Abstract

The invention relates to a high-definition SDI (Serial Digital Interface) digital video signal optical fiber transparent transmission device. The high-definition SDI digital video signal optical fiber transmission device comprises an SDI optical fiber transmission sending end and an SDI optical fiber transmission receiving end, wherein the SDI optical transmission sending end is used for converting an SDI high-definition digital video signal input by a user into an optical signal through signal processing, and transmitting the optical signal through an optical fiber medium; the SDI optical fiber transmission receiving end is used for receiving a high-speed serial optical signal transmitted by n optical fiber, reducing the optical signal into the SDI high-definition digital video signal through the signal processing, and outputting the SDI high-definition digital video signal to a video receiving end. The high-definition SDI digital video signal optical fiber transparent transmission device is compatible with the transmission of various SDI digital video formats, and has the advantages of high transmission instantaneity, large transmission bandwidth and high electromagnetic interference resistance.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a high-definition SDI digital video signal optical fiber transparent transmission device. Background technique [0002] Serial Digital Interface (SDI, Serial Digital Interface) is a standard for digital video transmitted on a coaxial cable. According to different resolutions, its transmission rate can reach 2.97Gbps, 1.48Gbps and 270Mbps, so SDI video can cover large Part of the video application fields from high definition to standard definition, in various industrial monitoring fields, SDI adopts uncompressed video transmission mode, so it has the advantages of high real-time monitoring, good image quality, and low transmission delay, and has become the mainstream in the industry. But in the signal transmission link, due to the demand of high-definition video, the increase of signal transmission rate will put forward very strict requirements on traditional cables, especi...
