  ASTRI H.264 High Profile Video Decoder
   
 

Overview
H.264 Advanced Video Coding (AVC) is the latest and most advanced video coding standard recommended by ITU & ISO. It contains a rich set of video coding tools to support a variety of applications ranging from video conferencing, digital broadcast, to digital storage media. Subsets of coding tools are defined as profiles. The most widely used profiles are Baseline Profile (BP), Main Profile (MP) and High Profile (HP). High Profile has the most complexity, supports HDTV, HD-DVD and Blue-ray High-Definition DVD applications.
