随着广播电视编解码和传输设备IP化接口的广泛出现,基于TS over IP的信号传输体系架构越来越得到广泛关注。本文主要介绍了中央电视台基于TS over IP的播出信号编码压缩系统架构,并面向新媒体、传统地面站等不同类型的下游接收用户,分析阐述了IP节目流的传输分发方式。
With the widespread appearance of IP-based interfaces for encoding and decoding of broadcasting and TV equipment, the signal transmission architecture based on TS over IP has drawn more and more attention. This paper mainly introduces the architecture of CCTV broadcast signal coding and compression system based on TS over IP. It also aims at different types of downstream users such as new media and traditional terrestrial stations, and analyzes and expounds the transmission and distribution of IP program streams.
