The display part of TV monitoring system includes video switcher and monitor guide. The function of video switcher is to switch, repeat, process and copy the image signal transmitted by the system. It can automatically or manually control multiple video signals, so that a monitor can monitor multiple camera signals.
video matrix switcher
Video matrix switcher is an electronic device that can arbitrarily output M-channel video signals to n-channel monitoring devices by array switching. Generally, the input of matrix is larger than the output, i.e. m > n. Some video matrices also have audio switching function, which can synchronously switch video and audio signals. This kind of matrix is also called video-audio matrix switcher. At present, there are two kinds of video matrix, analog matrix and digital matrix. Video matrix switcher is generally used in various monitoring occasions.
If you have 70 cameras, but only 7 monitors, then the matrix allows your monitor to cycle through 70 cameras.
In short, the matrix host is mainly used with the TV wall to complete the function of picture switching. But the common matrix input (camera) is 16 times, output (monitor) is 4 times; AD matrix is the originator of video switching matrix in the United States, and the first video switching matrix in the industry is from AD. So far, analog video switching matrix in the market basically refers to the circuit design of AD matrix. Accounting Architecture.
