摘要

An information recording medium includes a file for storing object data consisting of a plurality of packets and a file for storing, as its reproduction control information, (i) correspondence definition information for defining relationship between a plurality of packets and a plurality of partial streams multiplexed on the time axis and (ii) reproduction output group definition information for defining as the reproduction output group a set of partial streams which can be switched among the plurality of partial streams. The partial streams include a plurality of channel streams wherein audio information on plural channels is recorded in one stream. The reproduction output group definition information defines the reproduction output group in such a way that a plurality of channel streams can redundantly belong to it. The reproduction output group to which plural channel streams redundantly belong is added by channel specification information.
