无差错传输 meaning in Chinese

error free transmission
errorless transmission

Arq ( auto repeat on request ) is used in data communication to garauntee error - free transmission , but it is not suitable for video communication because video communication has stringent delay requirement and limitless retransmission is not allowed
传统的数据通信通过出错重传的方法保证数据的无差错传输，但是这种方法不适合实时视频通信。因为视频通信对延迟有严格的要求，不可能使用无限制的重传。
However , video communication can tolerate some kind of data error or loss and different parts of video bitstream have unequal error sensitivities . so we need new error control methods designed especially for video communicaton
同时视频数据能够容忍一定的误码和丢失，并不需要绝对的无差错传输，而且视频数据流的不同部分对错误的敏感度也不同，因此有必要也有可能根据视频通信的特点研究新的差错控制方法。
