HDMI matrix is also called HDMI video matrix; in simple terms, HDMI matrix is a multi-input and multi-output device that integrates HDMI distribution function and HDMI switching function. It can output multiple HDMI signals at the same time and distribute 1 HDMI signal into multiple outputs.
Common HDMI video matrices generally support panel switching control and infrared remote control switching control; some HDMI matrices support RS232 control, LAN connection control, SPDIF optical digital audio output, external IR infrared input, etc. In terms of HDMI version, most HDMI matrices support HDMI 1.4, and advanced ones support HDMI2.0; in terms of resolution, they generally support 1920*1080P, and some support 4K@2K.
Common HDMI video matrices include 4-input and 2-output, 4-input and 4-output, 8-input and 8-output, 16-input and 16-output, 24-input and 24-output, etc. They are mainly used between multiple hosts and multiple displays (splicing screens, etc.). According to the needs of different periods, they can quickly switch between hosts and displays without rewiring or replugging the hosts. For example, in a traffic command center, each intersection is a video input. When all intersections need to be monitored, you can choose 1:1 output. When you need to view the detailed conditions of a certain intersection, you can directly enlarge the screen through the spliced display to view it.
