Format wars continue as bilingual interpreters appear

Broadcom Corporation recently announced a complete system-on-a-chip (SoC) solution that combines both Blu-ray and HD DVD optical disc formats into a single-chip design.

According the press release, the Broadcom BCM7440 offers OEMs a single 761-ball BGA chip design, which integrates a multiple-core MIPS architecture, a multi-stream HD video decoder, dedicated graphics engines, DSP-based audio processors, a security processor, DDR2 interfaces, integrated video and audio outputs and a complete array of system and network connectivity interfaces.

"Broadcom is simplifying the development of next-generation Blu-ray and HD DVD products with a proven, complete single-chip solution that offers OEMs both a time-to-market advantage and cost-effective design," said Peter Besen, Vice President, Consumer Electronics, Broadband Communications Group, of Broadcom.

"Consumers have expressed interest in adding high definition disc players to their home theater and personal movie entertainment systems, but are cautious about adopting the 'wrong' format," said Richard Doherty, Research Director of The Envisioneering Group. "We have found that four out of five American consumers have expressed knowledge of and/or interest in the availability of consumer products and PCs which could play both HD DVD and Blu-ray media. Broadcom's complete Blu-ray/HD DVD solution is best positioned to drive the wide adoption of the kinds of high-performance, dual-format products consumers want."

The BCM7440 incorporates the decoding, processing and memory functions for both Blu-ray and HD DVD media players, eliminating the need for manufacturers to build two different hardware platforms. The chip supports the wide variety of mandatory audio and video compression standards required for Blu-ray and HD DVD optical disc formats, including H.264/AVC, VC-1 , MPEG-2, Dolby Digital Plus, Dolby Tru-HD and DTS-HD. The BCM7440 also provides full backwards compatibility for current DVD video titles as well as DVD-R, DVD-VR and audio CDs.

The BCM7440 is now sampling in volume quantities to early access customers. No hybrid players using the new chip have been announced yet.

Last month, NEC announced a similar development of a dual-format chip. The next step in bridging the two formats could be a hybrid optical pick-up that would be capable of reading media from both formats.





"Paying an extra $500 for a computer in this environment -- same piece of hardware -- paying $500 more to get a logo on it? I think that's a more challenging proposition for the average person than it used to be." -- Steve Ballmer
