What is the controller for the LCD video wall to enter and exit? Did you choose the right one?
When corresponding to a real-time screen display system, under normal circumstances, customers will ask how many signal processors are needed, which is actually controlled by the control that forms the screen.
Outside the screen, the most important display is the complete signal processing equipment, which also determines the function of the entire screen. At this time, we need to configure the signal processing equipment according to our needs.
Distributor: It is commonly used when there is only one signal and input to display a large screen.
According to the number of image screens, the corresponding distributors are 1 in 4 out, 1 in 8 out, 1 in 16 out, etc.
Matrix: came into being on the basis of the simultaneous distributor. The function of the matrix is more single, it supports a variety of signal source input, and can be displayed on a large screen.
For example, we have 3 computer signals that need to be displayed on the screen, the upper limit is 15 screens, and a 4-input 16 matrix can be configured to switch and display each signal at the same time.
The decoder is professionally used for the decoding of video surveillance signals on the screen, including the front end connected to the video screen machine.
In addition to the function of the matrix, it can also achieve the screen split display function, such as displaying up to 64 images in one screen. This greatly improves the arrangement of the screen pictures.
Image and video processor: In some large control room, in addition to simple and decoding functions, sometimes they can also enlarge the screen and screen functions,
such as enlarging a certain image on the screen and displaying another image on it, compared to decoders The function is smaller.
