(57) [Summary] [PROBLEMS] To collectively record a plurality of programs and the like transmitted by an MPEG2 transport stream, multiplex-record them on an optical disk or the like, and relatively easily reproduce a desired one of them. And In particular, it is possible to edit recorded data by simple processing. SOLUTION: In an information recording medium, an entire stream including a plurality of partial streams each composed of content information is multiplex-recorded in packet units. The information recording medium includes a file for storing object data composed of a plurality of packets each storing a fragment of content information, and further includes information defining a reproduction sequence of the object data, and a plurality of packets corresponding to a recording order in multiplex recording. And a file for storing information indicating a discontinuity state of the serial number caused by a packet loss at the time of editing for the serial number. |
