说明：  RTP 协议是IETF ( Internet Engineering TaskFo rce) 在RFC1889 中给出的, 是专门为交互式音频、视频、仿真数据等实时媒体应用而设计的轻型传输协议。RTP 被定义为在一对一或一对多的传输情况下工作, 其目的是提供时间信息和实现流同步。RTP 通常使用UDP来传送数据, 但RTP 也可以在TCP 或A TM 等协议下工作.对H.264网络开发有何大帮助！！
( The RTP protocol is given in RFC1889 by IETF (Internet Engineering TaskFo rce), light transmission protocol is designed specifically for interactive audio, video, simulation data and real-time media applications. RTP is defined as working one-on-one or one-to-many transmission, its purpose is to provide time information and stream synchronization. RTP typically use UDP to transfer data, but the RTP in the protocol of the TCP or A TM. H.264 network development of the help! !)
