Surveillance video matrix system, network and cascade switch and band width adjustment methods of surveillance video matrix system

Abstract

The invention relates to the field of security and protection and surveillance video, and discloses a surveillance video matrix system, a network and cascade switch and band width adjustment methods of the surveillance video matrix system. The surveillance video matrix system comprises a high-speed bus and a processor, wherein video picture signals are directly converted into high-speed bus signals, encoding and decoding are not carried out, low latency is realized, data are not damaged or compressed in the transmission process, picture quality is high, video edition can be directly carried out, and secondary processing is needless. The surveillance video matrix system further comprises a photoelectric transducer, optical signals are converted into electric signals, input and output of various ports are supported, and seamless joint of anolog signals and digital signals is realized. As extension of the surveillance video matrix system, two optical fiber cascade panels are connected through optical fiber backbones, the optical fiber transmission advantages of large communication capacity and long transmission distance can be fully played, and transmission of any video can be achieved.

Description

technical field [0001] The invention relates to the fields of security and monitoring video, in particular to monitoring video matrix technology. Background technique [0002] The video matrix, also known as the video integrated platform, is an existing product, which includes a main chassis, which contains various service boards (main control board, input / output board, expansion board, cascading board, etc.), and each service board passes through the backplane high-speed bus connection. The product can be connected to various front-end and back-end devices to realize signal collection, transmission, storage and display, and can realize alarm at the same time, thus combining scattered monitoring, storage, and alarm equipment into a monitoring system. [0003] In order to realize the expansion of the monitoring video matrix system, the monitoring video matrix systems can be cascaded. In the prior art, there are mainly the following cascading methods: [0004] 1. Analog matr...

AI Technical Summary

Problems solved by technology

[0007] There is a problem: the video resolution processed by the system is too low to meet the user's current requirements for video clarity

[0011] Existing problems: optical matrix cascading, does not support video editing and processing, only plays the role of switching, can only be transmitted and switched, video editing and storage usually requires other conversion equipment, and cannot realize the docking with the original matrix system

[0014] There is a problem: in this cascade system, the data needs to be compressed (codec). Compared with the above two solutions, the image quality is poor and the delay is high
