摘要： 在H.263的“混合编码”法,即帧间预测与帧内变换相结合的编码方式的基础上,引入了帧内预测的编码方法,并对H.263视频编码结构进行了改进。从理论上对帧内变换+预测编码方法与H.263中单一的帧内变换编码的比较,得出其优点,实现了引入帧内预测的H.263的软件编码器,并通过实验验证了帧内变换+帧内预测+帧间预测的混合编码方法的优越性。

Abstract: Based on hybrid video coding method in H.263, namely intra transform combined with inter prediction coding method, This paper introduces intra prediction coding method and improves the coding structure of H.263. This paper compares two different methods in theory, educes the advantage of latter method, realizes H.263 software coder with intra prediction, and validates the superiority of such coding method by experiment.
