摘要: | In this paper, a hybrid model based on hierarchical B picture structure is proposed to improve error concealment effects when there is a whole-frame loss. The model combines two hierarchical B-picture coding structures such that key-frames, reference B frames, or even non-reference B frames have buddy frames to serve as their data recovery frames when they are lost. With buddy frames, the distance between a lost frame and its recovering frame can be substantially reduced and thus error concealment performance can be improved with little bit-rate redundancy. |
