12G-SDI ultra-high-definition video optical transmitter and receiver

Abstract

The invention relates to a 12G-SDI ultra-high-definition video optical transmitter and receiver. The 12G-SDI ultra-high-definition video optical transmitter and receiver comprises a 12G-SDI transmitting end, used for transmitting 12G-SDI ultra-high definition digital video signal input by a user into an optical signal through signal processing, and the optical signal is transmitted through an optical fiber medium; a 12G-SDI transmission receiving end, used for receiving the high-speed serial optical signal transmitted by the optical fiber and reducing the optical signal into 12G-SDI ultra-high-definition digital video signal through signal processing, and outputting to corresponding equipment. The 12G-SDI ultra-high-definition video optical transmitter and receiver is compatible to ST-2082/1, SMPTE 424M, 344M, 292M and 259M standards, and 4K/60fps ultra-high-definition video can be transmitted in a non-compression mode. The transmission bandwidth reaches up to 11.88 Gbps, and meanwhile the 12G-SDI ultra-high-definition video optical transmitter and receiver has the advantages of being good in transmission real-time performance, long in transmission distance and high in anti-interference performance.

Description

technical field [0001] The invention relates to the field of signal transmission and communication, in particular to a 12G-SDI ultra-high-definition video optical transceiver. Background technique [0002] The SDI interface is an acronym for Serial Digital Interface, and is a digital video interface standard developed by the SMPTE (Society of Motion Picture and Television Engineers) organization, the Society of Film and Television Engineers. Since the SDI interface adopts the uncompressed video transmission mode, it has the advantages of high real-time monitoring, good image quality, and low transmission delay, so it is widely used in broadcasting, television, video surveillance and other fields. At the same time, because most of the SDI signals use BNC coaxial cables, which have the characteristics of low loss and strong anti-interference, so the transmission distance is generally 100 meters or more. [0003] With the continuous development of film and television technolog...
