High resolution multi-machine large screen display synchronizing method

Abstract

The invention relates to a high resolution multi-machine large screen display synchronizing method and belongs to the technical field of data communication and image processing. According to the method, in a hardware system mainly formed by an intelligent control terminal, a database server for storing display objects, at least two graphic workstations and a multi-screen processing device, the synchronous playing display of assigned display objects is achieved through the steps of segmenting, configuring, operating, loading, synchronizing and displaying. The high resolution multi-machine large screen display synchronizing method can support extreme high resolution display, occupied resources are greatly reduced, and the requirement for hardware is lower. A display client side is regarded as a display tool, system-level bottom layer operation can be accessed, system resources which are not used are uninstalled, hardware losses are reduced, and thus the operating speed and the stability of the system are improved. In the existing hardware environment of large screen display, the problem of the insufficient processing capacity brought by outputting massive information to large screens to be displayed can be solved simply by adding the graphic workstations acting through low cost PCs.

Description

technical field [0001] The invention relates to a large-screen synchronous display method, in particular to a high-resolution multi-machine large-screen synchronous display method, which belongs to the technical field of data communication and image processing. Background technique [0002] With the continuous development of the information society, large-screen display has been widely used. With the increase of display resolution, the large-screen display system puts forward higher requirements for hardware, software and other aspects. Due to the high resolution of the existing large-screen display system, frequent system display problems often occur, so that the resolution has to be reduced to avoid various possible problems, but this affects the quality of large-screen display. [0003] To sum up, the high-resolution display of large-screen combination generally has the following difficult problems: [0004] 1) In terms of hardware, since high-resolution high-definition...

Problems solved by technology

[0004] 1) In terms of hardware, since high-resolution high-definition display needs to output a very large amount of information, the hardware requirements are particularly high, and it is difficult to obtain ideal display effects without using high-cost hardware;

[0005] 2) In terms of software, when the physical resolution of the large screen is high, it is difficult to achieve point-to-point high-definition display; because the birth and development of each front-end display technology is based on general applications, and basically does not consider the existence of application technology under ultra-high resolution Therefore, software such as FLEX has limited the display resolution. When the overall resolution exceeds the threshold, the excess part will not be displayed;

[0006] 3) In terms of controls, the large-screen display system usually needs to integrate various third-party controls. Since the browser cannot integrate controls with incompatible controls, but also integrates compatible controls in time, it is easy to cause problems such as unstable operation of the entire display system, such as When clearing some surveillance video control integrated controls, the browser cannot completely uninstall them, resulting in continuous increase in browser memory and CPU consumption. When the browser exceeds the acceptable threshold, it will crash, and the controls are not uninstalled cleanly. Various situations that may also cause the interface to intersect

As a result, not only the cost is significantly increased, but also the stability and compatibility are poor due to the complexity of the hardware system.
