Difference between matrix and stitching processors

Many friends have confused the stitching processor with the matrix, so what is the difference between the stitching processor and the matrix? In video conferences, monitoring centers, and command centers, large-screen splicing processors and hybrid matrices are used, especially large-screen splicing processors. They are the core equipment of the entire large-screen splicing system. The matrix is also an important device for controlling signal input and output. There are differences in working principles and functions between the two. Below we briefly introduce the differences between matrix switchers and large screen splicers:

First, the principle difference

1. Matrix is used to switch and output multiple input signals to multiple display devices. Generally speaking, the number of input signals is greater than the number of output signals. For example, we want to monitor the signals from 100 cameras on 9 monitors at the same time, and we can use a matrix to implement the signal switching function of the matrix to display different signal images in rotation. The types of matrix are VGA matrix, AV matrix, RGB matrix, DVI matrix, HDMI matrix, mixed matrix and so on.

2. The large screen splicing processor divides a complete video signal into N blocks and assigns them to N display units (such as LED, LCD, DLP, PDP). In this logical large screen spliced by multiple display units Display of input video on. In general, the number and type of input signals of the large-screen splicing processor depends on the user's needs, and the number of output signals is equal to the number of display units. The signal matching of the splicer is very flexible and free. On one device, multiple types of boards can be assembled, including VGA boards, DVI boards, HDMI boards, SDI boards, CVBS boards, and so on.

Functional differences

1. Due to the difference in working principles, the functions of the two are different. The matrix can only be responsible for the switching of the signal, it cannot process it, and it cannot do any effect. The large-screen splicing processor is very powerful. With the matrix function, it can also achieve any window opening, roaming, superimposing, scene saving and rotation.

2. The functions of matrix and large-screen splicing processors are different, and they play different roles in system integration engineering. Users can choose according to their needs, and the two can also be controlled jointly.
