The DailyTech have sourced more details on ATI's upcoming RV550 based graphics cards, mainly in light of more advanced Blu-Ray and HD-DVD decoding capabilities across this new mainstream lineup, previously limited to higher end X1800/1900 models.
ATI's mainstream solution appears to integrate a Xilleon video processor to a Radeon graphics processor. The ATI Universal Video Decoder will be integrated into the GPU and offer extensive video processing capabilities. Video processing capabilities include the ability to decode 40Mbps Blu-Ray and HD-DVD content using only the GPU. Dual-stream decoding is also supported too allowing the Universal Video Decoder to decode two video streams at the same time for picture-in-picture features.
