The method includes steps: digital watermark technique is adopted to hide information of key data in not key data codes of compressed image; under protection of digital watermark, using protective backup for key data detects whether normal transmitted key data is correct or not so as to detect error code; carrying out cyclic mutual backup by using macro blocks in same positions in front and back macro block set; embedding coded motion vector in form of digital watermark to DCT transformation coefficient, and ensuring that video data are not influenced as best as one can; when error code occurs, if key data backup is correct, then the backup replaces former key data; otherwise, using mean value of key data in adjacent macro blocks within same frame to replace former key data approximately.

本发明中，采用数字水印技术在压缩图像的非关键数据编码中隐藏关键数据信息；通过数字水印保护下的关键数据保护备份来检测正常传输的关键数据是否正确，由此来检测传输误码；用前后宏块组中相同位置的宏块进行循环相互备份；对运动向量进行编码，然后以数字水印的形式嵌入到相对不重要的DCT变换系数中，同时保证视频数据尽量不受影响；在误码发生时，如果关键数据备份正确，则直接替代原关键数据，否则用同一帧内相邻宏块的关键数据的平均值近似替代原关键数据。
