Abstract
A matrix switcher is provided. A code rate of an ultra-high-definition video signal is reduced on the premise that the quality of the ultra-high-definition video signal is not affected through performing a Color Space Conversion (CSC) process and/or a Digital Stream Compression (DSC) process on the ultra-high-definition video signal at the transmitting side chip, thereby reducing a bandwidth required in conversion, switch and transmission of the ultra-high-definition video signal. A matrix switch chip with a low cost and general performance is used. Then, a corresponding DSC data decompression process and/or CSC process are performed at the receiving side to recover the performance of the ultra-high-definition video signal.
