Problems solved by technology

[0006] In the case of simultaneous live broadcast on multiple broadcast channels, the start and end time of the live event or scene concerned by each broadcast channel is different, that is, during the live broadcast, some broadcast channels have no available video for a period of time The signal needs to be displayed according to the record of the director to display the video content displayed on other broadcast channels. Generally, videos from other shooting angles different from it are selected as auxiliary display methods for the same scene. However, in actual operation, due to the fact that the two broadcast channels display Overlap occurs, and with the continuous switching of different camera bit images by the broadcasting director unit, it is easy to cause multiple broadcasting channels to broadcast repeated video signals at a certain moment;
[0007] When accidents occur in the live broadcast task and cannot be executed strictly according to the director’s script, such as signal disconnection, event delays, emergencies, etc., multiple broadcast directors are prone to poor communication in a short period of time, resulting in repeated broadcasting of multiple broadcast channels the condition of the video signal;
[0008] The operator of the broadcast guidance system caused repeated video signals to be broadcast on multiple broadcast channels due to misoperation
[0009] Therefore, there is a certain probability of repeated video signal broadcasting when the broadcasting system broadcasts multi-channel images, and the broadcasting system often further improves and refines the broadcasting program, filing, and timely communication and careful operation of the broadcasting system operators to avoid This problem occurs, but there is no good solution for handling misoperations and emergencies

Abstract

The embodiment of the invention provides a video playing method and apparatus, and belongs to the technical field of broadcast guidance. The method comprises the following steps: obtaining a broadcastguidance instruction, wherein the broadcast guidance instruction is used for indicating that a current video signal is output from a first output channel to a first display device at a current time;determining whether the current video signal has been output from a second output channel to a second display device prior to the current time based on the broadcast guidance instruction; and when itis judged that the current video signal has been output from the second output channel to the second display device prior to the current time, stopping outputting the current video signal from the first output channel to the first display device. Therefore, the problem of a live broadcast accident caused by the repeated playing of the same video signal is avoided, and the flexibility, integrity, tightness of real-time monitoring of played information of a broadcast guidance control system, and the live broadcast efficiency are improved.

Description

technical field [0001] The present invention relates to the technical field of broadcasting, and in particular, to a video broadcasting method and device. Background technique [0002] With the rapid development of radio and television technology, the gradual improvement of information and communication methods, and the popularization of monitoring and portable camera equipment, the information sources of live broadcast tasks have been greatly enriched. However, live TV broadcasting adopts the original method of one-screen live broadcast, which makes it difficult to comprehensively display various important events of the live broadcast scene. After the massive live video information is selected by the broadcasting system, it often loses sight of the other, and many important and wonderful multi-angle live videos are lost. content, it is difficult to meet the audience's personalized, diverse and comprehensive perspective needs. In live broadcast tasks, multiple cameras are g...
