Abstract

The key ideal of the invention is: the central processor uses address bus, data bus and control switch logic to connect network module and receives the network video information from it; after decompressing, the received network video information is displayed on the display screen. The central processor is connected to the three-dimensional rocker and functional key.

Description

technical field [0001] The invention belongs to a monitoring and control device in the field of digital monitoring, in particular to a computer network to obtain the compressed digital video at the front end, decompress it and display it on the display screen on the device, and can control the front end cloud platform through the network. Controlled network surveillance video display system. Background technique [0002] At present, the wave of digitization of monitoring products has hit, and various network video servers, network high-speed balls, network cameras and other front-end equipment emerge in an endless stream. The monitoring system based on network digital video overcomes the limitations of analog closed-circuit television. It has a long transmission distance and can With the advantages of multiplexing with existing computer network wiring, strong anti-interference ability, simple addition, deletion and modification of monitoring points, and convenient query, it ...
