Video data superposition regulator is designed for the dynamic design of highway toll video stack equipment. It can be added to the video image in the driveway, number, name of the car, and the information such as the entrance. Each device with video input, all along two video output, no superposition superposition video output and along the road standard RS232 interface. Standard rs-five 232 interface with highway management information system, make record fee status information in real-time image data. When the power supply, two VDM superposition video output will be transferred to road without character, this image is stacking correctly.

Input signal can be surveillance cameras, VCD/DVD video signals, such analog video data after the signal superimposed device stack characters can be directly output to television, monitor or TFT LCD etc. This data is available through video superposition PC control software optional setting attributes and display content, character position, effect, From the PC or power, can save the last set of modules.

Second, the products are mainly features:
1, have two kinds of internal and external synchronous way to work

Data synchronization with internal and external video superposition of two kind of work, which is mainly used in synchronization video input can be selected, in the background color of the Chinese characters, to display color under the background color and characters were black and blue color, red, purple, green, red, yellow and white blue-green eight, The work is used for synchronization and video input character, adding to the video on the characters of gray level can be eight.

2 and many display effect

Video data display a variety of superposition instruments, including normal display, background, character that fills flashing, background and character and display, filled with black characters display. In addition, the content that is centered on the right and left, three display mode.
After the power not to lose information, video data can be preserved superposition information to the embedded FLASH, next after startup automatically preserve information, can save a full screen information (12 * 24 = 288 Chinese/characters). Supports both NTSC and PAL colour.

3, rapid display

Embedded within 24 x 24 bitmap fonts (gb first and second GB2312-80), every time when the PC software that send video data, Chinese code that can be immediately superposition device, speed, without time delay.

4 and multiple font, font effect

Through changing the different sound chip, can make the superposition of song typeface, kai ti, bold and end, such a different font, also can appear bold and italic type etc. After the election, through the font for PC can make font stroke has four different degree of adjustment, also have 1 times as high as wide, 1 x 1 x 2 times as high as wide, 2 x 2 times higher twice the width of high x 4 times as wide as four size selection.

5 and the date, time and temperature display

Video data can display the current stack is the date, time and its working temperature environment.
