Transmeta hasn't said a whole lot about performance, and I'm not sure I trust a company that tells you not to trust the standard benchmarks,” said Nathan Brookwood, an analyst at Insight 64, a Saratoga, Calif., consultancy.

Set-tops and Internet appliances are no longer a niche solution. They have grown in significant volume, providing serious alternatives to PCs,” he said.

Indeed, many in the industry believe that digital appliances for a diverging market — particularly those using MPEG-2 encoding/decoding features — will continue to proliferate.

Cahners In-Stat Group, for example, predicted in its latest report that the revenue for both MPEG-2 decoding and encoding circuits will double from $1 billion to $2 billion, with units surging from 77 million in 1999 to 200 million by 2004. The Scottsdale, Ariz.-based market research firm noted that STMicroelectronics, among a number of key players in the market, again captured the top spot in MPEG video chip revenue. The company's top position was due to shipments of their integrated MPEG-2 decoder solutions for set-top boxes.

For the diverging TV market, STM is launching a new TV platform based on the company's ST20 32-bit CPU, according to Jean-Yves Gomez, digital TV director at STM. The platform is designed to cover everything from digital-TV-ready analog TVs to all-digital TVs that range from the low to the high end. It will allow system vendors to reuse software while giving them the option of adding or deleting features. The goal is to develop a number of derivatives — based on the platform — very quickly,” said Gomez.

Philips Semiconductors in Eindhoven, the Netherlands, has also adopted a platform” approach like STM's for the digital TV market. More than a year ago, the Dutch company outlined a DTV platform with a MIPS-based architecture and offered the TriMedia multimedia processor as an option for adding flexibility to the overall system.

Broader appoach

Gomez said, The difference from Philips' approach is that our platform covers a much broader range of TV sets, including digital-TV-ready analog TVs.”

Sitting at the core of STM's road map is the CTV100, a digital-ready,” low-cost solution based on the ST20 processor. The CTV100, slated for fabrication by the end of this year, offers improved processing for image and graphics quality. The solution runs at 100 Hz and features advanced teletext, on-screen display and bit mapping, and a digital chroma decoder.

The CTV100, meanwhile, can be quickly turned into a full digital TV solution, called DTV1, according to the company. The DTV1 consists of an Omega TV1 chip, also based on the ST20, and a digital chroma decoder used in the CTV100.

China is a perfect market for CDMA, and it makes business sense for China Unicom,” said Perry LaForge, the executive director of the CDMA Developer Group (CDG). It [gives] Unicom technical leadership in this region. It also [gives] domestic manufacturers more opportunities.”

CDG, a nonprofit trade group formed to promote the development and use of the cdmaOne spec, was the co-organizer of the CDMA conference.

Political role

Despite the optimistic forecasts for the future of CDMA technology in China, industry observers stressed that internal party politics continue to play a role. The telecommunications situation is even more politicized in Asia than it is here [in the United States] and in Europe,” said industry analyst Herschel Shostek, based in Wheaton, Md. The China Unicom-Qualcomm partnership has been complicated by Chinese demands for greater access to Qualcomm's intellectual property, Shostek added. I would be very skeptical of claims that the political situation [between state-run Unicom and Qualcomm] is resolved.”

Several months ago, Unicom asked the CDG to help develop a subscriber identification module function for CDMA handsets. The group quickly developed one, and Unicom said it will include the feature when its network is launched next year.
