Abstract

The invention discloses a method and a system for displaying a spliced wall image. Correct display of the image on a spliced wall is guaranteed by a pre-view method in advance. The method comprises the specific steps of: storing a copy of collected image data in a video memory to make preparations for coating on the wall, storing a copy of image data in a memory, previewing the image in the memory by a local client or a remote client, displaying the image in the video memory on the spliced wall after confirmation without an error, therefore, the image displayed on the spliced wall is the previewed and confirmed image; the display accuracy is greatly improved; the user experience is improved; the preview and confirm work can be locally finished and remotely executed, and convenience is provided for operating personnel.

Description

technical field [0001] The present invention relates to the technical field of video wall image display, in particular to a video wall video display method and system. Background technique [0002] The multi-screen splicing display system is composed of multiple display units, so its volume is very large. The controller must rely on the display control unit of the PC to realize the correct display of various signal source images and the zoom adjustment of the image. After the signal source is displayed on the splicing wall, the controller can judge whether the displayed signal source is correct, whether the signal is displayed normally, whether the switching between signals is normal, etc. through visual inspection. If the signal is incorrect, the display of the signal image will be turned off first, and the signal image will be re-opened on the splicing wall. In order to obtain a good display effect, this requires: [0003] 1. The controller must be present at the display ...

AI Technical Summary

Problems solved by technology

[0003] 1. The controller must be at the display site, only in this way can judge whether the signal source is correct and whether the signal is displayed normally according to the display content on the splicing wall

[0004] 2. In some special occasions, such as the command of the army and the police, when it comes to confidential document images, it is required that the signal picture displayed for the first time on the splicing wall is correct. If the display is wrong, it will cause adverse effects

[0005] In practical applications, the signal graphics displayed on the splicing wall are often not the expected signal graphics due to the unskilled or improper operation of the control personnel. These wrong operations will bring disadvantages in some serious occasions. Customer Experience

At the same time, for the customer itself, it is very likely that the controller is not at the control site, so that the preview function of the image cannot be realized, and the display of the signal image of each signal cannot be known

For the above problems, the user experience of the product will be greatly reduced
