Abstract
The utility model relates to video interface format conversion equipment. The conventional video interface format conversion equipment has simplex function and low integration level. The video interface format conversion equipment comprises a visual input module, a front end video A/D (analog to digital) conversion module, a core processing module used for adjusting video format and dimension alternation, a rear end video D/A (digital to analog) conversion module, a DDR (double data rate) memorizer and displaying resolution selection buttons. Video signals with different formats input from the visual input module is converted into digital video signals through the front end video A/D conversion module, the digital video signals processed by the core processing module is output to the rear end video D/A conversion module, the DDR memorizer is connected with the core processing module, and the displaying resolution selection buttons are connected with the core processing module. By adopting the video interface format conversion equipment provided by the utility model, a plurality of interfaces can be converted into a unified VGA (video graphics array) interface, so that the common display can support numerous video interface formats, and the VGA can be used at numerous occasions such as video surveillance or household entertainment.
Description
Technical field
The utility model belongs to the video communication technology field, relates to a kind of video interface format conversion equipment, and particularly a kind of video conversion multiple interfaces form and resolution format becomes the VGA video signal equipment of general DB15 interface format.
Background technology
The video signal interface form is varied in the market, the VGA interface format of analog interface such as bnc interface, S terminal interface, RCA RCA connector, DB15 etc., and digital interface has interface formats such as DVI.The VGA display as the video image display device always by singlely as the Special Display of PC computer.Along with popularizing of PC computer, every household all may be equipped with a computer; CRT monitor is in the past eliminated by LCD at present basically.The cost of a VGA display is very low, and usually, the resolution that VGA shows is all greater than the resolution of common monitor.Use VGA display (no matter being that former CRT VGA shows or the liquid crystal display) effect of display image generally to be not less than the display effect of common monitor.Therefore, rational and efficient use VGA display device can effectively be saved resource.But the DB15 interface format is only supported in common VGA demonstration.
Summary of the invention
The utility model provides a kind of video interface format conversion equipment at the deficiencies in the prior art.This equipment can show the vision signal of distinct interface form on common VGA display; The video of different resolution can also provide the function of video image size conversion for the user, so that can be shown to fixing VGA display.
The utility model comprises video input module, front end video a/d modular converter, the core processing module that is used for adjusting video format and size change over, rear end video d/a modular converter, DDR storer and display resolution selector button.
Convert digital video signal from the vision signal of the different-format of video input module input to through front end video a/d modular converter, this digital video signal exports rear end video d/a modular converter to after core processing module is handled; The DDR storer is connected with core processing module, is used for the intermediate result of buffer memory video processing procedure, and the display resolution selector button is connected with core processing module.
Described video input module comprises the RCA interface of bnc interface, simulation S_ terminal, simulation VGA interface, digital DVI interface and simulation YPbPr.
Described front end video a/d modular converter realizes that analog composite bnc interface video conversion becomes digital video, simulation S_ terminal video conversion to become digital video, simulation VGA interface video conversion to become digital video, digital DVI interface video conversion to become the RCA interface conversion of digital video, simulation YPbPr to become digital video.
Described core processing module is to have integrated between video format the programmable logic chip of conversion and video image size change over function.
Described rear end video d/a modular converter realizes that digital video converts the video of simulation VGA form DB15 interface format to.
The utility model with DB15 interface format output analog video, outputs on the VGA display after the analog video that receives is carried out video format conversion and video image size conversion.This equipment can make single computer VGA show and support composite video, component vide or digital video etc.Can finely enable display not only as single computer VGA display, can also be as the display device and the more high-resolution DVI interface format video signal displaying apparatus of support of monitor and DVD broadcast.
The utility model has following beneficial effect with respect to prior art: this uses novel realization BNC, S terminal, RCA, DB15 and DVI interface conversion to become unified VGA interface, VGA make common display support numerous video interface forms, so that can be applied in numerous occasions such as video monitoring or home entertaining.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises video input module 1, front end video a/d modular converter 2, the core processing module 3 that is used for adjusting video format and size change over, rear end video d/a modular converter 4, DDR storer 6 and display resolution selector button 5.
Convert digital video signal from the vision signal of the different-format of video input module 1 input to through front end video a/d modular converter 2, this digital video signal exports rear end video d/a modular converter 4 to after core processing module 3 is handled; DDR storer 6 is connected with core processing module 4, is used for the intermediate result of buffer memory video processing procedure, and display resolution selector button 5 is connected with core processing module 4.
Video input module comprises the RCA interface of bnc interface, simulation S_ terminal, simulation VGA interface, digital DVI interface and simulation YPbPr.
Front end video a/d modular converter realizes that analog composite bnc interface video conversion becomes digital video, simulation S_ terminal video conversion to become digital video, simulation VGA interface video conversion to become digital video, digital DVI interface video conversion to become the RCA interface conversion of digital video, simulation YPbPr to become digital video.
Core processing module is to have integrated between video format the programmable logic chip of conversion and video image size change over function.
Rear end video d/a modular converter realizes that digital video converts the video of simulation VGA form DB15 interface format to.
Wherein, core processing module can be LX16-2CSG324 or other electrical specification integrated circuit similar to it of U.S. XILINX company; Rear end video d/a modular converter can be THS8200 or other electrical specification integrated circuit similar to it of American TI Company; Front end video a/d modular converter can be ADV7401 or other electrical specification integrated circuit similar to it of U.S. AD company.
Can be understood by above-mentioned explanation, by video interface format conversion apparatus of the present utility model, common VGA demonstration can be used as outside the present PC computer monitor, can also support the vision signal of different resolution and distinct interface form.This equipment can effectively be saved the cost of video demonstration and upgrade the existing VGA demonstration of upgrading and make its support bigger resolution and multiple different video playback apparatus.
