Information recording apparatus and method for the same

A recording method comprising:

• receiving, via a receiver unit of a recording apparatus, a digital stream, which is a multiplex of a video stream and an audio stream;
• receiving a first entry point representing a starting point of a playback of the digital stream, the first entry point being defined by a user;
• automatically producing, during a monitoring of the digital stream, a second sentry point representing a change point at which an attribute of the digital stream changes;
• generating management information;
• and
• recording the generated management information and the digital stream onto a recording medium,
• wherein the management information includes:
• playback path information representing a playback path of the digital stream;
• and
• stream management information for managing the digital stream, the stream management information being different from the playback path information,
• wherein the first entry point contains first type information,
• wherein the second entry point contains second type information, and
• wherein the first type information includes a different number of pieces of information than the second type information.

A non-transitory computer-readable recording medium having data recorded thereon by a recording apparatus, wherein the data comprises:

• a digital stream, which is a multiplex of a video stream and an audio stream;
• management information;
• a first entry point;
• and
• a second entry point,
• wherein the management information includes:
• playback path information representing a playback path of the digital stream;
• and
• stream management information for managing the digital stream, the stream management information being different from the playback path information,
• wherein the first entry point contains first type information, the first entry point representing a starting point of a playback of the digital stream, and the first entry point being defined by the user,
• wherein the second entry point contains second type information, the second entry point representing a change point at which an attribute of the digital stream changes, and the second entry point being automatically produced during a monitoring of the digital stream, and
• wherein the first type information includes a different number of pieces of information than the second type information.

A reproducing apparatus comprising:

• a reading device operable to read a digital stream, management information, a first entry point and a second entry point from a recording medium, the digital stream being a multiplex of a video stream and an audio stream;
• and
• a playback device operable to playback the digital stream in accordance with the management information,
• wherein the management information includes:
• playback path information representing a playback path of the digital stream;
• and
• stream management information for managing the digital stream, the stream management information being different from the playback path information,
• wherein the first entry point contains first type information, the first entry point representing a starting point of a playback of the digital stream, and the first entry point being defined by the user,
• wherein the second entry point contains second type information, the second entry point representing a change point at which an attribute of the digital stream changes, and the second entry point being automatically produced by a recording apparatus during a monitoring of the digital stream by the recording apparatus, and
• wherein the first type information includes a different number of pieces of information than the second type information.

A reproducing method comprising:

• reading, via a reading unit of a reproducing apparatus, a digital stream, management information, a first entry point and a second entry point from a recording medium, the digital stream being a multiplex of a video stream and an audio stream;
• and
• playing back the digital stream in accordance with the management information,
• wherein the management information includes:
• playback path information representing a playback path of the digital stream;
• and
• stream management information for managing the digital stream, the stream management information being different from the playback path information,
• wherein the first entry point contains first type information, the first entry point representing a starting point of a playback of the digital stream, and the first entry point being defined by the user,
• wherein the second entry point contains second type information, the second entry point representing a change point at which an attribute of the digital stream changes, and the second entry point being automatically produced by a recording apparatus during a monitoring of the digital stream by the recording apparatus, and
• wherein the first type information includes a different number of pieces of information than the second type information.
