    Abstract:

    The context-based adaptive binary arithmetic coder (CABAC) is the preferred entropy encoding method in the main profile of H.264/AVC, for it can offer more bit rate saving than other entropy coding methods. However, high computational complexity and poor parallelism make it unsuitable for chip multicore processors application. A new CABAC parallel encoding method is proposed for the troubleshooting. Results from experiments show that the proposed method can indeed strike a near balanced workload partition while achieving a peak speedup of 1.78 when solely applied.
