Patent ID: 7729311

Claim:
An image data communication system, comprising: an image data distribution device for sequentially distributing, over a transmission resource, a plurality of sets of identical moving picture image data with prescribed time differences; and an image data reception device for receiving, from the transmission resource, moving picture image data that are distributed from said image data distribution device while moving among a plurality of radio areas, wherein when the transmission resource is sufficient to distribute the moving picture image data, said image data reception device, at a time of handover that occurs when moving from a current radio area to another neighboring radio area, receives over a prescribed interval said plurality of sets of identical moving picture image data having prescribed time differences that are distributed from said image data distribution device and selects necessary data from the received moving picture image data to reconstruct one set of moving picture image data, and said image data distribution device, during only said prescribed interval, performs priority control such that said plurality of sets of identical moving picture image data having prescribed time differences are received together in said image data reception device, and wherein when the transmission resource is not sufficient to distribute the moving picture image data, said image data reception device, at the time of handover, receives only one of said plurality of sets of identical moving picture image data, and said image data distribution device performs priority control by discarding ones of said plurality of sets of identical moving picture image data other than said only one.
