NAB: New 5.1 Extension Means Better Compression

Dolby Laboratories have announced an extension to their Dolby 5.1 codec, called Dolby Digital Plus. The codec extension is of particular interest to television broadcasters because of the efficiency of its compression: if audio tracks take up less room, then it leaves more bandwidth for more channels.

Broadcasters are keen to deliver more channels to customers – particularly when they’re charging them – but need to keep picture quality up to, or even better than, current standards.The existing DD codec supports but rates from 320Kbps to 640Kbps for 5.1 audio – yet this new extension will reproduce 5.1-channel sound down to 192Kbps. Dolby Digital Plus has a new top end to – up to 6Mbps, which will no doubt be handy in the future.

Importantly, Digital Plus is backwardly-compatible with previous versions of the 5.1 codec.

Dolby have already come up with an interesting application for the new codec – a DVD could access a studio’s website and stream a live director’s commentary, or other interactive content, through the viewer’s TV.

NAB: USDTV Chooses Windows Media 9 for Pay-TV

We covered USDTV a few weeks ago when they launched the first digital over-the-air digital TV service in the USA. Since then, they’ve been making further progress, and have just joined up with Microsoft for another first: delivering HD programming to subscribers using Window Media 9.

They plan to implement WM9 by Q4 this year when they launch a second generation set-top box, which is expected to feature that increasingly common component: a big hard drive.

“Maximizing available bandwidth with Windows Media 9 Series will allow more broadcasters, especially network affiliates, to participate with USDTV,” said Steve Lindsley, Chairman and Chief Executive Officer of U.S. Digital Television, Inc. “This will enable us to bring more content variety to viewers and create additional revenue-sharing opportunities for broadcasters.”

“Windows Media 9 Series enables USDTV to expand their programming and reach new audiences,” said Amir Majidimehr, General Manager of the Windows Digital Media Division at Microsoft. “Windows Media has approximately three times the compression efficiency of MPEG-2 and easily scales up to high definition (HD), delivering HD at what would normally be considered SD data rates.”

Channel 4 Planning New Digital Services

Channel 4 is planning some new digital services in the UK to retain and grow its share of viewers. It has not been confirmed by Rob Woodward, commercial director of the company, if the new channels will be free to air or subscription only, but they are expected to cover music, factual and comedy. They’ll be carried on Freeview, that much is certain.

The new channels may be aimed at an older ABC1 audience (i.e. a bit more BBC2) than C4’s current younger mainstream audience.

More details when we have them.

Japan Agrees on Digital Terrestrial TV Standard… for Mobile Phones

Japan’s six major television networks have agreed a standard for broadcasting and receiving digital television for mobile phones.

Fuji TV, NHK, NTV, TBS, TV Asahi and TV Tokyo have all signed up for the standard. “I think this will raise awareness among viewers about digital broadcasting and we hope it acts as a spur,” TV Tokyo managing director Katsumi Ueda told a news conference.

Services are due to start in April 2005, and will be free – but as yet, no handset or network providers have signed up. Interestingly, NEC released a prototype mobile phone that was compatible with Japan’s existing digital TV standard, but it suffered from power problems. See our recent article on DVB-H, linked below.

USDTV Launch USA’s First Over-the-Air Digital TV Service

It’s a broadcast model that’s been available in the UK for a while, but US Digital Television (USDTV) have introduced a digital TV service employing unused digital spectrum leased from its broadcast partners.

The subscription to the service is US$19.95 and includes channels from Fox, Disney and ABC. The set-top box to receive the broadcasts are made by Chinese manufacturer Hisense, and will set viewers back a reasonable US$99.

USDTV promise better picture and sound over analogue cable – and many of the broadcasts will be in HDTV too.

The service is currently available in Las Vegas, Albuquerque and the Salt Lake City Metro Area but is set to expand into an additional 30 areas by the end of 2004.

USDTV recently arranged US$8.5 million in private equity funding from NexGen Investments and Stonebridge Capital – and if they deliver on a number of prerequisites investors say they’re in line for an additional $12 million in funding.

Half of UK Homes Now Receive Digital TV

With penetration of 50.2% of UK households, the total number of homes in the UK watching digital television now stands at 12.3 million, up 423,000 in Q4 2003. This number includes 3.2 million free to air digital viewers using Freeview and ITV Digital boxes, and PC cards.

The report will be submitted to the secretary of state for culture, media and sport at the end of March.

Scientific Atlanta Planning Games Console

In what’s beginning to become a crowded market, Scientific Atlanta have announced that they are working on a games console. No specifications have been released yet, but the company claimed the device could compete with current games consoles from Sony and Nintendo. Chief Executive James McDonald said their new product would offer “the same performance you get out of those game boxes.”

Scientific Atlanta do not expect their Explorer hardware to be available to buy on the high street but will instead be installed by cable operators in subscribers’ homes. Games will then be downloaded to the box on a pay-per-play or perhaps a “buy outright” charging scheme.

Set top box builders and suppliers are working on ever more sophisticated hardware to compete for the coveted space under your television – getting the most compelling media gateway into millions of homes is worth a lot of revenue.

It will be interesting to see how the new console compares with Infinium Labs’ notorious Phantom console, summarised here a few weeks ago. What content will be available for Scientific Atlanta’s new console? It’ll need a lot of software to be able to compete with the systems already in the market, and with the potentially huge library of adapted PC games available to the Phantom.

Also allegedly about to emerge is the DISCover Console – a PC based system that boasts of the simplicity of a console. It allows users to play games simply by dropping the disk in the DISCover’s drive, rather than having to install and configure each game. The DISCover may cause problems for both Infinium and Scientific Atlanta based on the technology they eventually use: their website claims “‘DISCover® technology is protected by U.S. Patent No. 5,721, 951: a “home entertainment system for playing software designed for play in home computers.’ No one can manufacture a game console that plays PC games without infringing on this patent.”

BSkyB Announces Next Stage for Sky+

The Sky+ personal video recorder is set to evolve under new plans from BSkyB: they want to transform the PVR into a video and audio jukebox that subscribers can download films and music to.

Other plans include integrating five separate tuners – a move which will allow subscribers to record four channels simultaneously whilst watching a fifth.

Sky are also working on a technology that will allow Sky+ users to download content from their set top box to their portable video player so they can watch recorded programming whilst out an about.

Sky hopes to make £400 from each subscriber per year by the end of 2005. By building new functionality into their Sky+ product and then charging on a service by service basis, they should be able to earn significantly more revenue per customer, on top of the basic £15 subscription fee.

Since most domestic users are unlikely to ever want to record four separate programmes whilst watching a fifth, it seems to Digital Lifestyles that BSkyB will probably use this new capability to download films and programming to the PVR automatically, to a dedicated area of the hard disk. This will then allow Sky to promote the programming and offer it to to subscribers on an impulse buy, pay-per-view basis.

New Sony Products Shown at Open House

Sony’s Open House event this year covered all the key consumer devices – from HDTV recorders, and new Handycams to extremely desirable PDAs with more bells and whistles than a bus load of Morris dancers crashing into a flute factory.

Sony are going for integration even more than usual – HDTVs have integrated card readers for cable users, Clié PDAs and VAIO notebooks feature even sharper cameras and better wireless access than before, and MP3 support filters into products where there was previously only ATRAC.

Telewest Float Surf & Sniff Smell Generator

It being Friday and we thought we would bring you a light-hearted piece.

UK cable company, Telewest, has suggested that they may release a computer add-on that generates aromas that can be controlled software. Sound like an urban myth/joke, but it is not without precedent. The first time a computer-controlled device was suggest was in 1999 by a start-up called DigiScent. Prior to that it was on the grander scale of whole cinemas, when in the last 50’s two similar ideas, AromaRama and Smell-O-Vision, were introduced to US cinemagoers.

AromaRama used the theatres ventilation system to get their scents out and Smell-O-Vision far more expensive approach was to place units under each cinema seat.

DigiScent was a serious, scientific approach to the subject that was started by two Stanford graduates that had made some serious fortunes from software for genetic databases.

One of the founders, Joel Lloyd Bellenson looked into previous scientific research around the subject to discover how humans perceived smells. His explanation was detailed in an article by Wired at the time.

“The explanation for this proved relatively simple. When odour molecules drift into the nose, each of them binds with a particular protein on the surface of a neuron. There are about 1,000 odour-matching proteins, each with a slightly different configuration, scattered across a human’s 10 million odour-detecting neurons. (By comparison, a mouse has about 1 million neurons of this type, while a pig boasts 100 million.) When the shape of an odour molecule matches the shape of a protein, the molecules lock together, triggering the neuron, which sends a signal that the brain recognizes as a smell. DNA is relevant because its instructions – its genes – tell the body how to build the proteins that receive odour molecules and activate the neurons. ”

Calling on his previous software experience, Bellenson wrote software to simulate the binding of odour molecules with proteins. By using this he felt he could generate billions of odours simply by selecting different proportions of 100-200 “scent primaries.”

DigiScent’s business was to licence its software to the creators of  other media, to synchronise aromas with them. Web pages would be able to trigger them, as would TV shows, video games and films. The scent generators would be plugged into the serial port and sit on the desk – Reekers, instead of speakers.

Like many ideas around 1999, sadly DigiScent is not around anymore. One possible reason for that could have been is the name they chose for their product – iSmell.

Telewest say they have tested the idea in their labs, calling email using the device ‘ScentMail’, or on a wider scale, ‘Aromanet’. They plan to bring out a domed device that plugs in to the serial port of a computer or set top box, that takes dispoable cartidges to generate the aromas. They say the intial range of smells will be around 60 by mixing the palette of 20 oringial aromas.

Appearing to be designed to get them a few column inches for their broadband service, it is not clear how serious Telewest are about it. When discussing the cost of the dome they are less than exact, ‘Hardware for a surf & sniff set up might cost around £250 for the basic equipment’. We are sure Telewest is not trying to create news during the time their managing director, Charles Burdick, has left the company to “pursue other opportunities.”
