Abstract

Techniques for addressing syntax element information of neighboring macroblocks for processing a current macroblock based on H.264 Content Based Adaptive Binary Arithmetic Coding (CABAC) are disclosed. The techniques can be used for one line of macroblocks for Frame or Field only mode, and two lines of macroblocks for MBAFF mode. The techniques can be implemented, for example, using gate-level logic state machines as part of a system-on-chip (SOC) solution for a video/audio decoder for use in high definition television broadcasting (HDTV) applications.
