<p>Disclosed are a method, device and system for synthesizing a multi-screen video. The method comprises: a video processing field programmable gate array (FPGA) receiving, through a high-speed serial bus, multiple videos and respective corresponding addresses sent by a decoding module, the addresses of the videos being determined by the decoding module according to a multi-screen arrangement requirement; zooming the multiple received videos, so that the size of each video is the same as that of a corresponding screen of multiple screens; buffering the zoomed videos, and modifying the address corresponding to each of the buffered videos; storing each of the zoomed videos in a corresponding memory space according to the modified address. The present invention can conserve system resources, and improve the data transmission speed and image quality.</p> |
