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.
ASTRI H.264 High Profile Video Decoder is a high performance
application specific silicon IP core, which compliant with
ITU-T Recommendation H.264 | ISO/IEC 14496-10, and support
H.264/AVC High Profile video stream at resolution up to
1920x1080p@60fps. |
