Video conversion board

At present, most kinds of video conversion board directly used frequency multiplication technology, convert the 50 HZ PAL signal into 100 HZ, and not really realized interlace scanning to progressive scanning conversion, the visual effect of these kinds of video conversion board is very clearly distinction compare with our products.

Video Presenter has been widely used recently , this is a new kind of multimedia equipment, it can be used for teaching and meetings. According to the types of video signal the Video Presenter can be divided into two categories: analog Video Presenter and Digital Video Presenter.

The phenomenon of image jitter, blinking, color distortion, the standard A4 page text and images blurred is ubiquitous.The reason is the resolution of analog camera is only about 470 TV lines, the capability of image and detail processing is insufficient.

Using this video conversion board:

① can be more effectively overcoming the shortcomings of signal jitter, blinking, fuzzy images, color distortion, the low resolution;

② digital RGB signal output , 1024 * 768 resolution, improved image clarity and resolution, with a lowrer brightness projector can achieve a satisfactory effect, can extend the life of the projector.

③ close to the visual effect of Digital Video Presenter, cost-effective, is the mainstream products in the past few years.

Signal Standard:

* use 5 V external power supply, the largest current consumption is 600 mA.RGB output signal is the standard 0.7V VPP, synchronization signal is standard TTL level.

Product features:

With enhanced image processing technology, can convert VCR VCD DVD video signal ---- composite video (CVBS), S-video (S-VIDEO) input signal into standard VGA / SVGA / XGA Signal accord with VESA.

Full-screen, true color images show, support any external display (CRT display or LCD projector) conversion output resolution of 640 X480 @ 60-75HZ, 800X600 @ 60-75HZ, 1024X768 @ 60-75HZ.

Flexible input mode

1. 2 CVBS and 2-S-VIDEO, 1 VGA

2. 6 CVBS, 1 VGA

3. 4 CVBS and 1 S-VIDEO, 1 VGA

Support external VGA input switch function, freely choose the image processing internal or the VGA input signal external

brightness, contrast adjustable;

Provide freeze function (especially suitable for video Presenter)

1. full-screen freeze

2. screen contrast function, (semi- screen frozen, semi-screen activities)

3. Quad split-screen contrast function ,(the screen will be divided into four regions, a region show activities images, and the remaining regions were each freeze an image, so on the screen can be compared four different images) provide 2-8 times digital zoom ,color/ black-and-white switch function, negative switch function, redefinition the function and the number of the keys according to the user’ need, user can custom LOGO.
