摘要
在数字视频的网络传输中,若采用单线程方式,取流和传输、接收和解码都不能同时进行,从而造成了CPU的并行效率低下,并容易因网路阻塞而导致系统死锁,使视频传输效率大大下降,必须采用多线程技术实现。
To transfer digital video on Internet, if we use a single thread, reading and packaging, receiving and decoding cannot carry out at the same time. That makes the parallel efficiency of CPU very low, and easy to result in system＇s deadlock by blocks of network. The efficiency of video transferring will fall sharply. Therefore, we have to use multithread technique to realize video transmission.
