Claim:
A non-transitory computer-readable information recording medium or a non-transitory computer-associated-machine-readable information recording medium configured to have data recorded thereon by a computer-associated recording apparatus and/or data reproduced therefrom by a computer-associated reproducing apparatus, the data including management information and digital stream information, wherein the digital stream information includes a first stream corresponding to an MPEG transport stream or a second stream obtained via an IEEE 1394 interface corresponding to a non-MPEG transport stream, the first stream comprising one or more elementary streams carried by data packets, and the management information comprises type information indicating whether the digital stream information includes an MPEG transport stream or not the MPEG transport stream, number information describing a number of the elementary streams defined in a portion of the digital stream information, time map information showing a relation between a presentation time and a position of one of the elementary streams, and packet ID information indicating a packet ID of the data packets, which carry a target elementary stream relating to the time map information, when a content of the type information indicates the MPEG transport stream, the first stream is configured to be recorded with a first data size being not less than a packet size of the MPEG transport stream, and when another content of the type information indicates the non-MPEG transport stream, the second stream is configured to be recorded with a second data size being not less than the MPEG transport stream packet size, the second data size being different from the first data size.
