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 a control command is sent to the signal output equipment of the secondary event by the signal output program of the primary event; the secondary event signal is output by the signal output equipment of the secondary event; the output secondary event signal and the primary event signal are composited to a signal for broadcasting. The invention discloses a secondary event broadcasting system of broadcasting television system. The invention has the advantages of controlling a plurality of repeated actions in compliance with certain rules of the signal output equipment of the secondary event through a command, sending the related information required by the signal output of the secondary event to the signal output equipment of the secondary event by the signal output program of the primary event according to the practical situation of the broadcasting of primary event, reducing the burden of the signal output program of the primary event, and lowering the error ratio.

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. Background technique [0002] Usually, when a TV station broadcasts video and audio programs, it is necessary to insert some auxiliary signals as a necessary supplement, and broadcast them together with the video and audio signals. Among them, auxiliary signals mainly include the following types: station logo, which is used as a channel logo; clock, which reminds time at a specific moment; corner logo, which can be used as a supplement to the station logo, and can also be used to display signals such as TV series names; subtitles, Different from the subtitles of the program itself, it can be used to display the latest news events, weather forecasts, advertisements, etc.; the countdown timer can be used as a reminder before the program starts; the picture advertisement after the T...

Problems solved by technology

[0005] However, as TV stations have higher requirements for the broadcasting of secondary events, more and more complex broadcasting requirements make the triggering of the secondary event signal output device more and more frequent by the primary event signal output program, for example: it is required to Start broadcasting the footnote of the advertisement, stop playing after 0.5 minutes, stop playing for 1.5 minutes, and then play for 0.5 minutes, ..., and so on. The first-level event signal output program needs to trigger 46 times on the second-level event signal output device, and the frequent triggering of the second-level event signal output device by the first-level event signal output program not only increases the burden of the first-level event signal output program, but also causes Increased error rate during playout

[0006] In addition, due to some relevant information required in the output of the secondary event signal, such as the advertisement countdown time, the name of the current program, the content of the program preview, etc., at present, the relevant information required for the output of the secondary event signal is based on the broadcasting of the primary event The order is pre-set in the secondary event signal output device, so when the primary event is adjusted, if the information in the secondary event signal output device cannot be modified in time, it is easy to appear that the broadcasted secondary event is different from the primary event. event mismatch error
