Rtf provides end - to - end network transport functions suitable for applications transmitting real - time data , such as audio , video or simulation data , over multicast or unicast network services . rtcp monitors the data delivery in a manner scalable to large multicast networks , and to provide minimal control and identification functionality . h . 323 and sip use the real - time transport protocol to transmit real - time data . at the end of this section , we provide the guidelines for writting of rtf payload format specifications 这两个协议的内容是非常重要的，实现原理都是采用组播方式，我们在互连网上传输视频音频将使用这两个协议，而对于更高层次的协议框架h 323 ， sip ，在其底层传输视频音频通常也是采用rtp rtcp协议。 rtp灵活地支持对众多视音频编解码的负载格式，这一部分的最后给出了就如何将视频音频数据进行rtp包封装的一般原则。
