The invention discloses a matrix switching
system and a matrix switching method for switching among multi-format video signals. The
system comprises an
optical fiber emission convertor, an optical matrix main unit and an
optical fiber receiving convertor, wherein the
optical fiber emission convertor is used for recognizing and converting the multi-format video signals into unified optical signals, emitting the optical signals to the optical matrix main unit, and receiving reversely transmitted optical signals to form
control data; the optical matrix main unit is used for fulfilling conversion and transmission of the video signals, synchronously converting the
control data corresponding to the video
signal into optical signals in the video
signal conversion and transmission process, and reversely transmitting the optical signals to the optical
fiber emission convertor; the optical
fiber receiving convertor is used for converting the optical signals transmitted by the optical matrix main unit into video signals taking the format of recognizable electrical signals of backward stage display equipment. The matrix switching
system and the matrix switching method have the advantages that the signals of the input-output paths are mutually independent, so that when one path of signals get out of order, the transmission of other paths of signals can be prevented from being impacted; meanwhile, the problem that the transmission of the control signals requires a special cable can be solved effectively as reverse data are synchronously transmitted in optical fibers.
