This prior art search report presents the mappings of the various elements of claim 1 of U.S. Patent No. 8,909,809 (‘809 Patent), titled “Delivery system, delivery method, server device, program, and client device”, from assignee NEC Corporation, published on 9 December 2014.
This patent discloses a delivery system able to adjust the bit rate of content data transmitted from a server to a client device based on the stored content data that can be reproduced (i.e., “remaining reproduction time”). The server device is able to transmit the content data in one of a plurality of bit rates. The client device receives and stores a portion thereof and reproduces content based on said stored portion. The delivery system acquires the “remaining reproduction time” based on a portion of the stored data and calculates, according to a predetermined procedure, a correction amount for correcting the bit rate based on it. The delivery system changes the bit rate based on the calculated correction amount, and when the bit rate is within a predetermined range, the delivery system calculates a correction amount having a smaller magnitude than a magnitude of the correction amount calculated according to the procedure.
