With the development and integration of technologies such as big data and artificial intelligence, people's use of advanced multimedia devices is also increasing. How to solve the complex operation of multiple devices has become an urgent problem to be solved. Recently, Dalian Kedi's analog video and audio matrix, multi format matrix, RGB matrix and other products have successfully won the bid for the Xuzhou Civil Defense Procurement Project. With its leading technology and professional services, it has become a "stable, efficient, and convenient" application model in the industry.

Kodi Analog Audio Video Matrix is suitable for various systems that switch audio and video signals. Its products include pure video matrix, pure audio matrix, and analog audio and video matrix. The matrix adopts two types of structures: modular plug-in board and solidified compact, mainly used in emergency command systems, monitoring centers, broadcasting and television systems, video and audio conference systems, audio-visual education and other industries for displaying multi-channel video and audio signals. Matrix size 4 × 1~512 × 512, using "field inverse" switching; Video supports high bandwidth output; Audio supports balanced/unbalanced input and output; Having an external synchronization signal interface; Supports multiple control methods including RS-232, RS-422, RS-485, and TCP/IP; All technical indicators have been tested by authoritative departments; All meet or exceed the Class A standard for broadcasting and television; Can adapt to uninterrupted working conditions of 7x24 hours; The average time between failures is greater than 30000 hours; Provide a stable and reliable signal transmission switching center for the system.

The Dalian Kodi Kd MF series high-definition multi format mixed matrix not only provides users with more convenience, but also offers products with higher cost-effectiveness. It adopts FPGA array based pure hardware technology architecture: due to the lack of hard disk, maintenance free, and no operating system, it avoids the problems of industrial control system crashes, hardware conflicts, blue screens, and computer virus intrusion; Moreover, the startup speed is fast (<20 seconds), stable and reliable, and unexpected power outages will not cause equipment damage. It can be operated frequently to switch on and off. The input and output boards adopt a modular rear panel structure, which can flexibly configure different signal formats and quantities; The power and control boards adopt a modular front panel structure with dual power and dual control redundant hot backup, which improves the stability of the equipment. This matrix also supports hot swapping, which allows online upgrades, maintenance, and expansion to be completed by simply replacing or adding cards without power outage or changing wiring. The integration of signal interface and signal board solves the process bottlenecks that affect signal quality, such as virtual soldering and missed soldering, and reduces the number of fault points in the matrix. The design of air-cooled noise reduction temperature control greatly improves the stability of the equipment.

The modular plug-in structure adopted by Dalian Kodi RGB matrix was first used by Kodi in China, adhering to the internationally advanced design concept of "front door plug-in structure, redundant dual power supply, and dual control system", completely solving the signal quality and production bottlenecks of large-scale matrices. Front door plug-in structure: supports live plug and unplug modules, and there is no need to replace the entire machine or change the system wiring after the device is mounted. Only the corresponding matrix module can be replaced to complete matrix maintenance and upgrading, greatly facilitating system failures, maintenance, expansion, etc. Redundant hot backup dual power supply: Adopting a redundant hot backup design, the matrix system's chassis adopts a hot backup integrated switch power supply, and the dual power modules in the chassis work simultaneously, serving as hot backup for each other. When one of the power components fails, the other power pack automatically assumes all power supply to the system, ensuring the continuity of system operation and greatly improving the reliability of the system. Dual control system: The dual control system can be selected according to requirements, and the matrix controls the control system as the main and backup. When the main control system fails, the backup control system continues to support system operation without affecting the switching operation of the matrix system.

Dalian Kedi has been established for more than 10 years, and its products have been widely praised for their high end, efficiency, speed, and safety. The company strives to achieve every application project, regardless of size or distance. Kedi engineers must visit the site to survey and guide operations, and provide modern, humanized, and intelligent new experiences for various industries with the most serious service.
