Abstract

The invention discloses a terrestrial digital television broadcasting redundancy transmitting device and a redundancy method, and relates to the digital television broadcasting technology. The terrestrial digital television broadcasting redundancy transmitting device and the redundancy method are economical and efficient. The terrestrial digital television broadcasting redundancy transmitting device is characterized by comprising a system controller, a transmitter unit, a selector switch set, a multiplexer and a transmitting antenna. The transmitter unit comprises working transmitters and standby transmitters. The system controller is in signal connection with each selector switch in the selector switch set and each transmitter in the transmitter unit respectively. The system controller is used for switching input programme signals and outputting the programme signals to the working transmitters. The system controller is used for dispatching and controlling each transmitter in the transmitter unit to work or stand by according to the working conditions of the working transmitters and for controlling the selector switch set to connect the radio-frequency signal output ends of the working transmitters to the multiplexer in a coupling mode. The multiplexer is connected with the transmitting antenna in a coupling mode.

Description

technical field [0001] The invention relates to digital television broadcasting technology, and relates to a redundant backup transmitting device and a redundant method for terrestrial digital television broadcasting, which are suitable for network planning and configuration of large and medium-sized television transmitting stations. Background technique [0002] The development of communication and information technology has triggered a huge change in broadcasting and TV. Digital TV will be the center of this change. With the acceleration of conversion from analog TV to digital TV, traditional technology and equipment can no longer meet the needs of the market and users . [0003] In the era of analog TV broadcasting, traditional TV transmission methods usually use figure 1 The shown (master + backup) working mode, that is, if there is a master, a backup must be configured, and automatic switching between the master and backup can be realized. When the master fails, it wil...
