Abstract

The invention provides a digital video light exchange transmission platform comprising a wave separator, an input interface unit, a light exchange matrix unit, an output interface unit, a wave combiner and a control unit. The wave separator is provided with a signal input end and a signal output end. The input interface unit is provided with a video signal input end, a control signal input end and a video/digital signal output end. The light exchange matrix unit is provided with a video/digital signal input end, a control signal input end and a signal output end. The output interface unit is provided with a video/digital signal input end, a signal output end and a control signal input end. The wave combiner (5) is provided with a signal input end and a signal output end. The control unit is provided with a first control signal output end, a second control signal output end and a third control signal output end. All ports are respectively and correspondingly in electrical connection. The digital video light exchange transmission platform carries out digital video fiber transmission through a network and has the advantages of high definition of transmission images, good real-time performance, rich interfaces and convenient organization of a private video network.

Description

technical field [0001] The invention relates to the technical field of digital optical fiber communication, in particular to a digital video optical switching transmission platform with digital video transmission and switching as its core business. Background technique [0002] The early video optical fiber transmission technology mainly used analog amplitude modulation, frequency modulation / phase modulation. Due to the poor anti-interference ability of analog signals, cumbersome multiplexing, poor transmission signal quality and high performance requirements for components, it was gradually replaced by digital replaced by video transmission technology. The common digital video transmission equipment is a point-to-point digital video optical transceiver. In addition to providing video transmission, this type of video optical transceiver can also provide audio and data access and transmission at the same time. In a relatively simple video surveillance system, this type of op...
