The AV matrix and VGA/RGB matrix produced by Dalian Kedi (KD) in 2007, which support hot swapping and expandable plugins, have attracted the attention of a large number of integrators and have been widely used in Jinan Radio and Television, Henan Provincial Government, Beijing Huairou District Government, Fujian Security Department, national security agencies, and public security systems. Recently, the Peking University Library has also expanded the 32x32 video and audio matrix purchased last year directly to a 64x64 video and audio matrix.

"Support for hot swapping and expandable plug-in board" refers to the design method of "modular design, plug-in board structure, and hot swappable". During expansion, the entire matrix is expanded by simply inserting a video and audio switching board without power supply. The entire process only takes a few minutes, and the original signal switching is not affected. However, most brand matrices can only be expanded by repurchasing and replacing equipment as a whole, which incurs extremely high costs and requires all signal cables to be reinserted and all equipment to be reinstalled and debugged. During the replacement period, the user's original signal cannot be switched, delaying normal use, which is both time-consuming and labor-intensive.

The so-called "modular design, plug-in structure, and hot swappable" is currently an advanced matrix design structure internationally. The Kodi (KD) matrix system adopts this advanced structure, which enables all circuit boards to support hot swapping, bringing great convenience to system maintenance and expansion. For equipment that needs to be expanded, only the expansion interface and slide need to be reserved, and the corresponding switching board can be inserted during expansion. The original signal switching will not be affected, greatly reducing the costs of integrators and users. A 6U matrix chassis of Kodi (KD) can be expanded from a 16x16 matrix to a 64x64 matrix, a 12U chassis can be expanded to 128x128, and if needed, the Kodi (KD) matrix can be expanded to 512x512 and customized according to user requirements.
