H.264/AVC, the result of the collaboration between the ISO/IEC

Moving Picture Experts Group and the ITU-T Video Coding

Experts Group, is the latest standard for video coding. The goals

of this standardization effort were enhanced compression efficiency,

network friendly video representation for interactive

(video telephony) and non-interactive applications (broadcast,

streaming, storage, video on demand). H.264/AVC provides

gains in compression efficiency of up to 50％ over a wide range

of bit rates and video resolutions compared to previous standards.

Compared to previous standards, the decoder complexity

is about four times that of MPEG-2 and two times that of

MPEG-4 Visual Simple Profile. This paper provides an overview

of the new tools, features and complexity of H.264/AVC.-H.264/AVC, the result of the collaboration between the ISO/IECMoving Picture Experts Group and the ITU-T Video CodingExperts Group, is the latest standard for video coding.
