The DS-C30S video wall controller is a new-generation pure hardware image processing device based on FPGA. Compared with the traditional controller, the device has a brand-new system structure and adopts data dual exchange technology to support large-capacity data transmission and processing. With high image processing performance, the device supports the access and real-time processing of multi-channel high definition and ultra-high definition signals. Adopting the structure of main control board plus input and output board, which can be configured as required, the device supports multi-screen management. This product is mainly used in large-screen splicing control system and considered the core control device of the system.
