Zusammenfassung:	In order to eliminate timing offset between reproduction devices when a content transmitted from a distribution device is received and reproduced by a plurality of reproduction devices, data (SCR) indicating the elapsed time from the start of the content, generated by counting clock pulses, and data (FCR) indicating a frame number generated by counting the number of frames reproduced by a decoder (54) are transmitted by the distribution device, and a clock generation unit (103) in each reproduction device is controlled so that data (STC) indicating the elapsed time and data (FTC) indicating the frame number, which are generated in the same manner by each reproduction device, match the transmitted data (SCR, FCR). Synchronization between reproduction devices can thereby be established even when, in a state in which a content is being reproduced by one reproduction device, another reproduction device subsequently connects to the distribution device.
