摘　　要：无线视频移动信道是高误码率,具有突发错误的信道。高效压缩的视频信号对传输过程中的错误非常敏感,容易造成宏块连续出错,不利于错误隐藏的有效实施。本文提出一种基于宏块的交错扫描方法,使得相邻宏块不同时发生错误。分析和实验表明,这一方法对出错视频图像的恢复具有明显的有效性。Wireless channels for mobile video communication usually have high error bit rate and burst errors. High compressed video is sensitive to transport errors, and it will lead to continuous errors in microblocks, which is not convenient for error concealment. In this paper, a new way to arrange macroblocks with interleaving is presented, and it makes the adjoining microblocks not have errors at the same time. The analysis and simulation show that this technique is obviously efficient in video error-recovery.
