Description
Technical field
The utility model belongs to technical field of video processing, is specifically related to a kind of multiple format video capture card.
Background technology
In the playing process of movie and video programs etc., relate to the video of multiple format, in order to adapt to the broadcasting of different-format video, adopt the processor of splicing, the video frequency collection card that the processor spliced adopts multiple different-format to play, backboard is connected by data/address bus, backboard passes through bus exchanging data, then splicing output card is connected to by data/address bus, a video frequency collection card can only play a kind of video of form, and the process that the information in video frequency collection card processes in backboard is complicated, signal and circuit intersect to some extent, easily get lines crossed or produce noise, processing speed is slow, its handling principle as shown in Figure 1.
Utility model content
The utility model, for the defect of prior art, proposes a kind of multiple format video capture card.
A kind of multiple format video capture card, one DVI-I video interface, 2nd DVI-I video interface, the 3rd DVI-I video interface, the 4th DVI-I video interface respectively with the first multiple format video acquisition chip, second multiple format video acquisition chip, 3rd multiple format video acquisition chip, the 4th multiple format video acquisition chip is connected, and above-mentioned multiple format video acquisition chip is connected with graphics processing unit, described graphics processing unit is connected and is connected with high speed connector, and described high speed connector is connected with mainboard.
Described graphics processing unit is FPGA graphics processing unit.
The structure of described multiple format video acquisition chip is: RGB, YPbPr, CVBS are connected with input selection switch unit respectively, and input selection switch unit is connected with three tunnel clampers, three tunnel clampers are connected with 10, three tunnel analog-to-digital conversion module, and three 10, tunnel analog-to-digital conversion modules are connected with graphics processing unit; TMDS0, TMDS1, TMDS2, TMDSC are connected with TMDS differential decoding unit respectively, and TMDS differential decoding unit is connected with graphics processing unit.
Described multiple format video acquisition chip is MST69 family chip.
The beneficial effects of the utility model: multiple format video capture card of the present utility model adopts 4 DVI-I input interfaces, each interface supports the collection of various video signal, 1 multiple format video capture card holds the function of tradition 4 kinds of video frequency collection cards: DVI, RGBHV, YPbPr, CVBS, user can configure the video source form of each passage of single deck tape-recorder voluntarily, has greatly saved the cost of complete machine and the flexibility of use.

Fig. 1 is traditional video frequency collection card structural representation.
Fig. 2 is video frequency collection card structural representation of the present utility model.
Fig. 3 is the utility model multiple format video acquisition chip structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1
A kind of multiple format video capture card, as shown in Figure 2, one DVI-I video interface, 2nd DVI-I video interface, 3rd DVI-I video interface, 4th DVI-I video interface respectively with the first multiple format video acquisition chip, second multiple format video acquisition chip, 3rd multiple format video acquisition chip, 4th multiple format video acquisition chip is connected, above-mentioned multiple format video acquisition chip is connected with graphics processing unit, and described graphics processing unit is connected and is connected with high speed connector, and described high speed connector is connected with mainboard.
Described multiple format video capture card and conversion line with the use of.
Described graphics processing unit is FPGA graphics processing unit.
As shown in Figure 3, the structure of described multiple format video acquisition chip is: RGB, YPbPr, CVBS is connected with input selection switch unit respectively, input selection switch unit is connected with three tunnel clampers, three tunnel clampers are connected with 10, three tunnel analog-to-digital conversion module, and three 10, tunnel analog-to-digital conversion modules are connected with graphics processing unit; TMDS0, TMDS1, TMDS2, TMDSC are connected with TMDS differential decoding unit respectively, and TMDS differential decoding unit is connected with graphics processing unit.
Described multiple format video acquisition chip is MST69 family chip.
Multiple format video capture card of the present utility model 4 DVI-I input interfaces, each interface supports the collection of various video signal, and 1 multiple format video capture card holds the function of tradition 4 kinds of video frequency collection cards:
DVI
RGBHV
YPbPr
CVBS
In user 1 road DVI video, 1 road RGBHV, 1 road YPbPr, 1 road CVBS video input situation, the splicing controller of conventional video capture card is adopted to need configuration 1 DVI video frequency collection card, 1 RGBHV video frequency collection card, 1 YPbPr video frequency collection card, 1 CVBS video frequency collection card totally 4 capture cards, and often open capture card all only with 1 road video interface, remain 3 road video interface wastes.
Adopt the splicing controller of multiple format video capture card then only to need configuration 1 capture card just can solve all problems, user can configure the video source form of each passage of single deck tape-recorder voluntarily, has greatly saved the cost of complete machine and the flexibility of use.
The embodiment of the above is only preferred embodiment of the present utility model, not limits practical range of the present utility model with this, therefore the equivalence change that all shapes according to the utility model, structure and principle are done, all should be covered by protection range of the present utility model.
