Interview Series–Network audio and video

Introduction

Between the end of October and the beginning of November, I had a chance to interview people who work with two different companies that work in the consumer audio-video market and had noticed some trends concerning this market and its relevance to the online world.

One main trend was that there was increased focus by consumer-audio manufacturers who work in the popular marketplace on delivering DAB+ digital radio equipment rather than network-connected audio equipment to the Australian market. This may be because some of these firms need to see this technology become more popular here and want to have “every base covered”.

Sony

From my interview with Kate Winney I had observed that Sony had a strong presence in the connected-TV scene. Here, this was more concentrated with their newer “main-lounge-area” TVs but they are providing this functionality on some of their video peripherals, namely their BD-Live Blu-Ray players.

We agreed that Sony had no Internet radio in its product lineup although they implement Shoutcast on their high-end home-theatre receivers like the STR-DA5500ES. But we agreed that they need to make DAB+ available on their stationary “big sets” like hi-fi tuners, receivers, home-theatre-in-box systems and bookshelf audio systems. They are releasing a few DAB+ sets but most likely as stereo systems rather than as portables or components.

I had stressed to Kate about Sony implementing vTuner or a similar directory-driven service which is implemented in most Internet radios. This is because most of these services offer access to the simulcast streams of the government, commercial and community radio stations broadcasting to local countries around the world as well as the Internet-only streams of the kind that Shoutcast offers. It is also because most people who are interested in Internet radio are likely to want to use it as a way of enjoying the “local flavour” of another country that is provided by that country’s regular broadcasters rather than just looking for offbeat content.

Kate also reckoned that DAB+ digital radio needs to be available in the dashboard of cars in the new fleet, preferably as standard equipment or as a “deal-broker” option offered by car dealers for the technology to become popular. I was also thinking about whether Sony should offer DAB+ technology as part of the XPLOD aftermarket car-audio lineup.

Bush Australia

From my interview with Jacqueline Hickman, I had noticed that Bush are still focused on implementing DAB+ digital radio in Australia but are using Internet radio as a product differentiator for their high-end “new-look” sets that are to appeal to young users

Their market focus for consumer audio is on the “small sets” like table / clock radios, portable radios, small-form stereo systems but I have suggested implementing or trying some value-priced “big sets” as product ideas. This is even though they run some “main-lounge-area” TVs and digital-TV set-top boxes in their consumer video lineup.

The ideas I put forward are a DAB+ or DAB+ / Internet-radio tuner that is for use with existing audio equipment and a FM / DAB+ (or FM / DAB+ / Internet-radio) CD receiver with optional speakers. A market that I cited are the mature-aged people who own “classic hi-fi speakers” from 1960s-1980s that they like the look and sound of but may want to run them with a simpler cost-effective component. I had made a reference to the “casseivers” of the late 70s and early 80s which have an receiver and cassette deck in one housing and what these units offered. Jacqui had reckoned that companies like B&O and Bose filled the market but I have said that some of the companies have gone to active speakers rather than integrating power amplifiers in the equipment. As far as the DAB+ tuner is concerned, she suggested that a person could use a portable DAB+ set and connect it to the amplifier using an appropriate cable.

I raised the topic of IPTV but Jackie was not sure whether this will be implemented in any of their TV sets or set-top boxes at the moment. This sounds like a product class that hasn’t been properly defined with a particular standard and platform especially in this market.

Conclusion

It therefore seems to me that there is more interest by consumer-electronics companies in nurturing the DAB+ digital radio system and the DVB-T digital TV system because they are based on established technology and established metaphors; and appeal more to “Joe Six-Pack” than the Internet-based technologies.

Also, I had noticed that it takes a long time for all equipment classes to benefit from a new technology. This is more so with DAB+ digital radio and, to some extent, Internet radio where the mains-operated stationary “large sets” like hi-fi equipment and stereo systems are under-represented.

Windows 7 – What does it mean for multimedia and the home media network

Improved sound-reproduction infrastructure

Some of you may use two or more sound cards in your computer; such as using the sound circuitry that is part of your motherboad as well as an aftermarket sound card. Windows 7 caters for that by allowing you to relegate a particular sound subsystem to a particular program or activity. A common use would be to use a Bluetooth headset for Skype and related VoIP communications, gaming taunts and similar applications while you have your music playing through the main speakers. Similar you could connect a “good” sound card to a good sound system for recording and playback while the onboard sound infrastructure can be used for system sounds.

Even the ability to send digital audio signals to home-theatre equipment via the HDMI port has been improved. It includes the ability to pass the high-definition audio streams from BluRay and similar applications as a raw bitstream. It will also provide the multiple-sound-device functionality as mentioned previously with HDMI audio setups that use a dedicated sound infrastructure rather than feeding an SP-DIF audio bitstream from the computer’s main sound card.

As well, there is functionality that permits the music or video sound to be reduced in volume whenever a VoIP or similar call comes in even if the call goes through a different sound device, which makes life easier when you take these calls using the computer.

DirectX and Gaming

DirectX in Windows 7 has been taken up to version 11 and this has brought forward a lot of improvements as far as computer games go. This also includes a lot of work “under the bonnet” to improve game responsiveness with the screen and sound and bring up PC gaming to current-generation console level.s

Streamlined network management

The network management functions are similar to what Windows Vista users have expected in the Network And Sharing Center, But this interface has been streamlined and made easier to use. The “full map” is still available and you can gain access to shared resources or UPnP-provided device management pages when you click on the various devices.

HomeGroup

This feature is a way of establishing a “circle of trust” within a home network when it comes to sharing resources around that network. This is based on a computer-generated password that is used across the HomeGroup to authenticate all of the computers on the network to the resource pool. At the moment, this only works across Windows 7 boxes on the network, but it may be worth keeping an eye out for Microsoft and third-party downloads that allow Windows 2000 / XP / Vista, Macintosh and Linux boxes to work in with a HomeGroup setup.

This is another way that Microsoft implemented a practice commonly associated with locks and keys, Here, the identifying factor that only allows the lock to work with particular keys is already determined by the tumblers that are integrated in the lock’s mechanism and these tumblers are configured to work that way either by the manufacturer or by a locksmith when you have the lock rekeyed.

The first instance of this was with Windows Connect Now, which was implemented in Windows XP Service Pack 2 as a way of configuring a highly-secure wireless network. Here, the WPA-PSK passphrase was determined randomly by Windows Connect Now and used as part of a “configuration manifest” file to be transferred to routers and other computers using a USB memory key. This was extended to Windows Vista through the WPA-PSK passphrase being uploaded to a compliant wireless router using an Ethernet connection, and was integrated in to Wireless Protected Setup which is implemented as part of Windows Vista Service Pack 2.

Another advantage provided with HomeGroup is that it can work with “work-home” laptops that move between a domain-managed business network and a home network. HomeGroup can also cater for other small networks, because there is the option to share particular resources with particular users as you were able to do son with any Windows-based CIFS network.

Improved DLNA support

Windows Media Player 12, which is part of the Windows 7 distribution or, in some cases, available as a free download from Microsoft, has DLNA built in to its ecosystem. This doesn’t just stop at sharing media files with DLNA / UPnP AV media devices or streaming media files from other DLNA / UPnP AV media servers like NAS boxes. It allows you to “push” content to DLNA / UPnP AV media devices that present themselves as “MediaRenderer” devices. This is typically provided in the form of the “Play To” right-click shortcut for multimedia files.

Remote Media Streaming

You can stream content from one Windows 7 computer to another over the Internet as long as you use the same identifier, like a Windows Live ID. with each of them. This can be useful for situations like temporary accommodation like hotels, holiday homes or serviced apartments where you may have your computer at home running and you may want to play media at your temporary location. I have discussed this feature before on this blog and have raised issues regarding VPN operation and the computer that is pulling the media being able to serve it to DLNA-compliant media hardware on its local network.

Inherent support for current digital-TV standards and Internet TV

Windows 7 provides its Media Center application with inherent operating-system support for currently-deployed digital-TV standards so there isn’t much need for TV tuner card manufacturers to supply software to work with the current standards. As well, this operating system provides improved support for “over-the-top” Internet TV services that may be released in your country. In some cases, this may do away with the need for the coaxial TV cable to the computer or the need to sign up to cable services full of “fodder channels” to gain access to the “good channels”.

Next article in the series will touch on how Windows 7 will benefit the small business and the work-home laptop.

 Quatre ans de DegroupNews : et les FAI dans tout cela ? – DegroupNews.com (French language article)

My Comments

Congratulations DegroupNews on 4 years of service as one of the better IT newsblogs that service France.

I have been a fan of this site and its companion DegroupTest site because of the good quality information that these sites give about the Internet-access scene in France. This includes information on the arrival of Fibre To The Home broadband service in various French cities as well as the service being used for a “people’s triple-play service” which provides receive-only VoIP telephony, basic-ADSL-tier Internet and IPTV service encompassing free-to-air digital TV for one euro a month.

For people who are considering moving to France or setting up or maintaining that dreamy farmhouse or apartment there as a holiday house, rental property or “bolt-hole"; this site offers good quality information on the triple-play “n-box” deals offered by the main operators as well as information about whether you can get a full triple-play Internet service at the location where your property is or will be. It has also made good-quality reviews of the hardware provided by the various Internet service providers as part of their deals so one can know what to expect when signing up.

Other issues that have been touched on in this site include the way the French have handled the perceived cancer demon associated with wireless services like mobile telephony and WiFi networks; as well as their handling of the file-sharing of copyrighted works. It is worth a read whether you have a good grip of the French language or can trust a machine-translation service like translate.google.com to translate the site in to your own.

"Triple Play Social" now in full deployment in Paris

News Links (French-language sites)

http://www.degroupnews.com/actualite/n3071-hlm-paris-sfr-fibre_optique-haut_debit.html DegroupNews (France)

My commets

Since my earlier article wbich I had moved from my older blog, SFR had taken over Neuf Cegetel. But this universal-acces “single-pipe triple-play” service has continued on and the trucks are now rolling a the HLM estates as this is being written.

Because of the high-throughput technology, companies like SFR are able to provide this kind of acess to the people.  As I mentioned earlier, it is underpinned by the European business culture which is primarily “for the people” rather than for the executives of the big companes which is the primary business culture in the USA.

"Triple Play Social" in Paris – an example for providing a universal bare-bones "triple-play" service

News Links (French-language news sites)

My comments

)In February 2008, Neuf Cegetel (a French telecommunications provider) along with Office HLM de Paris (the public housing authority in Paris, similar to the Ministry of Housing in Victoria, Australia) have established a universal-access “single-pipe triple-play” service for deployment in areas of Paris that have fibre-optic telecommunications.

This service, which is offered for EUR1 / month tax-exclusive has the provision of:

  • 18 channels of regular “free-to-air” digital television programming including high-definition broadcasts provided by the “free-to-air” broadcasters
  • 512kbps broadband which is effectively the same standard as most mid-tier ADSL plans currently available in Australia and;
  •  a landline telephony service of similar standard to Telstra’s InContact service — can receive incoming calls but cannot make outgoing calls except to emergency and special numbers

delivered over the fibre-optic pipe.

Comments on this service in relevance to the Australian market

From what I see, the 512kbps ADSL service is being considered the bare minimum standard of Internet access in Europe where people in Australia have to call this standard of service a luxury and have to consider 256kbps “fraud-band” Internet service as the “way in” when thinking of broadband. Often this has meant that sole parents and others on very limited income are having to stick to this speed if they want to think of broadband at all; or just simply work with a dial-up Internet connection.

As well, Australian pay-TV providers don’t offer a “FTA-only” deal where you only receive the free-to-air digital TV channels. This may be because of the prevalence of cheap standard-definition DVB-T boxes flooding the market and the DTV service comprising primarily of the FTA channels receivable on regular TV and a handful of supplementary channels that are “spin-offs” of the regular broadcast output. The only areas where such a service may take hold would be customers who live in areas with marginal TV reception and / or customers who rent premises where there is an underperforming TV aerial or simply no TV aerial and may find it hard to get proper digital TV reception.

The kind of landline telephony service that is offered may appeal not just to people on a low income but to share houses where a common telephone may be required just for receiving calls and “emergency fallback”. Typically, the tenants would then maintain prepaid mobile phones for their outgoing calls and for receiving personal calls.

This kind of service provisioning may catch on in Continental Europe where most of the culture is centred around being “for the people” but won’t easily be accepted in cultures like the USA where corporate profits are more important than the needs of the people.

General-sale digital-TV set-top boxes and DLNA

At the moment, most add-on “over-the-air” digital-TV converter boxes sold through general retail don’t come with UPnP AV / DLNA media-client functionality. But this feature could be offered as something to differentiate units in a product line or differentiate a unit from one offered by a competitor.

There will be a lot of interest in these boxes over the next few years as various countries either switch off analogue TV service and go “all dgital” or enrich their digital-TV platform. This is espeially so as people want to make sure that they can receive the digital TV service on other TVs in their house and at other locations. Integrating the DLNA functionality in these set-top boxes can allow the boxes to become two devces in one – a network media adaptor as well as a digital-TV set-top box.

It will then work with Internet TV / vodcast gateway software that provides DLNA-based directory software for Internet TV services and vodcasts, thus allowing access to this kind of content on the regular TV. The same could hold true for any multimedia content held on a PC or network-attached storage connected to the home network.

Similarly, this concept can work with DLNA-compliant PVR set-top boxes and provide access to content that is recorded on the PVR unit. It can also provide access to “multi-room PVR” functionality like the ability to pause a show in one room and pick up where you left off in another room. Such functionality has been provided for in version 2 of the UPnP AV MediaServer and MediaRenderer device specifications.
