which learns your heating / cooling settings through the day was premiered at this show. Belkin also premiered the WeeMo home-automation system which is effectively an appliance-control module that responds to your smartphone.

Personal Health Care

There has been some more effort in developing online personal-health-care equipment which interacts with your smartphone or home network.

Withings, previously known for their Wi-Fi-connected bathroom scales, have released a baby scales which also links with the same network enablement and online health-monitoring setup as these bathroom scales. Similarly iHealth have released a wireless body-fat scales along with a wireless blood-pressure monitor and a “Smart GlucoMeter” glucose sensor for your iOS device. As well, FitBits released the Aria Wi-Fi Scale which is bathroom scales that link to your home network and measure weight, body-mass index and body-fat percentage.

IP Telephony

There has been some activity concerning voice and video Internet-based telephony. This is primarily with Skype being part of most of the “big-name” smart TVs and able to be added on to existing TVs through the use of this year’s Panasonic 3D Blu-Ray players and home-theatre systems. But Samsung also launched a Skype HD videophone unit for TVs and Biscotti launched a similar device for their own service.

RCA had demonstrated their voice-based IP telephony systems for business use while Ooma launched a cordless VoIP phone which has a colour LCD screen and can sync to Facebook for “picture caller-ID” images. $10 a month with the Ooma service provides for conferencing, second-line service and advanced call forwarding.

Tomorrow, in the last of the series, I will be talking about the network technologies that are to link these devices to the home network and the Internet.

Introduction

Western Digital WDTV Live network media adaptor

There was a trickle of component network media adaptors which provide media playback from the Internet or home network to an existing audio-video system but this trickle has now become a flood over the past few years with equipment being offered at varying functionality and cost points.

For video content, most of these devices including some of the current-model Blu-Ray players may offer “over-the-top” TV services to existing TV equipment and this may avoid the need to buy a “smart TV” for this kind of content. This would appeal to those of us who would rather spend money on equipping our home theatres with a video projector or top-notch high-performing LCD TV rather than buying a “smart TV” to keep up with the Joneses. Similarly, these devices can expose a secondary TV like the one located in the secondary lounge area or master bedroom to the plethora of online content.

Similarly, you may want to invest in an audio-based network media player so you can enjoy Internet radio or music held on the network-attached storage through the hi-fi system. This is becoming more so as high-grade audio files of classic and contemporary albums are being made available for sale and file-based audio content has now achieved hi-fi credentials.

What are these devices

A component network media adaptor like the Western Digital WDTV Live is designed to connect to existing audio and video equipment and show network-derived content on such equipment. Of course, they will work as a gateway to some Internet-hosted media services like IPTV / video-on-demand or Internet-radio services; and a few may work as a terminal for popular interactive Internet services like the Social Web.

If the manufacturer keeps investing in the device’s platform, there may be the ability for newer content services to be added to an existing device. This typically is being achieved through a continual firmware update or an app store that works in a similar vein to a mobile platform’s app store.

Sony BDP-S380 Network-enabled Blu-Ray player

Some of these adaptor devices also have functionality for access to legacy media like a radio or TV broadcast tuner and/or an optical disk player. An example of this is the Sony BDP-S380 Blu-Ray player which I had reviewed. But these devices also have a USB port, iPod dock and / or memory card slot so that content held on any of these locations can be played through the device. Similarly, the Microsoft XBox 360 and the Sony PS3 games consoles are able to serve as component network media adaptors as well as satisfying marathon TV games sessions.

A selection of these devices have an integrated hard disk and are able to work also as a media server. Some of them may allow you to add the media files by “ripping” from supported optical discs or recording broadcast material from an integrated tuner as well as accepting the content from the network or USB memory keys in a similar vein to the typical network-attached storage device.

Two main classes

NAD c446 Network Media Tuner

There are two main classes of these component devices and the class they fall in to is based on the content they are designed to reproduce.

Video-optimised

A video-optimised network media adaptor is designed primarily to reproduce video or still-image content on an attached TV or projector.

Key identifiers for this class of device include the presence of video connectors for a display device. These are typically HDMI, component or composite sockets alongside the audio sockets.

Another identifier is that there is a very small display on the unit itself which only shows content running time, or no display at all. The user is expected to operate the device using the remote control and looking at the attached video display device for visual feedback. This is common with very-low-end DVD players that don’t have a track/time display and I once saw one of these players in operation at a party and the hosts had the TV on so they know which tracks to play on a CD.

Of course, if they have a legacy media source, it will typically be something like a DVD/ Blu-Ray player or a digital-TV tuner. The online services available to this device would typically be the IPTV / video-on-demand / advanced-TV services and it may also work as a terminal for video-conferencing (with an add-on camera), interactive TV or the Social Web.

Audio-optimised

Linn Majik DS network preamplifier

An audio-optimised network media device is designed primarily to reproduce audio content, especially music.

These devices have no video connections at all or they may use any such connections for a secondary purpose. It is augmented by the device having a display and controls on its front panel for selecting and playing content or a remote control with an LCD or OLED screen as its primary control surface. This means that the device won’t be dependent on the use of an external video display for its operation.

If the device supports legacy content, the will use either a radio broadcast tuner and / or a CD / SACD player. They will also have access to audio-based Internet content sources like one of the Internet-radio directories like vTuner, Pandora or Last.FM.

What to look for

Ethernet connectivity

A component network media adaptor should have an Ethernet connection in order to provide for reliable playback of high-quality network and online content via Ethernet or HomePlug AV. You may get away with Wi-Fi wireless for Internet radio, CD-quality audio content, still images or standard-definition video content.

UPnP AV / DLNA

As well, the device should support UPnP AV / DLNA functionality. The basic level of support for this functionality is to find and play media held on DLNA media servers using the device’s control surface. On the other hand, a better-equipped device is able to play content that you push to it from another UPnP AV / DLNA control point like a lot of smartphone media-control software such as TwonkyMobile.

It also allows your device to be future-proof and is of importance whenever you look towards running specialist media-server equipment such as network PVRs on your home network.

Internet-media services

Most low-end video-optimised equipment will support fewer Internet-video services but the mainstream-priced equipment from the big brands will offer access to the popular TV services in your territory like the catch-up-TV services and the big-time video-on-demand services like Netflix.

If a device has access to online interactive services like Facebook or Picasa, only one person will be able to operate their online service on the device at a time. This functionality may just be useful for showing pictures held on the user’s online-service account but activities like updating the status comment on the service or simply logging in may be very difficult. This is due to the limited user interface that these devices offer as I have previously talked about.

Devices complementing each other

Some of these network-media adaptor devices can complement each other. For example, you may use a newer adaptor that provides access to newer content services while you have an older adaptor that the manufacturers have given up on still able to provide some of the online and network-sourced media that you are after.

Similarly, you could use an audio-optimised network media adaptor for playing radio and music sources while you have an Internet-enabled TV or video-optimised network media player coming in handy for image and video content.

Conclusion

The component network-media adaptor, whether in the form of a Blu-Ray player, set-top box or network-enabled tuner, can expose existing audio-video equipment to the world of online or network-hosted entertainment content.

WiFi Direct and DLNA get friendly, make streaming media a little bit easier — Engadget

My Comments

Just lately, the media-streaming use case has been brought to the WiFi Direct personal-area network as a competitor to the Bluetooth A2DP / AVRCP media-streaming applications.

There is an important fact that any WiFi-capable DLNA device could be a client device in this network setup as long as the host computer or smartphone is WiFi-Direct capable and running DLNA-compliant media management software. This could mean that your Intel WiDi laptop could be set to play video on that Samsung Smart TV or music on the Sony CMT-MX750Ni without needing to use an established WiFi router or access point.

What I see about WiFi Direct is that it is effectively being run as an alternative to Bluetooth for the personal-area network or standards-based peripheral link. But I am not sure whether it will succeed due to heavy emphasis by industry on the use of Bluetooth for this application and little consumer promotion of WiFi Direct capabilities.

Ericsson’s proof-of-concept solution for DLNA in the hotel room (PDF)

An example of a hotel or serviced apartment block which would be relevant to DLNA

My comments

Why DLNA in the hotel room?

Increased availability of affordable DLNA-compliant entertainment equipment

Most manufacturers who sell consumer electronics are offering electronic entertainment devices that can be connected to a home network and can pull down content from that network or the Internet. When it comes to obtaining media from the home network, these manufacturers will use the established UPnP AV / DLNA technology rather than reinvent the wheel. This feature is being promoted as a distinct product differentiator and will soon end up being offered across all of a manufacturer’s lineup except, perhaps, the very-low-end models.

Some of this equipment is available in form factors that would suit the typical hotel room, suite or serviced apartment. Examples of this include the Sony CMT-MX750Ni / CMT-MX700Ni and the Rotel RCX-1500 music systems that I have reviewed on this site as well as the increasing number of “smart TVs” offered by LG, Samsung, Panasonic and Sony. In the same context, a DLNA-compliant network media adaptor could displace a solution-specific option as the gateway to premium content in the hotel as has been investigated for residential cable TV.

Sony CMT-MX750Ni - an example of a DLNA-compliant music system for a hotel room or serviced apartment

In the case of some of the network media adaptors and “smart TVs”, it could be feasible to integrate site-specific apps or Web links to facilitate interactive services like room-service ordering or in-room checkout that have been part of hotel-based video systems.

Access to online content through mobile computing devices

Most people are making use of online content services like Internet radio, Last.fm, YouTube and Netflix on the mobile computing devices that they take with them all around the world. This also includes use of the Social Web where Facebook and Twitter profiles and pages are replete with photo and video content hosted or referred to by the profile’s / page’s owners.

Multimedia content held on users’ mobile computing devices

Another fact is that guests want to be able to bring their own content. Examples of this include music that is held on a smartphone or reviewing just-taken digital images or footage held on a digital camera or laptop on the large-screen TV.

Acer Iconia Tab A500 - an Android example of a platform tablet computer

This is being taken further by the fact that platform smartphones and tablets have DLNA controller abilities either with them or as a low-cost or free app; and that mid-range and premium cameras will be equipped with Wi-Fi and “show-on-DLNA” functionality as a product differentiator.

This concept can allow better use of site-specific media like the pay-per-view movies. For example, a movie that is started on the lounge TV in a suite or apartment could be completed on the bedroom TV or a guest could view one of those pay-per-view movies on their iPad or similar tablet.

Personally I also see this concept as part of the desire by the hospitality sector that your hotel room or apartment is your home away from home.

Requirements Of This Setup

Different Media Pools

There are three different media pools that one has to consider when implementing DLNA technology in the hotel environment.

“Own media pool”

This represents the media files that are owned and maintained by the guests. They would be held on secondary storage in a portable computer, mobile device or camera or held on a network-attached-storage device.

Examples of these include music and image collections held on a notebook computer or just-taken digital images and movies held on a camera, camcorder or mobile phone. This could encompass content that is offloaded to a compact NAS device like Thecus’s N0204 “pocket rocket” NAS.

Property-local media pool

This media pool represents all media available to the guests courtesy of the hotel. It would typically be held on servers located within the property and the most obvious application would be those pay-per-view movies that guests can buy and view on their room’s TV.

But it can encompass any “broadcast-to-network” feeds used for distributing regular, cable or satellite TV through the building via the LAN or line-level media feeds used to pipe audio or video content from cabarets, conference suites or similar locations around the hotel.

Global media pool

The global media pool is representative of media that is owned by third parties and held on servers accessible to the hotel via Internet. The guest would simply select the content from the service provider and have it appear on their TV.

Examples of this would include IPTV services; Internet radio; online-media services like catch-up TV,YouTube or Netflix; the Social Web or cloud-driven remote access to one’s home media pool like Skifta.

A distinct logical realm of control

The room or apartment where the guest stays has to be seen as a distinct realm of control for the guest. This also includes situations where two or more rooms or apartments are hired by the one guest to be used effectively as one room, such as the common “connecting rooms” setup.

This means that the guests have to be able to push the media they want to view to any of the DLNA-compliant devices in their room, whether they bring the devices themselves or use the hotel-supplied devices. It also means that they have access to all of the content they can use, whether it’s the media on their laptop, the pay-per-view movies in the hotel or content on their Netflix or YouTube subscription.

But they can’t push the content to neighbouring guests’ TVs without invitation nor can they gain access to content pools they aren’t normally entitled to.

Ericsson’s proof-of-concept solution

This is a “proof-of-concept” setup that works on the assumption that there is no Wi-Fi Internet service in the premises and the mobile device is using wireless-broadband i.e. a 3G data plan for its Internet.

The hotel will need computer equipment on its network that performs the following functions: a Residential Gateway which links the hotel network to the Internet; and a Residential Control Device which controls access to DLNA devices in the guest rooms or apartments.

The guest’s smartphone will need a handler app which is part of the process of establishing the relationship between the mobile devices and the room devices and is performed whether the Internet connection is via Wi-Fi or wireless broadband. This app maps the DLNA equipment in the hotel room to the “global media pool” available through the online media service based on a unique identifier which is generated when the guest checks in for their hotel stay.

This identifier could be obtained by the handler app through a QR or similar code that is shown on the room’s TV screen when the guest enters the room; or printed on the room keycard that the reception staff hand to the guest. A phone capable of working with near-field-communication setups could obtain the identifier through this path, again at checkin or when the guest lets themselves in to their room if the room lock uses NFC technology; such as some of the newer VingCard RFID setups.

Then the handler would list out the DLNA devices in that room as “content sinks” for the guest to enjoy their content on.

Missing Factors

In-house public Wi-Fi

There is a missing factor with the Ericsson proof-of-concept setup. Here, most hotels will want to provide Wi-Fi Internet service as a value-added or extra-cost amenity. As well, all smartphones and tablet computers have integrated Wi-Fi wireless functionality.

The typical way of provisioning Wi-Fi in the hospitality industry is to implement a site-wide public Wi-Fi extended-service-set covering the whole of the building. As well, if the public Wi-Fi network is properly setup, there isn’t the ability to link data between the Wi-Fi-enabled computing devices, so as to assure privacy and security for each computer user. I have raised on this site the idea of evolving this secure-network setup further to allow clusters of device

There hasn’t been work done on the idea of implementing a room-unique or guest-unique network setup for the hotel industry. This is although some hotels were trying out the use of “MiFi” routers to provide guest-unique network setups, which I learnt of in an article in the HotelChatter blog; as well as the many Wi-Fi routers that I had seen set up at the Australian Audio & AV Show in the Melbourne Marriott Hotel in order to provide DLNA media networks for demonstrating network-driven music distribution.

Access to local media

Another missing factor is the ability to provide held in the guest’s own media pool to the room’s DLNA ecosystem. Here, we may want access to the media held on our devices, whether it is music held on a smartphone, videos held on a tablet or just-taken images held on our Ultrabook.

Here, there wasn’t any question about gaining access to media held on these devices via the hotel’s public-access network infrastructure either through “pull” (access through DLNA playback device’s controls) or “push” (source device’s control app) methods.

Multiple rooms

The last factor that wasn’t considered is the desire to pass media between rooms of a cluster such as guestrooms hired by a family or a conference room hired by a business alongside the guestrooms for the conference guests as part of a “block booking”.

These multi-room bookings may provide for arrangements like allowing users to shift the content to other rooms under limited circumstances. Similarly, it could be feasible to have content held on one device in one room viewable on devices in other rooms used by the group.

On the other hand, it would be desireable to prevent content being push-played by one group member to the room of another group member as a way to assure privacy and security for that member.

This situation can be catered for using the Residential Control Device software by allowing bridging between the unique IDs under certain circumstances.

What would be essential for successful DLNA setups in the hotel sector

Local logical network serving one or more physical networks

Here, you would need to create a local subnet (logical network) for each room / apartment or cluster or rooms. The physical Wi-Fi networks that are part of this local subnet would need to work with a unique SSID and stay-unique Primary Shared Key for their security. They would be served by a local Wi-Fi router that would be managed by the hotel’s “back end” software.

This software would bootstrap the router so that it is set up to the guest’s needs and allow guest-supplied equipment to simply and securely enter the subnet, linking it to the Internet and the hotel-supplied DLNA equipment. This would be set up with NFC or QR-Code technology or WPS-PBC setup when the guest enters their room.

Upon checkout, this router would be set up to a “ground-zero” mode which doesn’t provide casual access to the Internet or the DLNA devices until another guest subsequently checks in.

A consistent connection and discovery experience

When you connect your computer equipment to this network, the discovery experience for DLNA-compliant equipment must be the same as for when you use your computer at home.

The local logical network can make this feasible by exposing only the DLNA-compliant AV equipment that exists within the guest room / apartment at the exclusion of equipment and computers in neighbouring rooms. Yet the content-discovery experience is what would be expected for the class of equipment. This includes the use of control points to “push” content to playback devices.

IPv6 – a main facilitator

A major facilitator for this setup would be the use of IPv6 networks. The address pool offered by this standard is much bigger than the address pool offered by the legacy IPv4 technology and there is inherent support for secure tunnels between logical networks.

In this application, an IPv6 setup can comfortably create local logical networks for each and every guest room in a large Vegas-class resort or downtown (central business district) hotel. There is no need to implement network-address-translation to permit the local logical networks and the back-end systems aren’t destabilised. There is the ability for IPv6 routers to create v6-v4 links to legacy IPv4 devices which represent most DLNA media playback devices and this has to be supported and functioning properly in these devices.

Conclusion

What needs to happen to facilitate the concept of DLNA-based media management in the hotel environment is for further research and study to take place. Here, it would need to be based on technologies that are currently available to the hotelier and potential guests, such as in-house public Wi-Fi networks and near-field communications.

The functionality could also be implemented in network-infrastructure equipment through the use of software that is deployed to the equipment while it is in use, rather than through replacing or adding new hardware. Any DLNA-enablement setup should not preclude the use of media devices that are available to the consumer marketplace.

I had visited the Australian Audio & AV Show 2011 which was held at the Marriott Hotel in Melbourne over two days. Here I had noticed certain trends being marked out as far as hi-fi and home-theatre technology went.

The old-school of hi-fi lives on with these valve (tube) amps

There was interest in orthodox hi-fi setups where vinyl records or CDs were the main medium of choice. These still appeal to the music listeners who prefer to make a point out of listening to their favourite recordings. Here, there was a large number of amplifiers that were driven by valve (tube) technology which appealed to audiophiles who placed value on the “valve and vinyl” style of hi-fi enjoyment. It even showed that there was still life in the “old girl” that was the classic vinyl record, This was more so with the arrival of newly-issued recordings on what I call “boutique vinyl” i.e. records that were cut for best dynamic range and pressed on heavier discs that were made of new material; with the ability for the purchaser to download MP3s of the same recordings for free.

Marantz CR603 CD receiver

Of course, I had seen the return of Luxman to the hi-fi scene, with their efforts on high-grade CD players and stereo amplifiers, with one of their amplifiers being modelled on a 1970s-era classic of theirs.

Network audio

But the main focus of the show was the use of computer equipment and home networks to play out music through hi-fi systems.

Network setups

A router and DLNA-enabled ReadyNAS is what this show is about

Most manufacturers which were demonstrating network-based hi-fi setups had a small network in their hotel rooms. This typically had a wireless router that was fit for home or small-business use at the “edge” of each of these network and working as the DHCP server; the same as what would be expected for a home network. As well, a lot of the manufacturers hooked a network-attached storage unit like the ReadyNAS to these networks to demonstrate their network-audio equipment.

In some cases, some of the suppliers used computers running DLNA-compliant media server software on the network rather than a NAS. An example of this was NAD who linked a MacBook Pro running Elgato EyeConnect as a media server for their C446 Digital Media Tuner.

Network-audio equipment

NAD c446 Network Media Tuner

Most of the equipment shown was network-audio adaptors which were known by names as “media tuners”, “Internet tuners”, “network media receivers” and similar names. These were components that were connected to existing amplifiers through a line-level connection and could play content on a DLNA media server, USB memory key or Internet-radio services. Some of the units could connect to and control an iPod attached to their USB port.

Some of these are devices that I have cited in a previous article on this site about top-shelf hi-fi names using DLNA as their preferred network-audio infrastructure. Here, I had mentioned about them using this established technology and the high-grade codecs like FLAC so they can concentrate on high-quality clear sound.

Linn Majik DS network preamplifier

Linn had a handful of these devices which worked as control amplifiers for use with power amplifiers or active speakers. These Akurate, Majik and Klimax units could also stream line-level signals or, as I have seen, the output of a turntable (Linn Sondek LP12) playing a record to other Linn network media adaptors.

As well, some of the manufacturers were offering receivers and CD-receiver systems that had DLNA media playback and Internet media access as part of their function set. This included the Rotel RCX-1500 CD receiver that I have previously reviewed on this site. Speaking of which, Rotel’s Australian distributors, International Dynamics are introducing more network-enabled kit from Pro-ject, in the form of another network media adaptor.

Denon even promoted their network-enabled home-theatre receivers a “everyhing”-ceivers because of the multiple functions that they could offer through the home network.

Denon's "everything"-ceiver

All of these setups were based around UPnP AV / DLNA Home Media Networks with Denon, Marantz and B&W demonstrating Apple AirPlay-compliant setups. The sales representatives for most of the various manufacturers had described the UPnP AV / DLNA network setup as an open setup where everyone can “come to the party”. A lot of the setups were controlled using various UPnP AV control points that were running on iPads owned by the various demonstration staff. Some of the control-point apps were branded and optimised for particular manufacturers’ equipment, usually offering control functionality that worked peculiarly with that equipment.

Naim Uniti network CD receiver with Naim's distinct CD-loading tray

Naim and used this show to exhibit their Uniti CD receiver; as well as the UnitiQute network media / FM receiver and the UnitiServer which is their “ripping NAS”. This is a class of NAS which uses an integrated optical drive and software for ripping CDs to the hard disk.

One interesting point that I had noticed was that Loewe had used this event to launch their MediaCenter network-enabled music system. This was equipped with a hard disk and software that allowed you to “rip” the currently-inserted CD to that hard disk, a practice that I had observed with some Philips and other hard-disk-equipped music systems. But this unit was able to share the contents of its hard disk to other UPnP AV client devices as well as become a UPnP AV client device for devices like those NAS units.

How is this becoming relevant to “real” hi-fi?

Loewe Mediacenter media server and player

One reason this is happening is that other Websites, fronted by audiophile recording labels, are offering their recordings for purchase and download as high-bitrate FLAC or, in some cases, WMA files. In some cases, these are copies of the studio-master recordings rather than producer-tuned masters for CD and iTunes distribution.

Here, you could load these files on to a NAS and share them through your network with network media clients of this calibre. Or you could use media-management software to transcode to MP3 for use on most portable players and smartphones or prepare CDs of these files for playback on regular CD players.

Conclusion

What I see of this Australian Audio & AV Show this past weekend is that the home network as a system for storing and playing audio content has earned its stripes as far as high-quality sound reproduction is concerned. This is definitely underpinned through the use of the UPnP AV / DLNA standard for discovering and presenting available media content in these networks.

My comments

Typically, the kind of equipment supplied to consumers by telecommunications carriers and Internet service providers for “triple-play”or similar Internet services has typically been drab in design and functionality. This is typically to work to the lowest-common denominator with both price, functionality and style.

The situation is very different in France where there is a lively competitive market for “triple-play”Internet service. Most urban or regional centres in this country are “dégroupée” for multiple competing ADSL-service operators. Here, these operators have access to the customers’ telephone lines as cable without paying France Télécom for a dial-tone service. There is also a steady rollout of fibre-optic service by the competing service providers for next-generation broadband Internet, with an overlaying requirement to provide competitive access to the ducts and poles for the fibre-optic service.

One of these major players is Free who have established a triple-play service for many years. Their latest iteration of the “Freebox” is now a benchmark for anyone offering a similar setup, whether in France or anywhere else.

I have previously covered the Freebox Révolution  in HomeNetworking01.info when a recent firmware update was released that integrated it with Apple’s ecosystem. As well, I have researched many French and English-language resources to learn more about this system.

The Freebox Révolution system

This system, like other triple-play setups offered in France, comprises of an Internet-gateway device, known as a “box”, and a set-top-box, known as a “décodeur”. These units have typically been interlinked by an Ethernet cable or user-supplied HomePlug kit, but is connected through a pair of “Freeplugs” which combine a power supply and a HomePlug-AV-Ethernet bridge in one box.

The units are a statement of industrial design in a similar way that Bang & Olufsen equipment are still a statement in this regard for consumer audio-video equipment. Both the Internet-gateway device and the set-top box have been designed by Phillippe Starck, known for extraordinary designs like the Parrot Zikmu network-enabled speakers or some of the LaCie external hard drives or network-attached storage systems.

Internet Gateway Device (Freebox Server)

This device consists of a broadband router, network-attached storage, VoIP ATA with DECT base station and audio player in one box.

It has a dual-WAN interface for either an ADSL2 service or an FTTH fibre-optic service. But the LAN functionality is one of the hallmarks of a cutting-edge device. It has 4 Gigabit Ethernet switched ports for Ethernet client devices as well as an access point for an 802,11n three-stream 450Mbps Wi-Fi segment. I mentioned previously that this unit also supports a HomePlug AV segment through the use of the supplied Freeplug adaptors. The Wi-Fi access point can also work as a separate “hotspot segment” for other Free subscribers.

The VoIP functionality works with an integrated analog-telephony adaptor and a DECT base station that you can associate 8 DECT cordless handsets with. These will provide full functionality with CAT-iQ DECT handsets.

The 250Gb NAS can work with the regular file-protocol suspects (CIFS, FTP, HTTP) but can work as a DLNA media server. It also works as a “staging post” for FTP, HTTP and BitTorrent downloads, the latter function being described as a “seedbox”. The recent firmware upgrades also implemented Apple TimeMachine support for incremental MacOS data backups. Of course, there is USB connectivity for 2 devices as well as eSATA connectivity for an external hard disk.

There are integrated speakers for playing media held on the hard disk, the Internet or an Apple AirPlay network but you can use it as an elementary amplified-speakers setup by connecting a Discman or iPod to its AUDIO IN jack. Of course you can play the music through better powered speakers or an amplifier using the AUDIO OUT jack.

This router is totally UPnP to the hilt with UPnP Internet-Gateway-Device for hands-free setup with Skype, games, MSN Messenger and the like; as well as being a UPnP AV / DLNA media server. Free could do better by integrating something like TwonkyMedia which can allow content discovery on metadata other than the file-system tree.

Let’s not forget that the Freebox Server is IPv6-ready as expected for a future-proof device. This is being augmented by the fact that ADSL Free subscribers in zone dégroupée aras or FTTH Free subscribers can have an IPv6 connection now.

Set-Top Box (Freebox Player)

This unit has an integrated Blu-Ray player with Blu-Ray 3D support (after new firmware added) as well as a digital-TV / IPTV set-top box / PVR. It connects to the TV via an HDMI connector or a SCART cable, both offering that “single-pipe” connectivity between the Freebox and the TV. Of course, there are connectivity options for other audio-video setups like SPDIF optical; and you can connect USB peripherals like SD card readers to this unit for direct viewing.

It is controlled via a gyroscopic remote control but has a supplied game controller as an alternate input device. Of course, you can connect a USB keyboard and mouse to it as extra input devices or control it from your iPad using the Freebox Connect app.

One drawcard in my opinion is that it is a fully-fledged Internet terminal with access to an app store, namely the FreeStore app store. This allows you to download games and similar “lean-back” apps; as well as view the Web or check email from your couch. Just of late, this set-top box has had YouTube support baked in to its latest firmware update.

You can now use the Freebox Player and its associated sound system or television’s speaker to play material from your iTunes software or iOS device using AirPlay. This at the moment applies to audio content only.As well, you can discover and play content held on DLNA-compliant media servers on your network including the Freebox Server’s hard disk.

Plans and Pricing

You can equip that French home or apartment with this device for € 29.90 per month. This gives you inclusive unlimited telephone telephone calls to standard phone services in most countries (Europe, Francophone countries, US, Australia, NZ, etc); and mobiles in France.

The Internet service would be up to 28Mbps while you have access to most basic TV service. Pay €1.99/month extra for 185 additional TV channels while you can service another room with Free’s TV service for €4.99/month extra with a simple set-top box or another of this Freebox Player for €9.99/month extra.

Existing Free subscribers can upgrade for €199.99 less €30 for each year they have been with Free.

The prices are obtained from Free’s latest tariff charts available on their site and would appear to be ridiculously low for people who live in a country that doesn’t have a lively competitive broadband-Internet market.

Conclusion

What I see of the Freebox Révolution is a system of equipment for a home network that is all about an Internet service provider offering a future-proof attractive cutting-edge piece of equipment rather than offering second-rate equipment to their customers.

This is primarily driven by a country who is behind a really competitive Internet service market for consumers and that the competition is driven on value rather than the cheapest price possible.

Seeing DLNA. Cool media sharing. by scobleizer

My Comments

This on-demand broadcast is a DLNA-hosted interview that I heard about what the DLNA home media network is all about with its heterogenous benefits.

One key factor that was mentioned many times was the heterogenous nature of the DLNA ecosystem. Here, they illustrated practices like bringing content up from a network-attached storage unit to Samsung TV or a TV hooked up to a network media adaptor from a different vendor using one of Samsung’s Android tablets.

They even cited the ability to use different software like TwonkyMobile or Samsung’s AllShare on the same Android device to do the same task. Even devices like Sony’s PS3 were mentioned due to the ability to discover content hosted on DLNA servers. Other applications that were even raised include delivering pictures to the printer when you want hard copies of them.

Of course, there was a direct comparison to the Apple AirPlay ecosystem which required the use of iOS devices, the Apple TV (or selected AirPlay-compliant devices) as well as content hosted on computers running iTunes for it to work.

Apple users should know that there is software for their platforms in the form of TwonkyMobile or PlugPlayer for their iOS devices and NullRiver MediaLink or similar applications for their Macintosh computers.

Apple May Lose To Android In Device-Based Media Management | Online Media Daily (MediaPost.com)

My comments

As you may already know, Apple has been promoting their AirPlay media-management ecosystem. This was initially known as AirTunes and worked with their AirPort Express plugin broadband router which can connect to speakers or a stereo amplifier for network music playback. Here, you had to use iTunes on your Macintosh (or PC) to play the audio files through this device. This function was gradually extended to iOS devices so you can then play this same media held on these devices in the same manner.

Apple have extended the concept to images and video through the use of Apple TV and licensed the AirPlay concept to other manufacturers that are approved by themselves. It has been recently demonstrated in the latest crop of iPhone TV commercials as a way of saying that “we know best”.

But there is another standard that is more “open-frame” than the Apple AirPlay system. This standard, called DLNA, has been adopted by a larger number of software and hardware manufacturers than AirPlay.

It is a standard that I have stood for because more of the industry is behind it with it working across equipment and software of different manufacture and has become a breeding ground for innovation. Here, I have seen the arrival of network-media playback equipment that works as part of the DLNA ecosystem appear at every market tier, including the premium-audio segment, with B&O offering a trendy stylish DLNA-capable network music system that puts the Sonos on notice for example. But my stance on this issue may be considered as being of concern to Apple or some of their fanbois who value the Apple-centric information-technology setup.

Equipment like the Sony CMT-MX750Ni music system or the Western Digital WDTV Live that I have previously reviewed can play media content that is “thrown to” it by software like TwonkyMobile on your tablet or smartphone. This is in a similar way that you would do with the AirPlay setup on an all-Apple system and is capable of being performed on an Android platform as well as the iOS platform.

An issue that is forgotten about in the Apple hype is that some third-party companies have written DLNA-compliant media-management software for the iOS devices and the Macintosh platform. Examples of this include PlugPlayer and recent iOS ports of TwonkyManager. As well, I known of a friend who is running NullRiver MediaLink on his iMac in order to use it as a media server for his Sony PS3 games console and he has had success with this setup.

Introduction

I am reviewing the Sony CMT-MX750Ni Internet-enabled micro music system which is a small-form-factor CD/iPod stereo that can connect to the home network for Internet radio or DLNA-based music playback. It is equipped with a DAB+ digital-radio tuner but there is a version of this system known as the CMT-MX700Ni which doesn’t have this tuner and is available in areas that don’t have Eureka 147 DAB / DAB+  digital-radio services.

From henceforth, I am directing the comments in this review also at the Sony CMT-MX700Ni music system as well as this CMT-MX750Ni, except for any DAB digital-radio comments.

Setup and Connection

The CMT-MX750Ni can connect to a network either via Wi-Fi wireless or Ethernet. This allows for flexibility with wired and wireless network setups, such as working with highly-reliable Ethernet and HomePlug networks. You need to use the remote for setting up the music system on a Wi-Fi network that doesn’t use WPS push-button setup. Here, you use the numeric keypad on the remote to enter the WEP or WPA passphrase for your wireless-network segment in an SMS-style manner.

Sony has “reinvented the wheel” when determining how the speakers should be connected to the main unit. Here, they have used a proprietary Molex-style plug at the system end of the speaker cords like they have done with their DVD home theatre systems. Personally, I would prefer that they use a two-conductor 3.5mm phone plug, or the older 2-pin speaker-DIN plug, both of these connections can allow for easier-to-replace, easier-to-modify speaker connection. Infact a lot of the music systems that were sold through the 1970s and 1980s with supplied “separate-piece” speakers, such as the “detachable-speaker” boom-boxes have used either the 3.5mm phone plug, 2-pin speaker-DIN plug or RCA plug to provide “plug-in” speaker connections and these have just worked as well for plug-and-play operation.

The speakers are a typical bass-reflex two-way setup but aren’t aggressively styled. One thing I am pleased about these speakers is that they are well-built and the enclosures use an all-wood construction rather than a plastic front baffle which shows the quality behind the system.

In use

You have the ability to perform basic content-navigation tasks using the controls on the Sony CMT-MX750Ni’s front panel but you need the remote control to use this music system to the fullest. The system uses an “Inverse” LCD display as its display. This yields readable text but Sony could implement a monochrome OLED or fluorescent display rather than the LCD which makes it look “cheap”.

Other than that, when you operate the Sony CMT-MX700Ni or CMT-MX750Ni music systems, you find that you are operating a well-built music system. The switches and mechanisms don’t exhibit any sort of tackiness that can be noticed in a lot of bookshelf music systems. The remote control is relatively large and with it you have one-touch access to the sources and main functions as well as being able to do advanced functionality.

The FM tuner didn’t perform properly on the “pigtail” aerial that was supplied with the unit, especially as it was on the lower level of a split-level house. Here, I would recommend connecting it to a better FM aerial like an outside one if you want the radio to work properly in a difficult scenario.

This setup didn’t challenge the DAB tuner with it able to survey the DAB+ multiplexes in Melbourne and provide clear and reliable reception from any program on these multiplexes.

The CMT-750Ni and CMT-700Ni use an iPod dock that drops down from the front panel. This makes it easier to hide the dock if you are not using an iPod or iPhone with it. As well, the iPod or iPhone can lean against the front panel while plugged in without the need to use any dock adaptors. The only limitation with this is that you need to pull back a hard-to-discover latch before you can close the iPod dock.

The front-panel USB socket allows you to play music of a USB memory key, SD card adaptor or smart phone. But it is “live for power” only when system is in operation and supplies the power when you select other sources so you can charge up your Android smartphone or other USB-connected device. This situation is similarly true for the system’s iPhone dock and it could be tempting for users to dock their iPhone in this CMT-MX750Ni’s dock in order to charge even if the system is not playing. It could have the option to supply power to charge devices connected to the USB socket or iPhone dock even when the Sony music system is in standby.

When the Sony CMT-MX750Ni or CMT-MX700Ni plays Internet radio and loses the connection to the station, it doesn’t try to reconnect to the station unlike the other Internet radio products I have used. Here, it just goes back to the main menu and you have to retune to that station, and this can be annoying with over-subscribed Internet streams. Other than, the Internet radio experience works properly as best as the link can allow.

This system works as an audio device in the DLNA Home Media Network. This includes the ability to play audio content that is “pushed” to it from a DLNA-compliant control point like Windows Media Player or TwonkyMedia Controller. It serves this function properly whether you pull the content up using the unit’s control surface or push the content out using a DLNA control point.

These music systems can work in the “Party Streaming” mode where multiple Sony receivers or music systems connected to the same home network can stream the same content at the same time. The CMT-MX700Ni or CMT-MX750Ni systems can work as either a host or a client system in this aspect.

Sound Quality

There is the ability with these Sony music systems to adjust the tone of the sound system. This can only be done using the remote control and you have to press the EQ button on that controller. Here you have access to bass and treble adjustments but you can also enable a “Dynamic Sound Generator” mode using a separate button. This may add “extra bite” to some recordings but may not yield difference with other recordings and may be about providing “big speaker” sound out of small speakers.

The sound quality is typical for a high-end “micro” form-factor music system but can clip or sound “muddled” around just near the maximum volume point. I have observed this with recent popular RnB music which is tuned for a loud sound with excessive bass but It can “go loud” on recordings that weren’t tuned “loud”, although I have had the CMT-MX750Ni run at “flat” tone settings.

I even ran this system on a DAB+ broadcast of an ABC Radio National program and had noticed that the speech from the show’s presenters came through very clear, crisp and intelligible. This didn’t matter whether it was a man or woman speaking in the show.

Limitation and Points Of Improvement

The “pigtail” aerials (antennas) supplied for DAB and FM use are inadequate for reliable FM or original-specification DAB digital radio (UK, Denmark, etc). As well, these supplied antennas remind you of using the typical clock radio which has this kind of FM aerial and are out of character with this system’s class. It could do better with a “whip-style” aerial similar to what is used for the Wi-Fi network connectivity and could support “single-input” aerial setups through an option.

Other connectivity improvement that It could also benefit from include having a pair of RCA line-input connectors or a “tape-loop” set of input and output RCA connectors on the back of the system for whenever you connect a computer, tape deck or other piece of audio-equipment in a semi-permanent manner. It can also benefit from a headphone jack for private listening purposes. Similarly, it could also benefit from integrated Bluetooth A2DP functionality so it can work with phones and media players that use this medium as a way of transmitting music data.

iPod dock with fiddly latch that needs to be released to close it

I would also improve the iPod dock so that you don’t have to operate any latches to open or close the dock. As well, I would provide the ability to charge smartphones connected to the USB socket or docked in the iPhone dock while on standby as a user-selected option. This can allow the user to keep an iPhone or other smartphone “topped off” when docked or connected to the system.

Another point of improvement would be to allow the CMT-MX750Ni music system to retry Internet-radio streams if the stream it is tuned to “gives up the ghost”.

I would also like to see the Internet-media and home-network-media functionality implemented into most of Sony’s bookshelf-stereo range and / or for Sony to develop a network-connected CD receiver along the same lines as the Rotel RCX-1500 CD receiver I previously reviewed.

Conclusion

I would recommend purchasing the Sony CMT-MX750Ni or CMT-MX-700Ni network-enabled music systems for use in a small room like a bedroom, den or office. It may work well for use in an apartment’s small living area.

On the other hand, I wouldn’t use this music system in situations where it is expected to fill a large room with music or play in a noisy area like a party or cafe.
