The invention provides a cascade display control method among multiple large-screen spliced image controllers. The method comprises the following steps that a, N paths of cascade input interfaces and N paths of cascade output interfaces are reserved as cascade interfaces by spliced image controllers, wherein N paths of input signals of the cascade input interfaces can be randomly switched to arbitrary N paths output in spliced signal output K paths (N is no more than K), and can synchronously be switched to N paths of output of the cascade output interfaces, and the spliced image controllers splice random N paths signals which can be switched to the N paths of output of the cascade output interfaces (N is no more than J) in the J paths of signals of the input signal interfaces; b, a control system switches the input signals of the spliced image controllers (1 to M) to the cascade output interfaces (1 to N), and switches the cascade input interfaces (1 to N) to the spliced signal outputs (1 to K) and cascade output interfaces (1 to N), so as to realize all-region roaming display of the separated spliced input signals in the large screen.
Description
Technical field
The present invention relates to many cascade display control methods between the large-screen splicing image controller; When the jumbotron splicing video wall of many image controller controls; For realizing that the organic scheduling of all kinds of picture signals on a logic large-size screen monitors curtain wall shows that the leap of different images signal demand between the different images controller shows.
Background technology
Giant-screen assembly wall system is widely used on commander's monitoring, centralized dispatching and the communication system of monitoring, telecommunications and the public place of entertainment of public security warning, point duty, power scheduling, government department.Be meant that by projector, liquid crystal or LED display be display unit, the video wall that high brightness, high resolving power, the colour of forming through image controller enriches.This systemic-function is powerful, can show various computing machines (workstation), network signal and various vision signal, and through the centralized control of image controller, all kinds of pictures can be windowed arbitrarily, roamed, stack and convergent-divergent.Image controller is the nucleus equipment in the large-screen splicing system.So the image information in the total system is all passed through various channels and is pooled to the image controller processing, and then gives display part with it process result and assign to appear.Image controller has multipath VGA or DVI output, and the output of every road is connected to a display unit, and with the part of display frame, all unit are stitched together and have just constituted a big picture.
Form the nucleus equipment image controller of large screen system, the output channel of single device is limited, for example can only support 16 the tunnel, the 32 tunnel or higher.In large-scale large-screen splicing display system, often constitute spliced display wall by numerous display devices, the large-scale splice displaying system that adopts maximum 180 LCDs to constitute is arranged in practical application.The processing of separate unit image controller and fan-out capability often can not be supported so numerous display unit simultaneously.In practical application, for realizing the demonstration of numerous vision signal pictures in large-scale large-screen splicing system, image controller often adopts following several method:
1, distributed image control, the image controller system has numerous cell picture controllers to constitute, and the image controller of each unit is only supported a display unit, and the network that passes through of the image controller of different units connects.This type of control method can solve the centralized control problem that the splicing system image shows; But because the bandwidth of Network Transmission is present; If the shows signal of splicing system has the high-definition signal of numerous high bandwidth requirements to constitute; The mode of Network Transmission is difficult to carry enough bandwidth, is realizing that striding of unlike signal frame losing can occur when screen roaming stack shows, picture shows phenomenons such as hysteresis.
2, local control mode, this mode are that whole big screen system is controlled by many image controllers, and the signal between the different images controller can not freely be dispatched, and every image controller is only accomplished the control of self supporting the part display unit.This type of control mode is actually big screen system is cut into a plurality of subsystems of being made up of different controllers, does not organically get in touch between each system, separately independent operating.
3, the technological control mode of empty screen; This mode is accomplished by the image controller that adopts empty screen technology; Through network mode various signals is accomplished in image controller and to be compiled, empty screen technology is made up of the video card of a plurality of bulls outputs, and the display unit quantity of the big screen system that can form receives the present situation of the video card quantity that image controller can support; All simultaneously picture signals are through the pci bus of Network Transmission to image controller, and the processing power of system receives the restriction of pci bus bandwidth.
In above-mentioned 3 kinds of control modes, the highest with the transmission signals bandwidth of the mode of 2 (local control modes), display effect is best, but its signal between the different images controller is freely dispatched and had very big defective aspect the demonstration.
Summary of the invention
The purpose of this invention is to provide many cascade display control methods between the large-screen splicing image controller; Be on the local control mode basis of traditional large-screen splicing system; The signal that solves between the different images controller is freely dispatched the problem that shows; Advance ultra-large type large-screen splicing display system to be widely used, the solution of high-quality is provided for commander's monitoring, centralized dispatching and communication system.
Realize that technical scheme of the present invention is: comprise the following steps:
A. the stitching image controller reserves N road tandem incoming interface and N road tandem outgoing interface, as subtending port, wherein
