Abstract

In DVRVolume( ), there is stated the information pertinent to the totality of the information recorded in a disc. The information recorded in the disc can be confirmed on the basis of this description. In TableOfPlayList( ), there is stated the information usable in reproducing the information recorded in the disc. Using this description, the desired information can be retrieved extremely readily. So, the information recorded in the disc or desired information can be confirmed extremely readily.

Claims

1. An information processing apparatus comprising:

generating means for generating one or more PlayList files specifying a sequence of reproducing information recorded on a recording medium, and generating a management information file supervising said one or more PlayList files; and

recording means for recording said one or more PlayList files and said management information file on said recording medium;

said management information file containing a resume PlayList file name that indicates a name of a particular PlayList file whose playback has been terminated; and

said particular PlayList file containing temporal information on a time point of the termination of the playback of the particular PlayList file, wherein said recording means records said temporal information on said recording medium after the time point of the termination.

2. An information processing method comprising:

a step of generating one or more PlayList files specifying a sequence of reproducing information recorded on a recording medium, and generating a management information file supervising said one or more PlayList files; and

a step of recording said one or more PlayList files and said management information file on said recording medium;

said management information file containing a resume PlayList file name that indicates a name of a particular PlayList file whose playback has been terminated; and

said particular PlayList file containing temporal information on a time point of the termination of the playback of the particular PlayList file, wherein said recording step records said temporal information on said recording medium after the time point of the termination.

3. A recording medium having recorded thereon a computer-readable program that when executed by a processor perform steps comprising:

a generating step of generating by the processor one or more PlayList files specifying a sequence of reproducing information recorded on a recording medium, and generating a management information file supervising said one or more PlayList files; and

a recording step of recording said one more PlayList files and said management information file on said recording medium;

said management information file containing a resume PlayList file name that indicates a name of a particular PlayList file whose playback has been terminated; and

said particular PlayList file containing temporal information on a time point of the termination of the playback of the particular PlayList file, wherein said recording step records said temporal information on said recording medium after the time point of the termination.

4. An information processing apparatus comprising:

a playback mechanism configured to reproduce main information from a recording medium having recorded thereon one or more PlayList files specifying a playback sequence of said main information and a management information file supervising said one or more PlayList files; and

control means for controlling a playback of the main information on said recording medium based on said management information file containing a resume PlayList file name that indicates a name of a particular PlayList file whose playback has been terminated, said particular PlayList file containing temporal information on said time point of the termination of the playback of the particular PlayList file, wherein the temporal information on the time point of the termination was recorded on the recording medium after the time point of the termination.

5. An information processing method comprising:

reproducing a main information from a recording medium having recorded thereon one or more PlayList files specifying a playback sequence of said main information and a management information file supervising said one or more PlayList files; and

a control step of controlling a playback of the main information on said recording medium based on said management information file containing a resume PlayList file name that indicates a name of a particular PlayList file whose playback has been terminated, said particular PlayList file containing temporal information on a time point of the termination of the playback of the particular PlayList file, wherein the temporal information on the time point of the termination was recorded on the recording medium after the time point of the termination.

6. A recording medium having recorded thereon a computer-readable program that when executed by a processor performs a method comprising:

reproducing a main information from a recording medium having recorded thereon one or more PlayList files specifying a playback sequence of said main information and a management information file supervising said one or more PlayList files; and

a control step of controlling a playback of the main information on said recording medium based on said management information file containing a resume PlayList file name that indicates a name of a particular PlayList file whose playback has been terminated, said particular PlayList file containing temporal information on a time point of the termination of the playback of the particular PlayList file, wherein the temporal information on the time point of the termination was recorded on the recording medium after the time point of the termination.
