Problems solved by technology

[0003] This method is still widely used in the current monitoring system. Due to the high price of the video matrix, the overall cost of the system is relatively high.
In addition, the added video matrix requires a lot of video wiring to connect the video optical transceiver and the video matrix, and the video matrix and the monitor, which increases the number of system wiring, thereby increasing the engineering volume and failure rate of similar projects
Due to the insertion loss of the video matrix, the video matrix added between the video optical transceiver and the monitor will also affect the quality of the restored analog video signal to a certain extent

Abstract

The invention relates to a multi-channel video optical transceiver system capable of realizing video output switching without an external matrix, which comprises an M-channel video optical transceiver sending end and an M-channel video optical transceiver receiving end. By adopting the system, video output at the receiving end of the multi-channel video optical transceiver system provided by the invention can be directly connected with equipment such as a large screen, a monitor and the like, thus saving expensive video matrix, significantly lowering fabrication cost of similar systems, and avoiding insertion loss of an analog video signal introduced by the video matrix; and output switching of the multi-channel video optical transceiver of the invention is carried out in a digital domain, thus being free from loss of a switching signal. Therefore, the multi-channel video optical transceiver system can avoid quality reduction of the analog video signal introduced by the video matrix.

Description

technical field [0001] The invention relates to the fields of optical fiber communication and security monitoring. In many applications of video optical transceivers, it is necessary to use video matrix devices in combination with video junction points such as monitoring centers. Generally speaking, these video matrices are relatively expensive, thus increasing the cost of the entire system. The video optical transceiver that can realize video output switching without an external matrix involved in the present invention can realize the main function of the video matrix on the basis of an ordinary video optical transceiver with only a small increase in cost. Therefore, the equipment involved in the invention can be directly used in many systems that originally need to use the video optical transceiver and the video matrix at the same time, thereby reducing the overall cost of the system. Background technique [0002] At present, in the application of video optical transceive...
