Automatic broadcast four-stage automatic switching device and method

Abstract

The invention relates to an automatic broadcast four-stage automatic switching device and an automatic broadcast four-stage automatic switching method. The device comprises a master broadcast control workstation, a standby broadcast control workstation, a master video server, a standby video server, a following camera and switching equipment, wherein a converter is arranged between the master andstandby broadcast control workstations and broadcast equipment, such as the master video server, the standby video server and the like, and controls the conversion of control links of the master and standby broadcast control workstations through GPI signals of the standby broadcast control workstation by means of an RS422 interface circuit; and the switching equipment is controlled by the broadcast control workstations. The automatic broadcast four-stage automatic switching device realizes the four-stage automatic switching of broadcast signals according to the order of the master and standbyvideo servers, the following camera and an emergency signal source, changes a conventional operation mode that broadcasters perform manual emergency switching according to the signal output conditionof the switching equipment, greatly reduces the working strength and mental stress of the broadcasters in television stations, realizes the automatic detection and quick processing of faults, effectively avoids the occurrence of broadcast accidents and comprehensively improves the security and reliability of a broadcast system.

Description

technical field [0001] The invention relates to an automatic broadcasting four-stage automatic switching device and method, which is a method for automatic emergency operation inside a broadcasting system under a computer network environment, and a four-stage automatic switching technology for broadcasting channels of a video server. Background technique [0002] Usually, broadcasting security is an extremely important consideration when TV stations or other broadcasting organizations of video and audio programs design and build broadcasting systems. Broadcast security is mainly reflected in whether the broadcast system adopts a reasonable redundant backup structure, and has high security and configurable automatic emergency switching technology. At present, the emergency switching technology adopted by the broadcasting system of the TV station is in a relatively primitive state, which cannot guarantee the high security and high reliability of the broadcasting system.

AI Technical Summary

Problems solved by technology

For example, when the anchor control workstation breaks down, the set of broadcast equipment it controls cannot broadcast normally.

At this time, the staff needs to control the 2-to-1 switch for manual switching in the shortest time, and manually switch the final broadcast signal to the output of the standby switching matrix controlled by the standby broadcast control workstation. If the staff is slightly negligent, it will lead to broadcast Broadcast accidents such as black frames and static frames appear on the screen
