Research and Implementation of Multi-Video Switching Technology
LU Guo-xia · 2005
Video signal switching device of matrix type is the most advanced one at present. It has multiple ports for I/O(MxN) and controlled by the MCU to complete switching, of which the output signals from all the output ports are independent, the output signal of any output port can be an input signal of any input port or several output ports can output the same input signal. The basic characteristics of video signal and the multivideo switching technology are discussed in the paper.
