| Abstract: | This paper discusses the technology of computer's switching the video crosspoint array and expanding I/O channels of video in the system of watching by TV,namely,the video crosspoint array composed of DG884 that is switched by the single chip microcontroller and controlled from point to point by one microcontroller. A great number of I/O channels of video are expanded by microcontroller's communication to increase the number of collecting points and watching points. |
