[turn] Working Principle and Exception Resolution of Video Divider

In a video system composed of multiple video sources, a video switcher is usually used to display multiple images on one display device in turn. However, sometimes in order to allow the monitoring personnel to see all the monitoring points at the same time, multi video dividers are often used to display multiple images on one display device at the same time. When several multi video dividers are used, it is possible to display multiple pictures transmitted from all video sources at the same time with the same number of display devices as the multi video dividers. In this way, the number of display devices is reduced, and the monitoring personnel can monitor the situation of each part at a glance. The commonly used video dividers are four pictures, nine pictures and sixteen pictures.

Basic working principle of video divider:Using the methods of image compression and digital processing, several pictures are compressed on the screen of a display device in the same proportion. Some also have the function of built-in sequence switcher, which can output and display the full screen picture input by each video source in turn according to the sequence and interval on the display device (as switching the host to switch the picture in turn), and can be recorded by the video recorder according to the above sequence and interval. The interval is generally adjustable.1. Principle and function of video divider for monitoring equipment

In the security industry, the application of monitoring is the most common, and the video splitter is often used in the monitoring equipment. There are four, nine and sixteen video dividers, which can simultaneously display the images of 4, 9 and 16 video sources on one display device, or send them to the video recorder for recording. Multi video dividers are a common one. So what are the principles and functions of video splitter for monitoring equipment?2. Function of video dividerThe video divider is designed with modular functional units, adopts the latest special technology and special devices for image processing, and uses microcomputer control technology and digital image processing technology. The number of input and output of signal channels is customized on demand, which has very strong system flexibility and expansibility. It is the first high-tech product with hardware structure at home and abroad. Designed for large and medium-sized monitoring, dispatching and command centers!

Video dividers are widely used in telecommunications, railway, banking, campus, home and other fields. They have experienced the strict test of various environments and have been widely recognized by users. The performance and price of video divider are relatively good, and the quality and continuity of image can meet most requirements. 9 segmentation and 16 segmentation are expensive, and the resolution and continuity of each image will decline after segmentation, and the video effect is not good.3. Working principle of video dividerUsing the methods of image compression and digital processing, several pictures are compressed on the screen of a display device in the same proportion. Some also have the function of built-in sequence switcher, which can output and display the full screen pictures input by each video source on the display device in turn according to the sequence and interval, and can be recorded by the video recorder according to the above sequence and interval. The interval is generally adjustable.

Main performance:1. Fully compressed image, color / black-and-white video divider for digital processing.2. Four video inputs with four looped outputs.

3. Built in sequential switcher with adjustable time and independent switching output.Video Splitter FAQQ1: what is the correct product launch sequence of the Video Splitter?

First connect the standard power supply DC12V / 2a of the product to the product, then connect the output device to the output port of the product, and finally insert the input device.Q2: after the video splitter is connected to the product, the product will have abnormal flower screen and color?1. Check the wire quality, directly test the wire input and output equipment, and replace the wire quality problems;

2. Whether the wire is within the effective range, the longest input and output support the 15m range of HDMI cable, and the wire with amplification chip can go to a longer distance;3. Use the correct power on sequence;4. The output device only supports the HDMI interface device, and the DVI interface device will not display and spend the screen, because the HDMI default output contains audio information, and the subsequent DVI device does not accept audio information. Users who need VGA interface display can purchase mt-hv01 (HDMI to VGA signal converter) for use;

Q3: after the multi video splitter is connected to the product, the product will have the phenomenon of insufficient screen and over screen?1. By adjusting the input resolution of the computer and the zoom ratio of the graphics card control center, you can adjust it to the appropriate;2. The TV set connected by the user can use the remote control to adjust the picture ratio of 16:9, 16:10, 4:3 and point-to-point output, because the sub signal sources are 16:9, but many TVs may be 16:10. If they do not match, there will be problems of image offset and scaling.

Q4: what about the split screen phenomenon?1. Power off and restart to see if it is normal2. Determine whether the fixed port is irregular

3. It's the port. It's time to check the wire and internal problems of the product4. The irregular single screen is normal, and the screen flower screen and black screen can be sent back for upgradinglw
