Abstract
The invention discloses a multi-screen panoramic display and control method and system. The system comprises an LED playing control system, a DP/DVI conversion interface, a DVI distributor group, a plurality of transmission cards, and a plurality of LED display screens. The LED playing control system receives multiple paths of different types of signals and outputs multiple paths of DP signals to the DP/DVI conversion interface. The DP/DVI conversion interface converts the multiple paths of DP signals into multiple digital video interface (DVI) signals which are sent to the DVI distributor group. The DVI distributor group outputs multiple groups of DVI signals to the multiple transmission cards. The multiple transmission cards send the multiple paths of DVI signals to the multiple LED display screens. The multiple LED display screens display a panoramic display image. Through the scheme of the invention, the traditional LED content playing mode is greatly improved, thus the playing content is more simple, and the playing content can be switched only through operating one key by one person.
Description
Technical field
The present invention relates to display field, and in particular to a kind of aobvious control method and system of multi-screen panorama.
Background technology
LED full-color display screen technology has been widely used for the recording of TV station's news variety show, shows because LED is full-color
It is mostly more without piece that no matter display screen is installed and display precision is higher, and this also becomes technique and replaces tradition splicing most
Big feature, has also been doomed the market position that technique is not replaced, with LED full-color display screen it is more next in every field application
More extensive, market is to its content broadcast request also more and more higher；Sending out plus the flourishing of LED Small Distances display screen in recent years
Exhibition, the definition and resolution ratio more and more higher of display screen even more have higher requirement to the broadcast content of display screen.It is conventional
The broadcast mode of LED display, based on computer supply play signal, next computer of normal conditions can only control one piece of screen
Play out, if you have polylith display screen, that also must just increase multiple computers carries out content broadcasting control.This is also caused
LED display video playback becomes more difficult, and especially for performing in a radio or TV programme for hall in TV station's variety, more than ten pieces of LED show
Building for screen, can just set off out the spot effect of magnificent mansion, but if just seeming especially difficult using traditional control mode,
More than ten computers, more than ten people play out simultaneously, and manpower and materials input is larger, and in this case, we just cannot broadcast
Put with synchronous and linkage property material content, because so many people's operations, are just unable to reach synchronous broadcasting at all.
Existing computer player, such as Windows media player players, can only open one on computer desktop
Individual window is played out, it is impossible to issue multiple windows, let alone plays different content, controls different screens.Or picture
The player of perfect codec class, it can issue multiple windows, it is also possible to play different contents, but but cannot accomplish to play
The centralized management of content, it is unified to play, also just it is unable to reach our use requirement.
The present invention controls difficult, complex operation mainly for solving display screen conventional contents broadcast mode, under multi-screen
Manpower and materials input is excessive, the problems such as high cost.Using the New LED broadcast control system of our independent researches, separate unit can be allowed
Computer, outputs multiple windows, and each window can play different contents, is compiled to playing content by LED broadcast control systems
It is single, it is possible to achieve to play in content set more and manage, it is synchronous to play.The content broadcasting form of LED display is advised again
Draw, change traditional broadcasting form so that single personal computer can control multiple screens, and each screen can be played and differed
The content of sample, while the LED broadcast control systems provided by the present invention can realize synchronous Concentrated Control, without the need for too many manpower, only
Need one computer of a people, so that it may which realization is managed collectively to performing in a radio or TV programme all screens in hall, centralized Control is synchronously played.So
The broadcasting difficulty of LED display content is considerably reduced, while the input that uses manpower and material resources sparingly, is in LED industry technique
It is pioneering, and utilize significantly during display screen afterwards is played.

Description of the drawings
Fig. 1 is present system composition frame diagram
Fig. 2 is LED broadcast control systems composition frame diagram of the present invention
Specific embodiment
LED broadcast control systems (VS Tac represent that identical is looked like with media server) proposed by the present invention can meet height
The broadcast of end extra-large LED screen and the special-shaped screens of various LED needs, and predominantly various special application scenarios provide picture and process
Solution.LED broadcast control system set HD video playing device, picture splicing equipment, video input matrix device, often
The function of numerous equipment such as rule video processor, with superpower video processing capabilities.At the same time, the LED broadcast control systems can
It is its customized development according to certain particular demands of client, to meet the scene of Client application.
The LED broadcast control systems support that the full HD audio video synchronization in 4/6/8/12 tunnel is broadcasted, overall to support 1920 × 1080
× 4/6/8/12 picture synchronization high definition is decoded.Support that multiple signals are introduced simultaneously：LED broadcast control systems support HDSDI signals, component
The vision signals such as signal, S terminals, DVI/HDMI and VGA are introduced.Wherein, S-Video, composite video signal support 720 ×
576 resolution ratio, component signal, DVI/HDMI/SDI signals support 1920 × 1080i resolution ratio.
The LED broadcast control systems integrate broadcast, media picture design, broadcast the several functions such as planning management, Yong Huke
To be managed by local controlling interface and be broadcasted；Both the content for broadcasting third party's video can be managed, it is also possible to which management is broadcasted
The local material content designed by LED broadcast control systems.
Scheme proposed by the present invention is mainly used in the high-end display screens of LED, realizes that the key panorama of one man operation one switches, for example
The big pictures broadcast of other needs of the backgrounds and securities industry etc. such as stadiums, grand theater, stage, the live, canopy of the heavens of TV station
Scene.
