Digital video transmission is a communication method that people use vision to obtain information. Compared with other information transmission methods, digital video transmission is accurate, intuitive, and efficient. Due to the large amount of information transmitted by digital videos and limited bandwidth, the compression and encoding of videos, selection of transmission channels and network protocols, a

Medium M-path image video image input and N-path image output. N output video images can be connected to the MONITOR for real-time monitoring by security personnel, or to the hard disk recorder of the video recorder. Any path in N-way output image can come from any path in M-way image. The switching rule can be programmed in advance and controlled by the micro
Nowadays, the security monitoring system is not only a complex optical fiber analog monitoring system, but more dependent on the network-based video monitoring system. With the increasing development of science and technology, the demand for IP network video monitoring is also growing. Coupled with the huge system architecture, analog monitoring is difficult to m
I. Introduction With the development of the network, people have developed various services on the network platform, such as E-mail, TELNET, FTP, and WWW. These services are point-to-point data transmission; people prefer to hold video conferences, listen to live concerts, and watch live broadcasts on the Internet. These are data transmission from point to point or to point, and IP multicast is required) co
