Claims15
A recording medium having a data structure for managing playback control of the recording medium, comprising:
- a navigation area storing an information file including a first playback indicator, the first playback indicator identifying a navigation command field for execution at first playback of the recording medium, the navigation area further storing the identified navigation command field, the identified navigation command field including at least one navigation command.
A method of recording a data structure for managing playback control of the recording medium, comprising:
- recording an information file on the recording medium, the information file including a first playback indicator, the first playback indicator identifying a navigation command field for execution at first playback of the recording medium;
- and
- recording the identified navigation command field on the recording medium, the identified navigation command field including at least one navigation command.
A method of reproducing a data structure for managing playback control of the recording medium, comprising:
- reproducing an information file from the recording medium, the information file including a first playback indicator, the first playback indicator identifying a navigation command field for execution at first playback of the recording medium;
- and
- reproducing the identified navigation command field from the recording medium, the identified navigation command field including at least one navigation command.
An apparatus for recording a data structure for managing playback control of the recording medium, comprising:
- a driver for driving an optical recording device to record data on the recording medium;
- a controller for controlling the driver to record an information file on the recording medium, the information file including a first playback indicator, the first playback indicator identifying a navigation command field for execution at first playback of the recording medium;
- and controlling the driver to record the identified navigation command field on the recording medium, the identified navigation command field including at least one navigation command.
An apparatus for reproducing a data structure for managing playback control of the recording medium, comprising:
- a driver for driving an optical reproducing device to reproduce data recorded on the recording medium;
- a controller for controlling the driver to reproduce an information file from the recording medium, the information file including a first playback indicator, the first playback indicator identifying a navigation command field for execution at first playback of the recording medium;
- and to reproduce the identified navigation command field from the recording medium, the identified navigation command field including at least one navigation command.
