The pdfs to which these codes correspond are well matched to statistics of image and video data, thus enabling an increase in robustness to channel errors with no penalty in coding efficiency.
其编码数据格式能够很好地应用于图像和视频的统计编码中，在保持编码效率的同时，很大程度地提高编码在信道传输中的纠错能力。
However, the compressed video data is highly sensitivity to error code. A few error codes may induce much code be decoded invalidly.
而且压缩后的视频数据对码元错误非常敏感，少量码元的错误就可能导致大批码元无法正确解码。
The coding module compresses and codes the video data under the control of the output signal of the key frame discriminant module and the important regional identification module.
在关键帧判别模块和重要区域识别模块的输出信号控制 下，编码模块对视频数据进行压缩编码。
