有线电视系统多重MPEG-2传送流的时分复用及传送流的一般格式 |
ITU-T J.183建议书介绍在有线电视系统上,通过简单实施MPEG-2系统的物理界面,进行多个MPEG-2传送流和/或传送流通用格式传输的时分多路复用(TDM)格式。TDM帧将MPEG-2传送流和/或传送流通用格式进行封包,后者在传送前,被分成188个字节长的数据包。该建议书还说明通过信道绑定技术实现的高速度帧结构。 该格式的特点是与现有卫星跨调制格式具有互操作性,后者以附件C/J.83和附件C/J.84(SMATV系统C(III))的规范为基础。 该建议书可能也适用于其它传输系统。如果将该格式引入现有数字有线电视系统中,则建议将帧格式信息与网络信息表同时进行传送。还需要机顶盒确定包含多个MPEG-2传送流和/或传送流通用格式的数字信道。 |
