## Abstract

In order to provide a recording and reproducing device that allows a user to select and manage arbitrary play lists, a unit of management for managing all registered play list information and an upper management hierarchical level are added. The unit of management is adapted to be handled on the same level with unified information that indicates a reproduction range of all AV data. User-defined unified information is adapted to be handled on the added management hierarchical level. The user-defined unified information is formed to allow arbitrary reproduction ranges contained on a lower hierarchical level to be registered.

## Claims

### Claim 1

A recording method including a recording step for recording on a recording medium AV data and management information used to manage the AV data,
the management information comprising:
program information paired with the AV data;
original unified information for managing history of the program information;
user-defined program information which is arbitrarily defined by a user to manage reproduction positions of the AV data;
play list information for managing a reproduction sequence of the user-defined program information or the program information paired with the AV data; and
play list unified information for managing history of the play list information,
wherein as for the management information,
the original unified information and the play list unified information are placed on a first management hierarchical level,
the play list information is placed on a second management hierarchical level, and
the program information paired with the AV data and the user-defined program information are placed on a third management hierarchical level.

### Claim 2

A recording method including a recording step for recording on a recording medium AV data and management information used to manage the AV data,
the management information comprising:
program information paired with the AV data;
original unified information for managing history of the program information;
user-defined program information which is arbitrarily defined by a user to manage reproduction positions of the AV data;
play list information for managing a reproduction sequence of the user-defined program information or the program information paired with the AV data; and
play list unified information for managing history of the play list information,
wherein
the original unified information, the play list unified information, and the user-defined unified information are placed on a first management hierarchical level,
the play list information is placed on a second management hierarchical level,
the program information paired with the AV data and the user-defined program information are placed on a third management hierarchical level, and
AV data of recorded programs are placed on a lowest management hierarchical level.

### Claim 3

A recording and reproducing device comprising:
a receiving circuit for receiving input AV data;
a recording unit signal processing circuit for recording AV data received by the receiving circuit on a recording medium;
a reproducing unit signal processing circuit for reproducing the AV data from the recording medium;
output unit for outputting AV data read out from the reproducing unit signal processing circuit;
user interface unit manipulated by a user; and
control unit for controlling each of the circuits in response to input from the user interface means,
wherein at time of recording, the AV data and management information for managing the AV data are recorded by the control unit and the recording unit signal processing circuit, and
wherein the management information comprises:
program information paired with the AV data and original unified information for managing history of the program information
user-defined program information which is arbitrarily defined by the user to manage reproduction positions of the AV data;
play list information for managing a reproduction sequence of the user-defined program information or the original program information; and
play list unified information for managing history of the play list information,
wherein as for the management information,
the original unified information and the play list unified information are placed on a first management hierarchical level,
the play list information is placed on a second management hierarchical level, and
the program information paired with the AV data and the user-defined program information are placed on a third management hierarchical level.

### Claim 4

A recording and reproducing device comprising:
a receiving circuit for receiving input AV data;
a recording unit signal processing circuit for recording AV data received by the receiving circuit on a recording medium;
a reproducing unit signal processing circuit for reproducing the AV data from the recording medium;
output unit for outputting AV data read out from the reproducing unit signal processing circuit
user interface unit manipulated by a user; and
control unit for controlling each of the circuits in response to input from the user interface means,
wherein at time of recording, the AV data and management information for managing the AV data are recorded by the control unit and the recording unit signal processing circuit, and
wherein the management information comprises:
program information paired with the AV data and original unified information for managing history of the program information;
user-defined program information which is arbitrarily defined by the user to manage reproduction positions of the AV data;
play list information for managing a reproduction sequence of the user-defined program information or the original program information; and
play list unified information for managing history of the play list information,
wherein
the original unified information, the play list unified information and the user-defined unified information are placed on a first management hierarchical level,
the play list information is placed on a second management hierarchical level, and
the program information paired with the AV data and the user-defined program information are placed on a third management hierarchical level.
