After reproduction of AV data is interrupted, the story before the interruption can easily be grasped and accompanying information associated with a character is displayed as is necessary. A main file (101) of the AV data recorded on an AV data recording medium (10) is divided into one or more chapters (101a, 101b, . . . ) and recorded. A digest of each chapter is recorded as digest data (102a, 102b, . . . ) and recorded in a digest file (102), which is correlated to each chapter of the main file (101) and recorded on the same or different AV data recording medium (10) as or from the main file (101). When reproducing the interrupted main file (101), the digest file (102) corresponding to the respective chapters before the interruption is reproduced before the main file (101) interrupted is reproduced. Moreover, instead of the digest file (102), it is possible to record accompanying information on a character such as a person coming on the scene and select the type of accompanying information to be reproduced.

An AV data recording method for recording AV data onto an arbitrary recording medium, wherein a first AV data are divided into one or more sections to be recorded onto the recording medium, wherein a second AV data having information associated with each of the sections of the first AV data recorded on the recording medium are recorded onto the same recording medium as the recording medium recording the first AV data or a different recording medium, correspondingly to each of the sections of the first AV data, wherein section identification information is included as the second AV data recorded correspondingly to each of the sections of the first AV data, which can identify each section starting from the beginning section of the first AV data to a section immediately before the section made correspond to the second AV data, and wherein when reproduction of the second AV data is instructed, based on the section identification information, the reproduction is started from the second AV data corresponding to the beginning section to reproduce each piece of the second AV data corresponding to each section until the section immediately before, which is specified in the section identification information as a section indicating unreproduced beginning of the first AV data.

An AV data reproduction method for reproducing AV data recorded on an arbitrary recording medium, which switches and reproduces either a first AV data divided into one or more sections and recorded onto the recording medium or a second AV data having information associated with each of the sections of the first AV data recorded onto the same recording medium as the recording medium recording the first AV data or a different recording medium, correspondingly to each of the sections of the first AV data, wherein section identification information is included as the second AV data recorded correspondingly to each of the sections of the first AV data, which can identify each section starting from the beginning section of the first AV data to a section immediately before the section made correspond to the second AV data, and wherein when reproduction of the second AV data is instructed, based on the section identification information, the reproduction is started from the second AV data corresponding to the beginning section to reproduce each piece of the second AV data corresponding to each section until the section immediately before, which is specified in the section identification information as a section indicating unreproduced beginning of the first AV data.
