基于信息隐藏的视频重同步算法

A Video Resynchronization Algorithm Based on Information Hiding

针对数字视频通信系统提出一种新型的重同步控制算法。利用信息隐藏技术传递压缩视频码流中的重同步信息,可根据实际信息嵌入量实现变精度的误码重同步,降低各种随机信道误码对视频解码的不良影响,为受损图像的逼真重建提供有利条件。

A new video resynchronization control algorithm in video communication is proposed.Some information about synchronization are transmitted by the information hiding techniques, according to the actual embedding capacity, decoder can be re_synchronized with the variable precision in a slice. It can reduce the influence caused by some kinds of random bit errors in the decoding process, and provide the favorable conditions for the error concealment.
