基于TCP/IP的数字实时视频流网络传输的实现

Realization of Digital Simultaneous RTSP Internet Transmit Based on TCP/IP

近几年,视频数字化在教育、国防、公共安全领域都有很多的应用,视频进行数字化处理后可以方便传输和存贮。对于视频的实时传输,当前流行和应用比较多的有两种:实时流式传输协议(RTSP)和MicrosoftMedia服务器(MMS)协议,它们都属于应用层的协议,可以控制音视频的传输。文章探讨的是基于TCP/IP协议簇对压缩后视频的原始码流(ES流)进行处理和传输,不依赖于MMS和RTSP,并对其发送缓冲区进行有效管理,实现视频的连续、实时、有效的控制和传输。

In recent years, video frequency digitalization has been widely used in such domains as education,national defense and public security. After being digitalized video frequency can be transmited and stored conveniently. As far as RTSP transmission of video frequency is concerned, there＇re two kinds which are popular and often used today：the agreement on RTSP and the agreement on the MMS, and both of them belong to agreement on the layer of application, which can control the transmission of video - audio frequency. This article is to explore the realization of RTSP and transmit condensod ES current of video frequency, the whole of process is based on the agreement on TCP/IP, and without the usage of MMS and RTSP, and its transmission buffer division will be managed effectively to realize the successive, simultaneous and effective control and transmission of video frequency.
