摘要

In the data structure for managing reproduction of data streams recorded on the recording medium, a playlist including a streams table, a playitem and a sub-playitem is provided. The playitem includes information for managing reproduction of a main data stream of data packets, and the sub-playitem includes information for managing reproduction of at least one supplemental data stream of data packets. The streams table provides a list of packet identifiers in the data packets of the main and supplemental data streams. A supplementary data stream might be downloaded and reproduced with the main data stream.
