The new 720MHz version of the TMS320DM642 DSP-based digital media processor from Texas Instruments Inc. (TI) promises to give manufacturers of consumer electronics and STBs a clear path to delivering high definition (HD) streaming video.

The digital media processor delivers HD video streams in Microsoft's Windows Media High Definition Video (WMV HD) format at 720p resolution, as well as MPEG-4, MPEG-2 and MPEG-1 formats. It also processes standard definition video decoding for the emerging H.264 format.

In addition to sampling the 720MHz version of the DM642, the company is now offering production class devices for the TMS320DM640 and TMS320DM641, plus the 600MHz version of the DM642. These code-compatible digital media processors are scalable across a wide range of clock speeds and memory capacities to support applications from video-based consumer electronics to video infrastructure equipment.

The DM642 includes integrated multimedia and communications peripherals such as on-chip HD-capable video ports, glueless Ethernet connectivity, multi-channel audio and 66MHz PCI connectivity. TI said the 720MHz version offers higher performance for HD streaming and broadcast applications, as well as headroom for extended features such as object recognition and tracking for surveillance applications, multiple channel decode for streaming applications and image cleanup, network transport, better audio quality and better system control for other video applications. Additionally, the DM641 and DM640 processors also support video ports and critical peripherals for digital media adapters, personal video recorders, consumer IP-based video phones and video conferencing systems and digital surveillance systems.

The DM640, DM641 and DM642 (600MHz version) are already available in volume production, with pricing starting at $19.95 each in quantities of 10,000 for the 400MHz DM640. The TMS320DM642 running at 720MHz is sampling today at $59.99 (10,000-unit orders). The DM642 Evaluation Module (EVM) is priced at $1,995, while the DM64x-based Digital Media Developer's Kit (DMDK) is available for $6,495 (includes the DM642 EVM).
