Broadcast control method, device and system for broadcast television

Abstract

The invention provides a broadcast control system for broadcast television. The system comprises at least one broadcast control workstation, a control server and at least one piece of controlled equipment, wherein the broadcast control workstation sends a command to the controlled equipment through the control server, and receives the state information of the controlled equipment and the state information of a program series list from the control server; the control server is used for controlling corresponding controlled equipment according to the command of the broadcast control workstation, obtaining the state information of the controlled equipment from the controlled equipment, and broadcasting the state of the controlled equipment and the state information of the program series list to the broadcast control workstation; and the controlled equipment is used for broadcasting according to the control of the control server, and sending the self state information to the control server. The invention also provides a control server and a broadcast control method for broadcast television. According to the invention, the resource utilization rate of the broadcast equipment can be improved, and the security of the broadcast control system is enhanced.

Description

technical field [0001] The present invention relates to a radio and television broadcast control technology, in particular to a radio and television broadcast control method, device and system. Background technique [0002] The working principle of the existing radio and television broadcast control system (abbreviation: radio and television broadcast control system) is: organize various materials into programs, list the programs to be broadcast in the program series list, and the broadcast control workstation analyzes the programs Concatenate orders, and send a broadcast control instruction to the broadcast device, and the broadcast device (such as a video server, video recorder, etc.) broadcasts the program to be broadcast. figure 1 It is a brief schematic diagram of the existing radio and television broadcast control system. [0003] In broadcast television systems, video servers are widely used. At present, the broadcasting equipment of most TV stations basically adopt...

AI Technical Summary

Problems solved by technology

[0017] In the full active / standby mode, since the active and standby video servers are controlled by the main broadcast control workstation, if the main broadcast control workstation crashes at the moment of issuing the Play (play) command, the standby broadcast control workstation at this time is simply not enough. time response and take over the control of the video server, resulting in static frames on both the active and standby video servers at the same time. Emergency Playout on Shim Channel

Moreover, in this way, the active and standby video servers only respond to the main playout control workstation, and the data maintained on the standby playout control workstation and the main playout control workstation are inconsistent

[0018] It can be seen that the existing technology cannot guarantee the security of the broadcast control system
