Embodiment Construction

[0037] The present invention proposes a radio and television broadcast control system. As shown in FIG. 1, the system includes a first video server 101 and a second video server 102, and the broadcast information is obtained by the first video server 101 through the first decoding channel A. The main broadcast signal is sent to the audio-visual multi-choice device 105 for output, and the second video server 102 outputs the backup broadcast signal to the audio-visual multi-choice device 105 through the standby decoding channel B for backup of the broadcast signal. The system also has a control device 104 and a second switching device 203, the control device 104 controls the second switching device 203 to switch the control right of the standby decoding channel B, and then controls the second video server 102 to output the standby decoding channel B through the standby Broadcast the signal or output the review signal, and then send the signal to the video-audio multi-choice devic...

Abstract

The method comprises: the first video server outputs the main broadcast signals to the audio and video 'choosing one from multiple device through main decoding channel; the second video server outputs the standby broadcast signals to the audio and video 'choosing one from multiple' device through the standby decoding channel; the standby decoding channel of said second video server is taken as a sharing decoding channel, and the control device controls the second switch device to switch the control right of the standby decode channel in order to make the second video server output the standby broadcast signals to the audio and video 'choosing one from multiple' device or outputs the examined signals to the examining end; so as to realize the sharing of the examining decode device and the standby broadcast decode device.

Description

technical field [0001] The invention relates to radio and television broadcast control technology, in particular to a broadcast and television broadcast control method and system. Background technique [0002] In the radio and television system, video servers are widely used. At present, most TV stations basically adopt a mixed broadcast mode that mainly uses video servers, video recorders and external signals. The general working mode of broadcasting is: [0003] 1. Store most of the materials in the video server in various forms. [0004] 2. After the material is ready, check the material through a decoding channel of the video server, confirm that there is no problem, pass the review, and copy the material to another video server. [0005] 3. Most of the content to be broadcast is based on the materials in the video server, and the main and backup two decoding channels are used to output information and broadcast. The main signal of the video server is used as the final ...
