In the monitoring video conference center, the command center will use a large screen splicing processor (LZ-HD**P**TV) and mixed matrix (LZ-HD**-**TV), especially the large screen splicing processor is the core equipment of the large screen splicing system, an important equipment is the control signal input and output matrix. There are differences in working principle and function between them.
1, the matrix and the working principle of the splicing processor difference
The matrix is a multi input signal switching output to a plurality of display devices, through the matrix signal switching function, rotate the display of different signal images. The type of matrix has VGA matrix, AV matrix, RGB matrix, DVI matrix, HDMI matrix, mixed matrix, etc..
Large screen splicing processor is provided with a switching function matrix, will also be a complete video signal is divided into N blocks allocated to the N display unit (such as LED, LCD, DLP, PDP), the display is composed of a plurality of input video display logic unit on large screen splicing. In general, the number and type of the input signal of the dragon and the big screen splicing processor depends on the user's needs. The signal matching of the adapter is very flexible and free, on a device, you can assemble a variety of models, including VGA cards, DVI cards, HDMI cards, SDI cards, CVBS cards, etc..
2, the difference between the processor and the matrix function
Because of the difference of the working principle, the difference of the two functions. Matrix can only be responsible for signal switching, can not handle, can not do the effect. Large screen splicing processor function is very powerful, with the matrix function at the same time, also can realize arbitrary windowing, roaming, overlay, scene preservation and rotation, the Dragon philosophy also has special effects in addition to the processor processor mosaic mask, video overlay, custom logo, intelligent detection system, multi screen interactive functions.
