IPTV终端与平台标准化接口模型研究

IPTV产业近年来在全球发展迅速，是三重播放业务的典型代表。但是终端与平台接口标准的缺乏成为制约IPTV发展的“瓶颈”。实现IPTV标准化的进程需要研究IPTV与广播、通信及互联网3种体制的关系。采用IPTV终端与三网的横向接口横型，可以解决目前在业务整合阶段标准化接口模型架构的问题；采用以横向架构为基础的纵向协议接口模型，可以确定协议接口标准化向全IP演进的方向；以标准协议接口为基础，在IPTV中引入中间件的方式能够有效降低应用开发的门槛。

Research on Standard Interface Model Between IPTV Terminal and Platform

With the rapid growth of the global IPTV industry in recent years, IPTV has become a representative of the Triple-Play services. However, lack of standards for the interface between the terminal and the platform has been the bottleneck of IPTV development. In order to realize IPTV standardization, the relationship between the IPTV system and the broadcast cable network, telecommunication network and Internet should be carefully researched. The horizontal interface model between the IPTV terminal and the three networks is a solution to architecture of the standard interface model at the current phase of service integration. On the basis of the horizontal interface architecture, a vertical protocol interface model is proposed to validate the development trend of IPTV protocol interface standardization towards the all-IP. Based on the standard protocol interfaces, introduction of middleware effectively lowers the threshold of IPTV application development.
