摘　　要：根据DVB-S2码流自身的特点以及参考二维视频数据的传输,提供了三维视频节目在第2代卫星广播电视标准信道中的3种基于数据链路层传输方式,并给出了相应的发送协议栈.根据每种传输方式的规定,计算了每种情况下码流的传输效率,并进行对比.综合各种因素,得出每种传输方式都有自己的优缺点和适用范围,任何一方都不能完全被替代.According to the characteristics of DVB-S2 streams and 2D data transmission, three kinds of transmission modes based on the data link layer are provided in the DVB-S2 channel, and the corresponding transmission protocol stacks are also given. According to the regulation of transmission modes, the transmission efficiency is calculated in each case and then a comparison is made. Synthesizing various factors, we conclude that each transmission mode has its own advantages and disadvantages in different applications, and that none of them cannot be completely replaced by others.
