Abstract

The invention discloses a video synchronous display method and system. The method is based on the method provided by the invention. When synchronous verification of the spliced screen is carried out,output frame synchronization of the video segmentation equipment is judged through rectangular stripes which diffuse outwards from a central point at a constant speed and are continuously circulated.The method is simpler and more intuitive, and can be easily judged only by human eyes, and when frames are asynchronous, the dislocation difference of stable movement exists at the splicing position of each display screen, so that not only is the mode of adding a timestamp or a frame stamp into a video avoided, but also the frame synchronization verification time of a user or a worker is reduced.

Description

technical field [0001] The present application relates to the technical field of video display, in particular to a video synchronous display method and system. Background technique [0002] Video splicing equipment is required in applications such as TV walls and multi-screen projections. It divides the input video signal in real time, and then synchronously outputs different images to different display devices. These divided images need to be frame-synchronized, so as to reduce the sense of tearing and dislocation between multiple images. [0003] The traditional method of judging whether each splicing screen is frame-synchronized is to play a video source with a time stamp or frame stamp, and after splitting through the video splicing device, the tester judges the time stamp or frame stamp by taking pictures continuously Whether they are the same, if they are the same, it means that the frame is synchronized, otherwise, it is not synchronized. [0004] The existing metho...
