Abstract

The invention provides a video signal switching matrix system which comprises an input output device, a service management device, a fusion device and a switch control device which are sequentially connected. The input output device comprises at least one video signal input interface and at least one video signal output interface; the service management device comprises a transceiving processing module, a buffer module, a primary framing module, a multipath data 8/10B encoding and decoding module and a serial-parallel interconversion module which are sequentially connected, and a frame re-unlocking module connected between the buffer device and the multipath data 8/10B encoding and decoding module; the transceiving processing module is connected with the input output device; the fusion device comprises a primary frame unlocking module, a fusion distribution module and a reframing module which are sequentially connected; the reframing module is connected with the serial-parallel interconversion module; and the fusion distribution module is connected with the switch control device. The invention solves the problems of multiple video specification access, coexistence of various types of transmission interfaces and signal switching.

Description

technical field [0001] The invention relates to the field of intelligent security and communication, in particular to a system for realizing signal exchange between video signal interfaces and a device in the system. Background technique [0002] As the video transmission solutions in the traditional security field are based on Ethernet cables and copper cables, with the rapid development of high-definition SDI and other technologies, the use of optical fibers is becoming more and more popular. And there are many kinds of video specifications, such as CIF, D1, standard definition, high definition, etc. In the case of the coexistence of new and old multi-service types and multi-interface types, an interconnected alley that can solve Ethernet, copper axis and optical fiber at the same time, The demand for mutual exchange systems is becoming more and more urgent. Contents of the invention [0003] In order to solve the technical problem that different types of video signal i...
