摘　　要：电视播出主要是节目的播出,其次是线路信号的播出。线路信号的播出方式和操作流程与节目播出完全不同。线路信号的播出分为转播和直播,转播的是外来信号,直播信号则来自于本台的演播厅、直播间和直播现场等地。线路信号进入电视播出系统后,要与播出服务器信号和其他信号一道接入播出矩阵,在播出系统控制下完成播出任务。所以进入播出系统的线路信号必须与其他信号统一格式,另外为保障播出安全,在播出前必须解决线路信号的监测和调度问题。TV broadcasting is mainly the broadcasting of programs,followed by the broadcasting of line signals.The broadcast method and operation process of the line signal are completely different from the program broadcast.The broadcast of the line signal is divided into rebroadcast and live broadcast.The rebroadcast is external signals,while the live broadcast signals come from the studio,live room,and live broadcast site of the station.After the line signal enters the TV broadcast system,it must be connected to the broadcast matrix together with the broadcast server signal and other signals to complete the broadcast task under the control of the broadcast system.Therefore,the line signal entering the broadcast system must be in a unified format with other signals.In addition,to ensure the safety of the broadcast,the monitoring and scheduling of the line signal must be solved before the broadcast.
