Title: GENERATION DEVICE, REPRODUCTION DEVICE, DATA STRUCTURE, GENERATION METHOD, REPRODUCTION METHOD, CONTROL PROGRAM, AND RECORDING MEDIUM
Abstract:
A transmitter (1) is equipped with: a CI update determination unit (15) for identifying a media unit with updated composition information (CI) among multiple media units; and a header generation unit (14) for generating a transfer packet by adding a header, which includes a flag that indicates an update of the composition information, to the media unit identified by the CI update determination unit (15). Consequently, the possibility of erroneous reproduction by a reproduction device without reflecting the update on information to be reproduced is reduced.
