介绍了基于MPEG-2视频码流隐错的基本步骤以及码流的基本框架结构,在分析人眼特性的基础上提出了隐错应充分利用人眼的噪声掩盖特性以保证算法的实时性。最后,提出了一种基于视觉效果的隐错算法。
The basic steps of MPEG-2 video code stream error concealment and the basic frame structure of the code stream are introduced. Based on the analysis of the human eye characteristics, it is proposed that the error concealment should be fully utilized to ensure the real-time performance of the algorithm. Finally, a visual error-based algorithm is proposed.
