数字电视多媒体消息系统的接口协议

Research on Interface Protocol Research of Digital Television's Multimedia Message System

论述了数字电视多媒体消息系统(TVMMS)的网络结构设计,主要研究了数字电视多媒体消息系统中MM1接口协议及其实现方法,使之可以实现机顶盒与机顶盒之间点对点的消息互通、机顶盒与增值业务提供商之间的消息互通、机顶盒与手机等其他网络终端之间的消息互通,并用SIP协议对用户代理进行了简单的设计.

This paper discusses the lattice structure design of digital TV Multimedia Message System （TVMMS）, studies its MM1 interface protocol and realizing method so as to realize point to point commu- nication between STBs （set top box）, communication between STB and VASP （Value Added Services Provider）, communication between STB and mobile phone, communication between STB and TV stations. And user agent is simply designed by using SIP protocol.
