Description
Technical field
The utility model relates to the multimodal LED screen of a kind of support splicing apparatus, and it belongs to the video process apparatus class of large-scale high-resolution RGB LED display.
Background technology
Oneself becomes the sign of modernization, internationalized city large-scale high-resolution RGB LED display; It can play Word message, animated advertising, video image, day by day in advertisement, physical culture, traffic, finance, communication, commerce, all trades and professions such as perform in a radio or TV programme and obtained using widely.Because counting of present large-scale high-resolution RGB LED display reaches 7680 * 2160 even more; For this reason its to the resolution of the vision signal of front end require correspondingly also improved, the front end vision signal that resolution is low excessively can not make large-scale high-resolution RGB LED display give full play to the speciality that its high precision shows.In this case; In order to adapt to the needs of large-scale high-resolution RGB LED display; With the supporting video system of large-scale high-resolution RGB LED display in existing many cover transmitting systems that are widely used schemes of carrying out the signal transmission; In this scheme; Generally all be the DVI picture element signal to be loaded on every cover transmitting system point-to-pointly, if the resolution of vision signal that front end is imported into such as CVBS, SDI or DVI signal is relatively low, then need cut, amplification and synchronous processing the relatively low vision signal of these resolution.LED display video splicing apparatus promptly is an equipment of bearing aforementioned task.Described LED display video splicing apparatus comprises a preposition video processor and several rearmounted video processing units; The output port of each rearmounted video processing unit connects with the transmission card in use; Each sends the corresponding zone that drives a part of large-scale high-resolution RGB LED display of card; Preposition video processor is pressed the configuring condition that sends card and is respectively sent the actual physics resolution of blocking the large-scale high-resolution RGB LED display that drives; The ratio of carrying out to the vision signal of its input end is cut apart; Be loaded into each rearmounted video processing unit through the vision signal output bus then and zoom into needed resolution, card is sent in output then, sends card and drives certain local zone of its LED display of bearing by each; Each regional image collection forms a secondary high-resolution, very color intact video images, the process of splicing that Here it is.
Because the whole video image is each regional set, if each regional video image displayed is asynchronous, some regional image occurs earlier, occurs behind some regional image, and spectators will feel the situation of tangible Video Segmentation border and disconnected frame.This situation need do one's utmost to avoid; The problem of the existence of prior art is that its preposition video processor only cuts apart the vision signal of front end input in proportion; Directly be loaded into each video processing unit after cutting apart and carry out processing and amplifying; Such mode perhaps changes image slowly for the image of static state, can not occur clearly Video Segmentation border and the situation of disconnected frame basically; But when institute's images displayed dynamic change faster under the situation; Usually owing to the asynchronous situation that Video Segmentation border and disconnected frame occur, aforesaid problem is the problem that LED display video splicing apparatus must solve between each zone, but incomparable at present satisfied solution.
On the other hand, the LED display that LED display video splicing apparatus is faced in application process has varied, consists essentially of common splicing display mode and point-to-point splicing display mode.Under the common splicing display mode, be that vision signal is cut apart, amplified, be spliced into the pattern of a complete image again; This pattern of the many employings of present video-splicing device.Under the point-to-point splicing display mode; Divide two kinds of situation again, a kind of is that the LED display area is huge, and the arithmetic capability to front end host computer system can't satisfy its requirement greatly; Generally can only take to divide the viewing area in this case; The subregion makes playing material, and the mode of playing simultaneously then realizes point-to-point demonstration, and we are referred to as domain based mode; The area that second kind of situation is LED display is bigger, but the arithmetic capability of host computer system can satisfy the requirement that its high-resolution is play, and in this case, generally takes the form of extended desktop to realize point-to-point demonstration, and we are referred to as the extended desktop pattern.
Do not have the LED screen splicing apparatus of supporting above all functions pattern in the prior art simultaneously, brought bigger inconvenience to rig-site utilization.According to the above, obviously prior art has further improved necessity.
Summary of the invention
The purpose of the utility model is to provide the multimodal LED screen of a kind of support splicing apparatus, to overcome the problem that prior art exists.
The multimodal LED screen of a kind of support of the utility model splicing apparatus; Comprise some preposition video processing units, some rearmounted video processing units and control coordination unit; Said rearmounted video processing unit comprises signal input port and blocks joining DVI output terminal with the transmission of driving LED screen in use; Said preposition video processing unit comprises some video signal input terminal mouths and VT mouth; The VT mouth that it is characterized in that preposition video processing unit is connected on the input port of control coordination unit; Said control coordination unit comprises the bus-type output terminal, and said bus-type output terminal is received the signal input port of each rearmounted video processing unit, simultaneously each rearmounted video processing unit include one can with the direct coupled microchannel of the upper video source of front end signal input port.
The multimodal LED screen of this support of the utility model splicing apparatus; Can be operated under the multiple mode of operation; Under common splicing pattern and extended desktop pattern; The video signal input terminal mouth of preposition video processing unit connects with the upper video source of front end, and preposition video processing unit outputs to the control coordination unit after vision signal is handled, and said control coordination unit comprises parsing, the forwarding capability of control command; And the more important thing is that its outputting video signal to preposition video processing unit resolves and handle; Produce one group of video synchronization signal, and this synchronizing signal is loaded on each rearmounted video processing unit through the bus-type output terminal with vision signal, thereby can guarantee the frame synchronization property of the vision signal output of each rearmounted video processing unit through coordinating; The situation of Video Segmentation border and disconnected frame occur after thoroughly having solved splicing for this reason, thereby really realized seamless spliced.Under the domain based mode situation; The microchannel signal input port of said rearmounted video processing unit is connected to respectively on the upper video source of front end; Rearmounted video processing unit is handled the vision signal of appointed area according to the rule of setting within it; Output to the transmission card corresponding then, again by the respective regions that sends card output driving LED screen with it.Under this pattern; Because the output parameter of rearmounted video processing unit carries out regulation by the control coordination unit; For this reason, the control coordination unit can produce one group of synchronous reference signal according to the output parameter of the rearmounted video processing unit of its regulation, and said synchronous reference signal is loaded on each rearmounted video processing unit through the bus-type output terminal; For this reason, also can guarantee the frame synchronization property of final LED screen display frame to a certain extent.Obviously the purpose of the utility model is achieved in sum.
