针对视频传输时容易发生损坏或丢失的特点，为了更好地恢复图像质量，提出了基于H.264/AVC 平台的自适应时域错误隐藏方法，该方法依据边界失真准则自适应转换两种隐藏方法，一种是初次隐藏，另一种是集成隐藏。集成隐藏采用自适应加权集成初次隐藏和增强隐藏。实验仿真结果表明方法改善了隐藏性能。

To recover the quality of image better for the characteristics of error-prone or loss-prone in video transmission, temporal error concealment which is self-adaptive based on H.264/Avc is proposed in this paper. The method based on boundary distortion switches two methods by itself. One is primary concealment mode and the other is integrated concealment mode. The integrated mechanism which adopts self-adaptive method integrates primary concealment mode and enanced concealment. Experimental results show that the technique could effectively enhance the performance of error concealment.
