Distributed image control systems have emerged based on the shortcomings of traditional centralized controllers and new market development trends. Distributed image control system is a high-performance and flexible display control solution for large screen splicing walls, based on embedded systems, proprietary real-time image encoding and decoding algorithms, and high-speed Ethernet channels. The SW series network distributed hardware processor is a large screen splicing product independently developed by Century Technology in China. It combines complex high bandwidth network technology, pure hardware lossless decoding, signal intelligent selection and other technologies in the computer field, and can flexibly connect a large number of diverse video sources to the same large number of diverse output devices, achieving functions such as video scaling, cross screen, roaming, etc. This processing system is easy to install and maintain, making it a wizard in the history of the processing system series.

Pure hardware distributed architecture:

The Shangwei SW system adopts a pure hardware distributed architecture, without the risk of operating system infection and crash. The signals are transmitted through network exchange, with simple wiring. Each display unit and signal acquisition endpoint are independent of each other, with unlimited expansion. The signal is transmitted over long distances, with strong stability and easy and fast maintenance. If there are any abnormalities, troubleshooting and restoration to normal can be achieved within 10 minutes.

Lossless decompression • Real time transmission:

The system improves JPEG2000 decompression to achieve a lossless compression ratio of 50% even in extreme cases. This compression method is frame independent compression, which is different from the frame dependent compression method of H.264. SW can achieve real-time signal transmission.
