With the rapid popularization of digital high-definition, high-definition signals such as "HDMI" are gradually becoming familiar to people, and HDMI matrices are becoming popular and widely used in upgrading and renovating multimedia video conferencing systems. In recent years, conference systems have become increasingly large, and matrix systems are gradually moving towards large-scale development. While constantly upgrading the number of channels, it is still necessary to ensure the stable operation of the system. The Cody large-scale HDMI matrix perfectly meets the above requirements and has been successfully used in multimedia video conferences at the Sino German School of Engineering, Zhejiang University of Science and Technology. It has recently passed the acceptance inspection.

The Kodi HDMI digital matrix adopts two types of structures: modular plug-in board and solidified compact board. The modular plug-in board structure adopts a "front+rear plug-in board method, modular design, and redundant dual power supply", greatly facilitating system maintenance, upgrading, and expansion. It is a high-performance intelligent matrix device specially designed for switching high-definition digital signals, used to switch various digital video input signals to any video output channel, with functions such as power outage on-site protection, HDCP, infrared, etc. Mainly used in monitoring television engineering, multimedia conference halls, large screen display engineering, television teaching, command and control centers, and other occasions. It can adapt to uninterrupted working conditions of 7x24 hours, with an average time between failures exceeding 30000 hours, providing a stable and reliable signal transmission switching center for the system.
