Embodiment Construction

[0031] Various embodiments of the video signal backup method and system and the transmission method and system of the present invention will be described in detail below.

[0032] Such as figure 1 As shown, it is a schematic flow chart of an embodiment of the video signal backup method of the present invention, including steps:

[0033] Step S101: Establish a video signal channel between the signal source-signal processing board-display unit, and set it as the backup video signal channel of the main video signal channel, wherein the main video signal channel is signal source-main control board-display Video signal channel between units;

[0034] The signal processing board can be newly added, or a signal processing board already existing in the processor can be used. The video signal channel between the signal source-signal processing board-display unit refers to the video signal channel through which the signal source, signal processing board, and display unit are sequentia...

Abstract

A video signal backup method and system and a transmission method and system, wherein the backup method comprises: establishing a video signal channel between a signal source-signal processing board-display unit, and setting it as a backup video signal channel of the main video signal channel ; Divide the video signal of the signal source into the same two video signals, the first video signal is output to the main control board through the main video signal channel, processed by the main control board and output to the display unit for display, and the second video signal is through the backup The video signal channel is output to the signal processing board for synchronous processing; the status of the main control board transmitting the first video signal in the main video signal channel is monitored in real time; when the first video signal is lost, the video signal of the currently transmitted video signal is transmitted. The channel is switched to the backup video signal channel, and the signal processing board in the backup video signal channel outputs the synchronously processed second video signal to the display unit. The invention realizes signal backup and transmission.

Description

technical field [0001] The invention relates to the technical field of video signal processing, in particular to a video signal backup method and system as well as a transmission method and system. Background technique [0002] In the traditional splicing display technology, each display unit of the display system is equipped with a single desktop input main control board, and the main control board is connected to the signal source and the display device respectively. The main control board is used to process the received video signal of the signal source, and finally display it on the display device. [0003] Each display unit of the splicing display device has a large number of video signals input to the display system, so the working environment of the entire system will be very complicated. Once one of the signals fails, it will inevitably cause the corresponding display device to have a signal failure. Lost, resulting in black screen or other no-signal phenomena. Esp...
