Patent ID: 7613117

Claim:
A motion picture data transmission method performed by a server system for transmitting motion picture data from the server system via a transmission line to a client system, comprising the steps of: checking the content of the transmitted motion picture data; and adjusting the transmission interval in each unit time on the basis of the content data of the motion picture data, wherein the adjusting step comprises: determining when a number of packets corresponding to the motion picture data consecutively transmitted over the transmission line without any delay in transmission between any of the packets reaches a predetermined number of packets; when the number of packets corresponding to the motion picture data consecutively transmitted reaches the predetermined number of packets, providing a wait interval until a next packet corresponding to the motion picture data is to be transmitted of the transmission line; and adjusting the transmission interval between consecutive data blocks of packets by inserting a wait interval between a first data block of packets and a second block of packets adjacent to the first data block of packets wherein the wait interval is determined based in part on detected transmission characteristics of the transmission line.
