  1. The first facet is to put forward four - step block matching algorithm which can deduce the time of motion estimation and improve the coding efficiency, based on the traditional motion estimation algorithms. the second facet is to propose a new rate control algorithm, that is average - reaction rate control algorithm, based on the rate control of mpeg2. the new rate control algorithm can achieve rapid and efficient adaptive coding

    首先在對傳統的運動估計演算法進行研究和改進的基礎上,提出了四步搜索塊匹配的運動估計演算法,減少了運動估計的時間,提高了編碼效率;其次在分析mpeg2比特率控制的基礎上,提出了一種新的比特率控制演算法? ?平均響應比特率控制演算法,該演算法能夠快速有效的實現自適應編碼。
