流媒体在广电网络中的架构与实现

Structure and realization of streaming media technology in radio & TV network

流媒体是采用流式传输的方式在Internet中播放的媒体格式,将音频、视频等多媒体文件经过压缩,进行连续的传输。在流式传输的实现方案中,一般采用HTTP/TCP来传输控制信息,而用RTP/UDP来传输实时声音数据。文中介绍了流媒体技术在有线电视网络中建立宽带流媒体平台的结构和主要应用服务。

Streaming media is a media-playing form in Internet via streaming transmission, which can transmit compressed audio, video and other media files continuously. In realization of streaming transmission, HTIP/TCP is generally applied to transmit control information, while RTP/UDP is used in transmitting real-time sound data. The paper puts forward the structure of establishing broadband streaming media platform in cable TV network and offers its main applied services.
