摘要

本文提出了一种抗错误编码结构。首先提出了一种扩展的双帧运动补偿(DFMC)编码结构，然后在Macroblock (MB)级速率失真代价决策中采用带错误弹性滤波器的端到端失真模型进行模式决策，最后在帧级速率代价决策中确定HQF中的报头比特数。实验结果表明，该方法比以往的方法具有更好的性能。

Error Protection with Extended Dual Frame Motion Compensation

In this paper, an error resilient coding structure is proposed. Firstly an extended dual frame motion compensation (DFMC) coding structure is proposed, and then an end-to-end distortion model with error resilient filter is used for mode decision in Macroblock (MB) level rate distortion cost decision, finally the number of header bits packet in HQF is determined in frame level rate cost decision. Experimental results show that the proposed method can achieve better performance than previous schemes.
