摘要
以湖北省地面数字电视省级播控平台多画面模块为对象,介绍基于分布式转码技术处理多路地面数字电视节目的解决方案.方案采用纯软件方法将多节目流分解成单节目流,再对单节目流进行推流、转码、转封装,最终实现在一个页面中播放一个地面数字发射台发射的所有电视节目.该方案具有高灵活性和低硬件成本的特点.
Abstract
In this paper,the multiviewer module of the provincial broadcast control platform of terrestrial digital television in Hubei province is taken as the object,and the solution for processing multi-channel terrestrial digital television programs based on distributed transcoding technology is introduced. The scheme adopts a pure software method to decompose multiple program streams into single program streams,and then pushes,transcoding,and remuxing a single program stream,and finally realizes the playback of all TV programs emitted by a number of transmitters on one page,which has the characteristics of high flexibility and low hardware cost.
