Document Type and Number:
Japanese Patent JP5494495
Kind Code:
B2
Abstract:
A server device is configured to be able to transmit content data having one of a plurality of bit rates. While receiving the content data, a client device stores a received portion thereof and reproduces content based on the stored data. A delivery system acquires a period of time during which content can be reproduced (remaining reproduction time) based on a portion of the stored data that has not been reproduced. The delivery system calculates, according to a predetermined procedure, a correction amount for correcting the bit rate based on the remaining reproduction time, and changes the bit rate based on the calculated correction amount. 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.
