HKEPC has the scoop on ATI’s upcoming mainstream HD-DVD and Blu-Ray playback solution. ATI’s AVIVO video processing engine integrated into every X1000 series graphics card supports H.264 and VC-1 hardware accelerated decoding. However, the mainstream X1300 and X1600 series only support hardware accelerated H.264 and VC-1 decoding up to resolutions of 720p. HD-DVD and Blu-Ray disks are typically encoded in 1080p with H.264 or VC-1. Hardware accelerated decoding of 1080p H.264 or VC-1 content is reserved for ATI’s higher end X1800 and X1900 models only.
