Abstract

The invention discloses a synchronous display control method, device, and computer-readable storage medium. The synchronous display control method includes the following steps: acquiring a target field synchronous signal input to an interface machine and a target field synchronous signal output by a video decoding device in the interface machine. a first output field synchronization signal; comparing the target field synchronization signal with the first output field synchronization signal, and determining a second output field synchronization signal, so that the second output field synchronization signal is consistent with the target field synchronization signal ; Based on the second output field synchronization signal, synchronously display the video content corresponding to the video signal output by the interface machine on the sub-splicing screen corresponding to the interface machine, wherein the splicing screen includes a plurality of sub-splicing screens. The invention solves the problem of synchronous display of each sub-splicing screen in the splicing screen, so that each sub-splicing screen in the splicing screen displays video synchronously.

Description

technical field [0001] The present invention relates to the technical field of splicing screen video, in particular to a synchronous display control method, device and computer-readable storage medium. Background technique [0002] The usual large-screen display technology is realized by splicing display screens. The splicing display is also called a splicing wall, which splices multiple display screens (called display units) together as a super-large screen for image display. The video signal corresponding to each display unit (video signal unit, the data of these video signal units together constitute the video data to be displayed on the entire splicing screen) is output and displayed on the corresponding display unit after signal processing such as encoding and decoding. The video signals displayed by each display unit together form a complete display picture. However, how to realize the synchronous display of each display unit is an important subject and difficult pro...
