The system comprises a video processing board for receiving the multiple paths of high-definition video signals and processing the signals and a display device used for displaying the processed multiple paths of high-definition video signals outputted by the video processing board. According to the system, the received multiple paths of high-definition video signals are processed through the video processing board, then the processed multiple paths of high-definition video signals are outputted to the display device for displaying, and a purpose of displaying multiple paths of high-definition videos based on a single display device is realized.
Description
Technical field
The utility model relates to the video image technical field, relates in particular to a kind of system that supports that the multi-path high-definition vision signal shows.
Background technology
Because high-definition video signal has the advantages that data volume is large, requirement of real-time is high, so at present demonstration of high-definition video signal or can only single channel show, demonstration for the multi-path high-definition vision signal, common way is to be fixed to dwindle after the splicing to show again, perhaps relying on a plurality of display unit realizes, this shows size so that the user can not adjust each road video in real time, or the rotation picture etc.; Thereby so that centralized displaying is with high costs, very flexible, practicality are not strong, can not satisfy the demand of the application scenarios such as centralized displaying management.
The utility model content
The utility model provides a kind of system that supports that the multi-path high-definition vision signal shows.
According to the utility model embodiment, the utility model provides a kind of system that supports that the multi-path high-definition vision signal shows, comprising: be used for receiving multi-path high-definition vision signal and the Video processing integrated circuit board of processing, be used for showing a display unit of the multi-path high-definition vision signal after the processing of described Video processing integrated circuit board output.
Described Video processing integrated circuit board comprises: be used for to receive the multi-path high-definition vision signal input unit, be used for storage multi-path high-definition vision signal at least one memory, be used for described at least one memory carry out read-write operation read-write cell, be used for according to user's request the multi-path high-definition vision signal being carried out the video frequency processing chip of convergent-divergent and/or rotation and/or combined and spliced processing and the output unit that is used for the output multi-channel high-definition video signal.
Described video frequency processing chip comprises the chip that FPGA realizes.
Described input unit comprises for receiving and conversion at least one optic module from the vision signal of optical-fibre channel transmission.
Described at least one memory comprises DRAM.
What described output unit was exported is the multi-path high-definition vision signal that belongs to same shooting time.
The beneficial effects of the utility model are: by described Video processing integrated circuit board the multi-path high-definition vision signal that receives is processed, then the multi-path high-definition vision signal after will processing outputs on the display unit and shows, has realized showing based on single display unit the purpose of multi-path high-definition video.
Description of drawings
Fig. 1 is the system configuration schematic diagram of a kind of embodiment;
Fig. 2 is the structural representation of the Video processing integrated circuit board of a kind of embodiment;
Fig. 3 to Fig. 8 is respectively any convergent-divergent of 8 road videos that adopt a kind of embodiment realization, the schematic diagram of rotation combination.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by embodiment.
As shown in Figure 1, the system that shows of the support multi-path high-definition vision signal of a kind of embodiment comprises: be used for receiving multi-path high-definition vision signal and the Video processing integrated circuit board 10 of processing, be used for the display unit 30 that display video is processed the multi-path high-definition vision signal after the processing of integrated circuit board output.
As shown in Figure 2, the Video processing integrated circuit board comprises: be used for to receive the multi-path high-definition vision signal input unit 11, be used for storage multi-path high-definition vision signal at least one memory 15, be used for memory 15 carry out read-write operation read-write cell, be used for according to user's request the multi-path high-definition vision signal being carried out the video frequency processing chip 13 of convergent-divergent and/or rotation and/or combined and spliced processing and the output unit that is used for the output multi-channel high-definition video signal.When should be understood that specific implementation, the Video processing integrated circuit board can also comprise the interface corresponding with optic module.In the present embodiment, video frequency processing chip adopts FPGA(Field Programmable Gateway Array, field programmable gate array) realizes, input unit comprises for receiving and conversion at least one optic module from the vision signal of optical-fibre channel transmission, memory adopts DRAM, and what output unit was exported is the multi-path high-definition vision signal that belongs to same shooting time.
Among a kind of embodiment, system takes HD video by the multichannel camera and transmits by optical fiber, then by a Video processing integrated circuit board centralized management, processing, is realized showing in real time by a display unit at last.The Video processing integrated circuit board adopts FPGA as kernel processor chip, deposit the multi-path high-definition vision signal in DRAM, then read the vision signal that deposits in, according to user's request respectively these signals carry out the processing such as convergent-divergent, rotation, then the vision signal after will processing deposits the combination that DRAM carries out video flowing in, exports at last all video flowings to display unit; Thereby realize finishing based on the single display device functions such as any convergent-divergent of multi-path high-definition real-time video, synthetic, rotation.The processing such as convergent-divergent, rotation can utilize FPGA to realize, specifically can adopt convergent-divergent commonly used, rotation scheduling algorithm to realize.Be appreciated that, here DRAM can have a plurality of, input unit deposits DRAM in after receiving the multi-path high-definition vision signal, process for each road vision signal, that finishes dealing with puts into another DRAM, until this DRAM be filled with after with its output, this DRAM discharges to re-use simultaneously.To shown in Figure 8, to input 8 tunnel vision signals as example, the system of employing the present embodiment can realize any convergent-divergent to 8 road videos, the rotation combination function on the single display device such as Fig. 3.
To sum up, the system of the present embodiment has the following advantages: (1) can realize the combination in any splicing of multi-path high-definition real-time video; (2) amplification that realizes any single width picture or multi-picture is dwindled, even the rotation of picture; (3) can at the Real Time Monitoring of single display device realization multichannel picture, break through the technical barrier in centralized displaying field.
Above-described embodiment is of the present utility model giving an example, although disclose for the purpose of illustration most preferred embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and appended claim, various replacements, variation and modification all are possible.Therefore, the utility model should not be limited to most preferred embodiment and the disclosed content of accompanying drawing.
