Description: H.264/AVC is newest video coding standard of the
ITU-T Video Coding Experts Group and the ISO/IEC Moving
Picture Experts Group. The main goals of the H.264/AVC standardization
effort have been enhanced compression performance
and provision of a “network-friendly” video representation
addressing “conversational” (video telephony) and “nonconversational”
(storage, broadcast, or streaming) applications.
H.264/AVC has achieved a significant improvement in rate-distortion
efficiency relative to existing standards. This article provides
an overview of the technical features of H.264/AVC, describes
profiles and applications for the standard, and outlines the history
of the standardization process.
