Secondary event broadcasting method and system in broadcast television system

Abstract

The invention discloses a secondary event broadcasting method of broadcasting television system, which comprises the steps that the secondary event broadcasting schedule is edited by the signal output equipment of the secondary event; the signal output equipment of the secondary event adjusts the secondary event broadcasting schedule according to the changed primary event broadcasting program sheet as the primary event broadcasting program sheet changes; the secondary event signal and the primary event signal are composited to a signal for broadcasting as the television program is broadcast. The invention discloses a secondary event broadcasting system of broadcasting television system. The invention has the advantages of lowering the workload of operators because the changed primary event broadcasting program sheet is passed to the signal output equipment of the secondary event in order to adjust the secondary event broadcasting schedule as the primary event broadcasting program sheet changes, preventing the error that the primary event is not matched with the secondary event partially, and realizing the synchronous jump of the signal output equipment of the secondary event as emergency occurs.

Description

technical field [0001] The invention relates to radio and television broadcasting technology, in particular to a method and system for broadcasting secondary events in a radio and television system.

Problems solved by technology

That is to say, in the prior art, the first-level event signal output device outputs the first-level event signal according to the first-level event broadcast program list, and the second-level event signal output device outputs the second-level event signal according to the second-level event broadcast plan. There is no interaction between them. When the broadcast program list of the first-level event changes, and the clock of the first-level event signal output device is inconsistent with that of the second-level event signal output device, it is necessary to manually modify the correspondence according to the change of the first-level event broadcast program list. The second-level event broadca
