Patent ID: 7777692

Claim:
A multi-screen video reproducing system, comprising: a network; a plurality of display devices, each of the plurality of display devices displaying a partial image of an image; a plurality of rendering units connected to the network, each of the plurality of rendering units outputting partial video data corresponding to the partial image allocated to each of the plurality of rendering units to a corresponding display device of the plurality of display devices; and a video distribution server connected to the network to distribute same video data representing the image to each of the plurality of rendering units and to distribute timing information, to output synchronized video data from the plurality of rendering units to the corresponding display devices, to the plurality of rendering units through a simultaneous broadcast communication, the timing information being distributed at a predetermined timing after the distribution of the same video data, the video distribution server including a video data generating section to generate the same video data to be distributed to the plurality of rendering units: a timing information generating section to generate the timing information; and a transmitting section to distribute to the plurality of rendering units the same video data generated by the video data generating section or the timing information generated by the timing information generating section, and each of the rendering units including a receiving section to receive the same video data or the timing information distributed by the transmitting section; a frame buffer to expand the same video data received by the receiving section; an output control section to control the frame buffer based on the timing information received by the receiving section; and an output section to output the partial video data expanded by the frame buffer to the corresponding display device.
