With the changes in people's work methods and concepts, visualization systems have become an excellent means to effectively improve business management and operation, and many conference halls are gradually moving from single functionality to multifunctional. For many years, Kodi products have been widely used in broadcasting and television engineering, multimedia conference halls, large screen display engineering, command and control centers, and other occasions that require extremely high clarity due to their superior structural design, good performance indicators, strong stability, and high cost-effectiveness. Recently, the Kodi DVI matrix has been successfully used by the People's Procuratorate of Heilongjiang Province to serve its multifunctional hall renovation project.

The Kodi DVI digital high-definition matrix can transmit and switch DVI high-definition digital video signals at a bitrate of up to 2.25Gbps, with a maximum resolution support of 1920 x 1200, and fully supports all conventional resolutions connected to multifunctional halls; The optional EDID information management function can automatically extract the EDID information of the signal source, ensuring that each output signal can fully read the EDID information, presenting high-quality display effects; Adaptive cable balancing function extends the transmission distance from the signal source equipment to the matrix, solves the strict requirements of DVI signal transmission distance limitations on the placement of multifunctional hall equipment, and also reduces the waste caused by adding extension equipment to a certain extent; The Kodi DVI matrix also has a power-off memory function, ensuring that the number of input and output channels corresponding to the matrix remains unchanged after on-site power outage and re energization, without the need to switch and select again; The modular front and rear plug-in structure was first used by Kodi in China. The power module and control board adopt a front plug-in structure, which can be maintained without changing the wiring. The input and output boards adopt a rear plug-in structure, which only requires replacing or adding modules to complete maintenance and expansion work; The integration of signal interface and signal board solves the process bottlenecks that affect signal quality, such as virtual soldering and missing soldering, and reduces system failure points; Front panel button control, input and output buttons correspond one-to-one, with multiple RS-232, RS-422, RS-485, TCP/IP control interfaces, supporting computer, central control, external panel and other methods for system control simultaneously, making the entire system control more flexible.
