数 模矩阵概述（A summary of several matrix matrices） Any security system, the control device is the core, the video matrix is typical. It not only determines the capacity of the television monitoring system (the number of monitoring image), the system model (video network topology structure), system control mode, control network structure, coding rules) and the display mode (direct observation images, the temporal interval and the number of order), determine the TV monitoring system and other security subsystem integration way (not the relationship between visual information and images, the linkage of the various functions), or the unity of the security system of the operating platform (man-machine interface), especially by multimedia interface graphical management (GUI), its network interface can realize remote management security system. A good matrix can almost achieve all the functional requirements of the security system. Therefore, it can be said that familiar with the matrix is familiar with the security system, with the matrix can be flexible to form a variety of practical security systems. Video matrix is the embodiment of the application and promotion of TV technology in the field of real-time monitoring, and it is developed and developed in response to the progress of TV technology. To understand and explore the progress and development trend of TV monitoring technology and security technology, look forward to its future, and observe the video matrix to give a glimpse of the whole picture. Video matrix classic system logo The so-called classic system is the way to connect directly from camera to display, and the information flow of the system is a simulated video baseband signal. Television monitoring from several image one-on-one display, or order to hundreds of road or more images, must solve a problem is, switch and display the distribution of the large amounts of video information, and how to realize the video information resource sharing. With this, the dev
