Abstract
A data management method which causes equipment such as a camera integral-type recording and reproducing apparatus to manage an external reference type container file and an audiovisual stream file by setting an attribution of all the external reference type container files recorded in a disk to an invisible state. Therefore, reproduction of the container file can be performed in the main body of the equipment, and only the audiovisual stream file can be reproduced when the disk is reproduced in, e.g. a personal computer.
Claims16
A reproducing method for reproducing data recorded on a recording medium attached to a reproducing apparatus, comprising:
- a recording step of generating a plurality of directories including at least first and second directories different from each other on the recording medium, recording a video stream file in the first directory on the recording medium, and recording container files one of which supports the video stream file, in the second directory on the recording medium,
- wherein one of the container files has a data structure of an external reference type for reproducing the video stream file recorded in the first directory and includes link information for providing a link to the video stream file;
- a file attribution setting step of setting file attributions of all of the container files recorded in said recording step into an invisible state so as to prohibit the container files from being displayed;
- a recognition step of recognizing records recorded on the recording medium in said recording step, in response to start of a reproduction operation of the recording medium;
- a display control step of reproducing one or more of the container files from the second directory on the recording medium recognized in said recognition step to produce one or more reproduced container files, and controlling display of the one or more reproduced container files such that the one or more reproduced container files are forcibly displayed in a form of a file list on a display device installed in the reproducing apparatus in the case that the one or more reproduced container files are displayed only on the display device, even if the file attribution of each of the one or more reproduced container files has been set into the invisible state;
- and
- a reproduction step of selecting one of the container files displayed in the form of the file list in said display step and reproducing the video stream file linked to the selected container file via the link information included therein, from the first directory on the recording medium in accordance with the link information included in the selected container file.

A reproducing system for reproducing data recorded on a recording medium attached to a reproducing apparatus, comprising:
- a recorder which generates a plurality of directories including at least first and second directories different from each other on a recording medium, records a video stream file in the first directory on the recording medium, and records container files one of which supports the video stream file, in the second directory on the recording medium, wherein a predetermined container file has a data structure of an external reference type for reproducing the video stream file recorded in the first directory and includes link information for providing a link to the video stream file;
- a file attribution setting unit which sets file attributions of all of the container files recorded in said recorder into an invisible state so as to prohibit the container files from being displayed;
- a recognizer which recognizes records recorded on the recording medium by said recorder, in response to start of a reproduction operation of the recording medium;
- a display controller which reproduces one or more of the container files from the second directory on the recording medium recognized by said recognizer to produce one or more reproduced container files and controls display of the one or more reproduced container files such that the one or more reproduced container files are forcibly displayed in a form of a file list on a display device installed in the reproducing apparatus in the case that the one or more reproduced container files are displayed only on the display device, even if the file attribution of each of the one or more reproduced container files has been set into the invisible state;
- and
- a reproducer which selects one of the container files displayed in the form of the file list by said display controller and reproduces the video stream file linked to the selected container file via the link information included therein, from the first directory on the recording medium in accordance with the link information included in the selected container file.

A reproducing apparatus for reproducing data recorded on a recording medium attachable to said reproducing apparatus, comprising:
- a recorder which generates a plurality of directories including at least first and second directories different from each other on a recording medium, records a video stream file in the first directory on the recording medium, and records container files one of which supports the video stream file, in the second directory on the recording medium, wherein one of the container files has a data structure of an external reference type for reproducing the video stream file recorded in the first directory and includes link information for providing a link to the video stream file;
- a file attribution setting unit which sets file attributions of all of the container files recorded in said recorder into an invisible state so as to prohibit the container files from being displayed;
- a recognizer which recognizes records recorded on the recording medium by said recorder, in response to start of a reproduction operation of the recording medium;
- a display controller which reproduces one or more of the container files from the second directory on the recording medium recognized by said recognizer to produce one or more reproduced container files and controls display of the one or more reproduced container files such that the one or more reproduced container files are forcibly displayed in a form of a file list on a display device installed in said reproducing apparatus in the case that the one or more reproduced container files are displayed only on the display device, even if the file attribution of each of the one or more reproduced container files has been set into the invisible state;
- and
- a reproducer which selects one of the container files displayed in the form of the file list by said display controller and reproduces the video stream file linked to the selected container file via the link information included therein, from the first directory on the recording medium in accordance with the link information included in the selected container file.

A recording apparatus for recording data on a recording medium which is attachable to a reproducing apparatus, comprising:
- a recorder which generates a plurality of directories including at least first and second directories different from each other on a recording medium, records a video stream file in the first directory on the recording medium, and records container files one of which supports the video stream file, in the second directory on the recording medium, wherein one of the container files has a data structure of an external reference type for reproducing the video stream file recorded in the first directory and includes link information for providing a link to the video stream file;
- a file attribution setting unit which sets file attributions of all of the container files recorded in said recorder into an invisible state so as to prohibit the container files from being displayed;
