Video matrix equipment based on optical fiber transmission

Abstract

The invention provides video matrix equipment based on optical fiber transmission. The equipment comprises a video matrix input end and a video matrix output end; the video matrix input end comprisesa first optical port and a processor, wherein the processor comprises a video coding module and a first receiving and transmitting module, wherein the video coding module is connected with a first optical port through the first receiving and transmitting module; the video matrix output end comprises a second optical port and a controller, wherein the controller comprises a video decoding module and a second receiving and transmitting module, wherein the video decoding module is connected with the second optical port through the second receiving and transmitting module; and the first optical port and the second optical port are connected through an optical fiber. The input end equipment and the output end equipment are two pieces of discrete equipment, the input end equipment and the outputend equipment both adopt an embedded scheme, and therefore, the coupling degree is greatly improved, and the equipment is smaller and more convenient to carry.

Description

technical field [0001] The invention relates to the fields of communication and multimedia, in particular to a high-speed and low-delay video matrix device based on optical fiber transmission. Background technique [0002] The video matrix refers to an electronic device that outputs M-channel video signals to N-channel monitoring equipment arbitrarily through the method of array switching. Generally, the input of the matrix is ​​greater than the output, that is, M>N. At present, the implementation methods of video matrix are divided into analog matrix and digital matrix, which are used in various monitoring places. Among them, the analog matrix means that the video switching is completed at the analog video layer, and the signal switching is mainly realized by a single-chip microcomputer or a more complex chip to control the analog switch. Digital matrix means that video switching is completed at the digital video layer. This process can be synchronous or asynchronous. T...

AI Technical Summary

Problems solved by technology

[0006] 1. Each separation device is independent and the coupling degree is not high

[0007] 2. Most of the digital video matrix network transmission is network dielectric, the transmission distance is short and the signal quality is poor

[0008] 3. When the digital video matrix is ​​used, it cannot meet the occasions where the number of display devices at the output end is insufficient but all input channels need to be monitored
