Embodiment Construction

[0038] The signal switcher is one of the components of the N+1 TV transmission system. It mainly realizes the switching and selection functions of multiple audio, video, or TS transport streams. It can be used to realize the selective output among multiple analog audio, video and digital TS streams, and supply the modulation and transmission equipment of the later stage.

[0039] The remote control signal uses the network port data, and the local switch adopts the manual button (toggle switch); the priority of the local switch is higher than that of the remote switch.

[0040] The signal switcher uses two 8-channel multiplexer switch controllers. 12 (6X2) signals can be input at the same time, two channels are a group. You can choose to output any one of the 6 groups of signals.

[0041] Cooperate with the network control chip for remote signal switching management. Implement real-time status monitoring.

[0042] At the same time, with the 6-way interlock button, the remo...

Abstract

The invention relates to an N+1 television emission system, which is a multichannel digital television emission system with high reliability and quick response. When a main transmitter of the emission system breaks down and cannot broadcast normally, the emission system makes the quick response, and the main transmitter is replaced by a backup transmitter until the main transmitter is repaired and switched to maintain the normal operation of the system. The N+1 television emission system improves the power efficiency of the transmitter greatly, saves energy, reduces the emission of heat on space, and has positive significance for environmental protection and energy conservation; and simultaneously, the N+1 television emission system improves the operating quality of the television transmitter, improves the level of the television transmitter in China and shortens the difference between China and developed countries. The N+1 television emission system is characterized in that: the backup transmitter is cold backup instead of hot backup; the single transmitter has the advantages of high power efficiency, energy conservation and environmental protection; and the system can realize remote control management and large-capacity record, and is switched automatically to realize unmanned guard.

Description

technical field [0001] The quick-response N+1 television transmitting system involved in the present invention is a multi-channel digital television transmitting system with high reliability and quick response developed in order to improve the reliability of the digital television transmitting system. When a main transmitter of the transmitting system fails and cannot be broadcast normally, it can make a quick response and replace the work by the backup transmitter, and then switch back until the main transmitter is repaired; ensure the normal operation of the transmitting system. At the same time, it realizes the functions of intelligent fault handling, remote telemetry and remote control, and data management for the transmitter. This project is very important for improving the reliability of digital TV transmission; and because of the present invention, the power efficiency of the transmitter itself is greatly improved, not only energy is saved, but also heat emission to spa...
