Multi-signal input and multi-image composition device and method

Abstract

The invention discloses a multi-signal input and multi-image composition device and method. The device comprises input ports, signal conversion modules, a signal matrix switching module, a controller, an editor with a user operation interface, a signal decoder, a multi-image information superposition module, and a monitor, wherein the monitor is provided with a plurality of image monitoring windows. The device and method provided by the invention have the advantages that multiple video signals are simultaneously input, video caption information corresponding to each video is edited through the editor, each image monitoring window of the monitor is simultaneously bound with the corresponding video and the video caption information corresponding to the video, and each video and the corresponding video caption information are finally simultaneously displayed in the corresponding image monitoring window of the monitor, so that a user can visually monitor video contents played in the corresponding image monitoring window through the corresponding video caption information in the monitor.

Description

technical field [0001] The present invention relates to a technical field of video processing, in particular to a multi-signal input multi-picture preview editing device and method. Background technique [0002] LED display work site often requires multi-screen switching to switch multiple images to the LED display. These images generally come from multiple on-site cameras, or pre-programmed video programs, or images played by computers. These video signals There are sometimes as many as a dozen sources; these image program sources do not have a unified synchronization mechanism, nor do they have a consistent format. If they are directly switched between these signal sources, it will cause the subsequent video processing unit to have a second-level short-lived The timing is chaotic, and it goes through the process of re-identifying the input signal format and re-establishing the timing, and this process will lead to abnormal display of the picture on the LED screen, such as ...

AI Technical Summary

Problems solved by technology

The problem with the existing technology is that the director cannot quickly select the desired signal source. For a live program, because multiple signal sources may come from cameras with different angles, only multiple scenes on the scene can be monitored by the director at the same time. Under normal circumstances, the director can capture the ideal picture in real time, but the existing LED video switcher cannot allow the director to see all the pictures at the same time. It is difficult to capture the real-time wonderful moments of the program scene, and it is obvious that the existing technology needs to be further improved.
