Description: The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for
the coding (compression) of natural video images. The new standard [1] will be known as H.264 and
also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding:
Context-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC).
This document provides a short introduction to CABAC. Familiarity with the concept of Arithmetic
Coding is assumed (see chapter 8 of [2] for an introduction to Arithmetic Coding).-The Joint Video Team (JVT) of ISO / IEC MPEG and the ITU-T JTC 1 are Finalizing a new standard for the coding (compression) of natural video images.

Description: H.264/MPEG-4 AVC is the latest generation standard from the ITU-T and ISO/IEC
MPEG standardization bodies and it builds on the success of the previous ITU-T and
MPEG standards. H.264/MPEG-4 AVC offers major advantages compared with
previous standards, among them its high compression efficiency, although it demands a
high degree of computational complexity to be able to make use of the advantages of its
new techniques. In this paper several implementation issues of the H.264/MPEG-4
AVC standard have been reviewed, dealing with some of the real time challenges that
appear on this kind of implementation. This implementation is to be executed on a
general purpose DSP conforming with the requirements of the broadcast environments
and should provide very important advantages over an MPEG-2 Encoder system.
