Embodiment Construction

[0013] Now take a concentrated viewing of a set of CCTV live broadcast activities as an example to explain the system solution. The main signal uses the existing HFC network. The signal in the central computer room is transmitted to the optical receiver closest to the centralized viewing point through the optical transmitter and the cable TV cable. The optical signal is converted into a radio frequency signal through the optical receiver and reaches the centralized viewing point through the coaxial network. , after demodulating with digital set-top box 19, output two kinds of signals of HDMI high-definition interface and AV video and audio interface, and provide the large-scale LED screen and 100-inch projector at the place of use. Since the optical cable and coaxial network are routed through long overhead and buried routes, in order to improve reliability and ensure the integrity of the live event signal, it is necessary to establish a hot backup signal channel.

Abstract

According to the broadcast television relay requirement, signals can be quickly switched on, and signal reliability guarantee needs to be made; a traditional method is that a person is sent to carry out routing inspection or signal source double-route backup; a multi-network hot backup mode is adopted, and a high-reliability and stability system scheme is achieved at low investment.

Description

technical field [0001] The invention relates to the technical field of radio and television, in particular to a radio and television relay emergency system based on multi-network hot backup. Background technique [0002] Traditional radio and television broadcasting usually adopts sending personnel to carry out route inspection or dual-routing backup of signal sources to ensure signal transmission. The manual method is inefficient and difficult to achieve reliable protection. When routing interruption occurs, it is difficult to recover quickly. Backup reliability is high, but the cost of each implementation is very high, and line construction needs to be carried out in advance, usually one week in advance. Both existing solutions have the disadvantage of high efficiency and low cost. Contents of the invention [0003] The purpose of the present invention is to provide a radio and television relay emergency system based on multi-network hot backup, which is used to solve th...
