Problems solved by technology
In the prior art, a single board is used to process the video signal. Video switching often takes 1 to 4 seconds, the switching speed is slow, and the preview function cannot be provided. The so-called preview function means that the video signal can be seen before the video signal is switched. Switched video image
To sum up, the existing video signal single-board processing technology has the defects of slow switching speed and no preview function

The embodiment of the present invention discloses a video signal processing device, including: a switch synthesis circuit board, a console, a display terminal and at least two video processing circuit boards, wherein: the video processing circuit board includes a video processing circuit board for processing at least one video source The video processing circuit, and the video processing circuit is connected with the console; the switching synthesis circuit board includes a signal switching circuit, and the signal switching circuit is respectively connected with each video processing circuit board, and is connected with the The console is connected; the display terminal is connected with the signal switching circuit. The invention also provides a video signal processing method. The purpose of the present invention is to provide a video signal processing device and method, which can complete video signal switching within milliseconds without flickering, and also has a video image preview function.
Description
technical field [0001] The present invention relates to the technical field of video signal processing, in particular to a video signal processing device and method. Background technique [0002] In the occasions such as TV, LED display screen, dispatching video monitoring, security video monitoring, TV broadcasting video monitoring, etc., the remote control or console is often used to switch the video signal, and the video processing controlled by the existing remote control or console There is often only one video processing main board, that is, a single board. In the prior art, a single board is used to process the video signal. Video switching often takes 1 to 4 seconds, the switching speed is slow, and the preview function cannot be provided. The so-called preview function means that you can see the video signal before switching Switched video images. To sum up, the existing video signal single-board processing technology has the defects of slow switching speed and no...
