ARC Introduces Configurable Video Subsystems By BDTI, 8/22/2007 Adding to its growing portfolio of licensable silicon IP subsystems, ARC has announced five configurable video processing subsystems. The subsystems range from the smallest-size AV 402V to the highest-performance AV 417V, and support multi-standard video encoding and decoding at resolutions ranging from CIF to D1. (More)

How Video Compression Works By Jeff Bier, 8/15/2007 Digital video compression/decompression algorithms (codecs) are at the heart of many modern video products, from DVD players to multimedia jukeboxes to video-capable cell phones. In this article, we explain the operation and characteristics of video codecs and the demands codecs make on processors. (More)

Tensilica Offers High-Performance Licensable Video Engine By BDTI, 7/18/2007 Tensilica has announced 388VDO, a high-performance “Diamond Standard” core. The 388VDO offers the highest performance among Tensilica’s four new dual-core video engines, which support multiple video standards including H.264 and MPEG-4. The 388VDO is also the only VDO core that supports MPEG-4 ASP encoding. (More)

Jeff Bier's Impulse Response—Signal Processing Algorithms Easier to Create, Harder to Sell By Jeff Bier, 7/18/2007 One of the things I really love about digital signal processing technology is how, year by year, it gets easier to create new things. Things like clever new audio or video compression algorithms, for example. (More)
