Method for realizing synchronous cooperated display on multiple sets of spliced display screens

Abstract

The invention discloses a method for realizing synchronous cooperated display on multiple sets of spliced display screens. According to the method, a splicing management server, a plurality of signal source node machines and at least two sets of spliced large screens are connected through Ethernet for forming a local area network, a display node machine is built in each unit display screen for forming the spliced large screens, input signals are converted into network data stream by the signal source node machines, the signal source node machines receive instructions of the splicing management server, cuts images into blocks and sends the images subjected to block cutting to the specified display node machines, the display node machines receive image data blocks for reduction display, meanwhile, a starting display instruction and signal information obtained through calculation are sent to the signal source node machine and the display node machines by the splicing management server, and parameter information, displayed on all spliced large screens, of signals of the signal source node machines are sent to the signal source node machines through Ethernet. The method has the advantage that the cooperated synchronous display and control among a plurality of spliced display screens can be flexibly and conveniently realized.

Description

technical field [0001] The invention relates to a display method of a display screen system, in particular to a method for realizing synchronous and cooperative display on multiple sets of spliced ​​display screens. Background technique [0002] In the existing large-screen splicing display system, the signals are switched to the upper screen through the matrix switcher. However, in many cases in actual splicing applications, there are usually multiple sets of large-screen display systems in one unit. Although the method of matrix and distributor can also realize signal sharing and simultaneous call and other similar functions, it is necessary to connect and distribute all the signals to be displayed on the large screen in advance. If this signal is to be connected to multiple sets If it is displayed on a large screen, the line must be connected in advance with a physical connection (usually a video cable such as DVI / RGB / CVBS). The hardware cost of this implementation is ve...

Although the method of matrix and distributor can also realize signal sharing and simultaneous calling and other similar functions, it is necessary to connect and distribute all the signals to be displayed on the large screen in advance. If this signal is to be connected to multiple sets If it is displayed on a large screen, the line must be connected in advance with a physical connection (usually a video cable such as DVI / RGB / CVBS). The hardware cost of this implementation is very high, and if a new signal is to be added , you need to add the corresponding connection, that is, rewiring and re-debugging, which is time-consuming, inefficient, and especially inflexible

If multi-signals are to be displayed synchronously and collaboratively among multiple sets of spliced ​​large screens, very complex signal linking and control must be performed. The method of implementation is to first convert the same analog signal into two channels at the source using a matrix, and then Into different splicing screens for display, the image quality and synchronization of the signal are not guaranteed

Moreover, the coordinated and synchronized display of multi-system signal display is even more difficult to manage. Even if the multi-screen sharing of a small amount of signals can be realized, it is difficult to achieve the coordinated and synchronized display on multiple sets of spliced ​​large screens.
