Abstract
The invention discloses a method for real-timely mapping video signals of a mosaic display screen at a control terminal. An H.264 coding device is arranged before the input end of a image mosaic processor, one output end of the H.264 coding device is connected with the input end of the image mosaic processor, and the other output end of the H.264 coding device is connected with a control terminal computer via a network cable connected with the network signal input port of the control terminal computer. The invention has the following advantages that: the content of the large mosaic display screen, which is displayed on the software operation interface of the control terminal computer, is not transmitted back by the image processor but is transmitted back as signals taken before the input end of the image mosaic processor; since the acquired IP video steam is compressed, the code stream is small, the IP video steam can be recorded and played back when needed, and consequently, the invention solves the problem on how to remotely operate and manage the mosaic display screen, and realizes the window display of specified input signals on the large mosaic screen and the real-time display of the specified input signals on the virtual interface of the control terminal computer.
Description
Technical field
The present invention relates to the method that the vision signal on a kind of large-screen splicing display screen is shone upon in the control end realization, especially relate to a kind of method that realizes shining upon in real time vision signal on the mosaic display screen at control end.
Background technology
Existing large-screen splicing display screen is made up of a plurality of independently display screen units, and the driving of process stitching image processor constitutes the large-screen of a ultrahigh resolution, operates shows signal on the large-screen for ease; The software of control large-screen generally adopts service/client terminal structure; Service end generally is contained on the splicing processor, and client software is contained on the computer of control end usually, and client software has a virtual square frame with the mosaic display screen proportional zoom on the interface of control end computer; The user is at this virtual square frame uplifting window; Resize-window closes window, and on corresponding splicing large screen, also has corresponding action.Because the computer of control end and splicing large screen be not or not same space under many circumstances, this moment, operating personnel had no idea to see content displayed on the splicing large screen.In this case, common way is content displayed on the large-size screen monitors, passes back in several seconds on the operation interface of control end computer through the mode of taking out point sampling is separated.And in order to reduce the influence of image passback to the image processor disposal ability; The general passback to content displayed on the mosaic screen of control end computer on the function software interface; Show in several seconds refresh once and resolution very low; Can not see content clearly, can not record a video, bring certain difficulty for so actual the use.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that realizes shining upon in real time vision signal on the mosaic display screen at control end; In the situation of directly not seeing splicing large screen; Can remote operation control splicing large screen; And can be, and can record a video to interested content at the displaying contents of understanding in real time on the control end computer on the splicing large screen.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of method that realizes shining upon in real time vision signal on the mosaic display screen at control end; H.264 an encoding device was set before the input of stitching image processor; An output of described H.264 encoding device is connected with the input of described stitching image processor; Another output of described H.264 encoding device is connected with the control end computer through the network connection that is connected with the network signal input port of control end computer; The splicing Control Software is sent the instruction of two parts when the virtual interface uplifting window; Make the signal one road that gets into behind the encoding device be input to splicing large screen after delivering to the stitching image processor without handling directly to encircle out; Specification signal is shown on splicing large screen with corresponding ratio at assigned address; H.264, another road is through becoming the IP video stream signal behind the encoding device coding, and IP video stream signal IP video stream signal shows on the virtual window of windowing of the control end computer corresponding with the virtual screen of splicing large screen through Control Software decoder module decoding back in real time.
Described IP video stream signal is the vision signal by 64 road CIF images after the encoding device encoding compression H.264.
Compared with prior art; The invention has the advantages that the content on the splicing large screen that is shown on the software operation interface of control end computer; Not to send back last time from image processor, but the number of winning the confidence passback before the input of stitching image processor, because H.264 its compression efficiency is high; Code stream is little relatively; On general controlling computer, show that 64 road CIF images are no problem, the vision signal of 64 road CIF images can meet the demands to general splicing large screen, and the vision signal of CIF image also can see clearly image; The IP video stream signal can arrive on the computer of control end through network; The splicing Control Software is sent the instruction of two parts when the virtual interface uplifting window; A part is to the input signal of the control stitching image controller appointment display command of windowing; Specification signal is shown on mosaic screen with corresponding ratio at assigned address, and another part is to connect encoding device to obtain and specify input signal to obtain the IP video stream signal, because the IP video flowing that obtains is through overcompression; So code stream is little; Playback when being fit to its video recording and needs has so just solved the problem that splicing large screen is managed in remote operation, and the input signal of having realized appointment is in windowing demonstration and the real-time demonstration on the virtual interface on the control end computer on the splicing large screen.

Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure; A kind of method that realizes shining upon in real time vision signal on the mosaic display screen at control end; H.264 encoding device 2 of a conventional equipment was set before the input of stitching image processor 1; H.264 encoding device 2 output is connected with the input of stitching image processor 1; H.264 another output of encoding device 2 is connected with control end computer 3 through the network connection that is connected with the network signal input port of control end computer 3; The splicing Control Software is sent the instruction of two parts when the virtual interface uplifting window; Make the signal one road that gets into behind the encoding device 2 H.264 be input to splicing large screen 4 after delivering to stitching image processor 1 without handling directly to encircle out; Specification signal is shown on splicing large screen 4 with corresponding ratio at assigned address, and H.264 another road through becoming the IP video stream signal behind encoding device 2 codings, and the IP video stream signal shows on the virtual window of windowing of the control end computer 3 corresponding with the virtual screen of splicing large screen 4 through the software decode module decoding back of hub 5 backs through control end computer 3 in real time.
