再次压缩 meaning in English

recompression

The algorithm study is in detail that one channel of video - stream is recompressed by mpeg - 2 standard so that its bit - rate will be changed lower . then , multi - date streams will be processed by the technology of statistical remultiplex . the dynamic signals of every single data - stream " output can drive the values of bit - rate of the corresponding single data - stream
本次算法研究具体地说就是按照mpeg - 2的标准对单路mpeg - 2视频流再次压缩，将其码率变的更低，并且提出对多路码流进行统计复用，根据单路码流的输出动态信息对码流进行动态的调整的框架。
