ABSTRACT:
A broadcast system composed of a first broadcast apparatus and a second broadcast apparatus. The first broadcast apparatus broadcasts a broadcast program composed of contents stream data and attachment data, and provides the second broadcast apparatus with the broadcast program. The attachment data contains information that indicates timing with which the attachment data is to be reproduced in synchronization with the contents stream data. The image sync information contains PCRs generated by the PCR generating apparatus of the first broadcast apparatus based on the standard time for the first broadcast apparatus. The image sync information replacing apparatus of the second broadcast apparatus replaces the PCRs with other PCRs which are newly generated based on the standard time for the second broadcast apparatus so that it can correctly reproduce the attachment data in synchronization with the encoded contents stream data.
