摘要
针对导播系统多路通道播出的应用场景,通过设备状态实时获取、播出视频信号源传输路径分析、导播指令分析、播出视频信号校验等方法,实现多导播系统多路通道播出信息的校验,避免重复视频信号播出。
Aiming at the application scenario of multi-channel broadcasting in multicast system,the verification of multichannel broadcasting information in multicast system is realized by means of real-time acquisition of equipment status,transmission path analysis of broadcasting video signal source,analysis of broadcasting instructions and verification of broadcasting video signal,so as to avoid repetitive video signal broadcasting.
