Abstract :
The paper studied mainly the context-based adaptive binary arithmetic coding (CABAC) and its concerned implement strategies in the h.264. The improved CABAC adopted Finite-State-Machine and Lookup-Table to implement its arithmetic coding engine. Compared with the normal CABAC, the improved one is conceptual simple and outputs lower bit-rate with better efficiency. Finally, its test model is evaluated and verified.
