Abstract: A multi-screen signal processing device includes a main graphics processor and a plurality of sub-graphics processors. The main graphics processor is electrically connected to the plurality of sub-graphics processors respectively. The main graphics processor is used for receiving an external image data, and capable of decoding the external image data and outputting a frame data. Each sub-graphics processor respectively captures a part of the frame data synchronously and outputs a broadcasting signal. The multi-screen signal processing device may be connected to multiple screens to play multiple images at the same time. Moreover, the decoding step using a single graphics processor enables easy synchronization of frames displayed on different screens and saves energy consumed by repeating the decoding step.

Abstract: A network media processing device includes a network connection module and a graphics processor. The network connection module is electrically connected to the graphics processor directly. The network connection module is used for connecting to a local area network (LAN). Through the LAN, a host may transmit or broadcast digital image data to the network connection module. The network media processing device can receive media data transmitted by the network with a very simple hardware construction. Therefore, the use convenience can be greatly improved when media data is transmitted using a LAN.
