Abstract

The invention discloses a synchronous rapid display switching method for a television wall and decoding equipment, belongs to the technical field of display and aims to solve the technical problem that monitoring areas on the television wall cannot be switched synchronously and rapidly after a client sends a switching command. The synchronous rapid display switching method for the television wall comprises the following steps: receiving the switching command, wherein the switching command comprises channel information of a channel to be displayed and a display area; before switching time arrives, preprocessing video streams of the channel to be displayed corresponding to the channel information; and when the switching time arrives, putting all the video streams of the channel to be displayed corresponding to the preprocessed channel information to the display area at the same moment.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display method and a decoding device for synchronously fast switching of a video wall. Background technique [0002] In the field of video surveillance, a video wall often needs to display images from multiple network cameras and other front-end monitoring points. If the TV wall cannot display images from all monitoring points at the same time, it is necessary to perform a round-robin display operation on the images from each monitoring point. [0003] The current round-robin operation generally has the following two methods: [0004] Method 1. Configure the round-robin monitoring points, round-robin order, switching time and other round-robin elements that need round-robin to the decoding device that controls the display of the TV wall at one time. The decoding device performs round-robin pictures according to the pre-configured round-robin elements. to switch the display. ...
