Design and Implementation of Multi-Channel Digital Television Program Processing System Based on Distributed Transcoding
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.
