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
