Abstract

A video contents recording apparatus and a method of managing a data storage medium include: a data storage medium in which a plurality of contents are recorded; and a controller displaying a list of contents to be deleted generated from the contents recorded in the data storage medium to a user via a display unit according to a predetermined delete priority and deleting contents selected by the user from the data storage medium with reference to the list. According to an embodiment of the present invention, a recording space of a data storage medium having limited data storage capacity may be efficiently managed by automatically deleting contents stored in the data storage medium according to a predetermined priority selected by a user or by providing a delete list for referring to when the user determines contents to be deleted.

Claims

1. A method of managing a data storage medium included in a video contents recording and/or reproducing apparatus, the method comprising:

displaying a list of contents to be deleted generated from a plurality of contents recorded in the data storage medium to a user via a display unit according to a predetermined delete priority; and

2. The method of claim 1, wherein the delete priority is set by a user.

3. The method of claim 2, wherein the delete priority is determined by the user before recording the contents in the data storage medium by determining as a criterion for priority at least one of:

whether the contents recorded in the data storage medium have been viewed;

whether a storing duration of the contents has expired;

a level of importance of the stored contents;

a remaining storage duration;

a stored duration;

a number of reproduction times;

a size of the contents;

or a combination thereof.

4. The method of claim 1, wherein the deleting of the contents further comprises:

generating a summary of the contents to be deleted and storing the summary of the contents to be deleted in the data storage medium.

5. The method of claim 4, wherein the storing of the summary of the content to be deleted is performed according to a predetermined preference of the user.

6. A method of managing a data storage medium included in a video contents recording apparatus, the method comprising:

determining contents to be deleted with reference to a list of contents to be deleted generated from a plurality of contents recorded in the data storage medium according to a predetermined delete priority; and

deleting the contents to be deleted from the data storage medium.

7. The method of claim 6, wherein the delete priority is determined by the user before recording the contents in the data storage medium by determining as a criterion for priority at least one of:

whether the contents recorded in the data storage medium have been viewed;

whether a storing duration of the contents has expired;

a level of importance of the stored contents;

a remaining storage duration;

a stored duration;

a number of reproduction times

a size of the contents;

or

a combination thereof.

8. The method of claim 6, wherein the deleting of the contents further comprises:

generating a summary of the contents to be deleted and storing the summary of the contents to be deleted in the data storage medium.

9. A video contents recording and/or reproducing apparatus comprising:

a data storage medium on which a plurality of contents are recorded; and

a controller displaying a list of contents to be deleted which is generated from the contents recorded on the data storage medium to a user via a display unit according to a predetermined delete priority and deleting contents selected by the user from the data storage medium with reference to the list.

10. The apparatus of claim 9, wherein the delete priority is set by a user.

11. The apparatus of claim 10, wherein the delete priority is determined by the user before recording the contents in the data storage medium by determining as a criterion of priority at least one of:

whether the contents recorded in the data storage medium have been viewed;

whether a storing duration of the contents has expired;

a level of importance of the stored contents;

a remaining storage duration;

a stored duration;

a number of reproduction times;

a size of the contents;

or

a combination thereof.

12. The apparatus of claim 9, wherein the controller generates a summary of the contents to be deleted and stores the summary of the contents to be deleted in the data storage medium.

13. The apparatus of claim 12, wherein the controller generates a summary of the contents to be deleted and stores the summary of the contents to be deleted in the data storage medium in response to a command to generate the summary input from the user.

14. A video contents recording and/or reproducing apparatus, comprising:

a data storage medium on which a plurality of contents are recorded; and

a controller determining contents to be deleted with reference to a list of contents to be deleted and which is generated from the contents recorded in the data storage medium according to a predetermined delete priority and deleting the contents to be deleted from the data storage medium.

15. The apparatus of claim 14, wherein the delete priority is determined by the user before recording the contents in the data storage medium by determining as a criterion of priority at least one of:

whether the contents recorded in the data storage medium have been viewed;

whether a storing duration of the contents has expired;

a level of importance of the stored contents;

a remaining storage duration;

a stored duration;

a number of reproduction times;

a size of the contents;

or

a combination thereof.

16. The apparatus of claim 14, wherein the controller generates a summary of the contents to be deleted and stores the summary of the contents to be deleted in the data storage medium.

17. A computer readable medium having recorded thereon a computer readable program to perform a method of deleting recorded contents which is performed by a computer, the method comprising:
