Led screen works business also see! HD monitoring must be fully covered front, center, back-end and transmission, display and storage and other links, its value can be apparent. However, the current high-definition monitoring market, most manufacturers can only provide high-definition camera-based single device, and a set of high-definition monitoring system if less TV wall decoding display, its value is running out.
The role of high-definition decoder
A complete high-definition monitoring system, must cover front-end, transmission, back-end and all aspects of the center, are indispensable. Among them, the front is responsible for high-definition image acquisition, transmission is responsible for high-definition image transmission, the back-end is responsible for high-definition image storage, the center is responsible for high-definition image display and business management. It can be said that a set of high-definition monitoring system, the real value to the user is reflected in the center of the image is high-definition display, and this is inseparable from the high-definition decoder. In the case of
HD decoder's main role is to receive front-end high-definition encoded images and decoding, and then through their own video output interface, such as HDMI / DVI / VGA / BNC, the output display to the TV wall. It is just a positive and negative process with the front-end camera, front-end camera input image, encoding; decoder to decode, the output image. In the case of
For the size of the project and the size of the central TV wall, HD decoder has two main applications:
For small-scale TV wall, such as 4/8/12/16 splicing screen, then the high-definition decoder can be independent as a display control device to complete the decoding output display.
For large-scale TV wall, display control equipment is generally analog matrix or digital matrix, then the HD decoder is mainly responsible for receiving network coding data and decoding, and then the decoded data as a matrix input.
