Abstract
A video delivery apparatus includes: a division unit to divide video information corresponding to one screen, which is to be delivered to each of multiple display modules constituting a display, into pieces of video information each corresponding to the number of output lines, which is N times (N is an integer of one or greater) a line indicating pixels per one line of the corresponding display module, and output the pieces of video information corresponding to the number of output lines for each of the multiple display modules; and a delivery processor to deliver the video information corresponding to one screen of the display by repetitively delivering, to the multiple display modules, delivery data obtained by multiplexing the pieces of video information corresponding to the number of output lines of the respective multiple display modules, output from the division unit, and control information indicating the target display modules to which the pieces of video information corresponding to the number of output lines are to be delivered respectively. Thus, it is possible to reduce the size of a memory held by a display controller.
