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.
