Abstract:
1. An image display system comprising: an image data output device that multiplexes and outputs raster data and compressed moving picture data; and an image display device that is connected to the image data output device through a transmission line and displays an image on the basis of image data output from the image data output device, wherein the image data output device includes: a raster data acquisition unit that acquires the raster data; a compressed moving picture data acquisition unit that acquires the compressed moving picture data; a moving picture display region data generating unit that generates moving picture display region data indicating a display region, of a moving picture based on the compressed moving picture data, within the raster data; a data multiplexer that multiplexes the raster data acquired by the raster data acquisition unit, the compressed moving picture data acquired by the compressed moving picture data acquisition unit, and the moving picture display region data generated by the moving picture display region data generating unit; and a data transmitting unit that transmits multiplexed data through the transmission line, and the image display device includes: a data receiving unit that receives data, which is transmitted from the image data output device, through the transmission line; a data demultiplexer that separates the data received by the data receiving unit into individual data; a moving picture rasterizing unit that performs a rasterizing process for separated compressed moving picture data so as to generate moving picture raster data, wherein the rasterizing process includes decoding the separated compressed moving picture data, the decoding of the separated compressed moving picture data including generation of graphic data corresponding to a region other than the moving picture display region; a display raster data synthesizing unit that synthesizes the moving picture raster data generated by the moving picture rasterizing unit and the raster data so as to generate display raster data; an image forming unit that forms an image on the basis of the generated display raster data; and the compressed moving picture data is not decoded by the image data output device.
