Abstract

A set age of a user is updated on the basis of information of the birth date of the user and date information updated with time. Taste information of the user is learned on the basis of operation history information of the user and contents related information corresponding to the operation. Contents extraction conditions are reset in accordance with the taste information of the user and the updated set age, and contents which can be an object to be watched by the user are extracted from a plurality of contents depending on the reset extraction conditions.

Claims

1. A contents extraction method comprising the step of:

updating a set age of a user on the basis of information related to reference time at which the set age of the user is updated and time information which is updated with time;

resetting extraction conditions of contents such that at least one of the contents extracted before the updating is excluded in accordance with taste information of the user and the updated set age; and

extracting contents which can be an object to be watched by the user from a plurality of contents depending on the extraction conditions.

2. A contents extraction method comprising the step of:

updating a set age of a user on the basis of information related to reference time at which the set age of the user is updated and time information which is updated with time;

resetting extraction conditions of contents in accordance with taste information of the user and the updated set age; and

extracting contents which can be an object to be watched by the user from a plurality of contents depending on the extraction conditions.

3. The contents extraction method according to claim 2, wherein under the extraction conditions, at least one of the contents extracted before the updating is excluded and/or at least one of contents which are not an object to be extracted before the updating is added to extract contents.

4. The contents extraction method according to claim 3, wherein under the extraction conditions, candidates of contents to be excluded are selected in accordance with the updated set age, and contents to be excluded are determined in the candidates in accordance with the taste information of the user.

5. The contents extraction method according to claim 3, wherein, of candidates of the contents to be excluded, contents which are not matched with the taste of the user are excluded.

6. The contents extraction method according to claim 2, comprising the step of further restricting contents to be extracted from the plurality of extracted contents on the basis of contents related information associated with the contents.

7. A contents information display method wherein a display state of information related to contents extracted depending on the contents extraction method according to claim 2 can be updated in accordance with updating of a set age.

8. A contents information display method wherein, in a state in which the visibility of information related to contents extracted by the contents extraction method according to claim 2 is higher than the visibility of information related to unextracted contents, information related to these contents is displayed.

9. A contents extraction apparatus comprising:

an age-increase process unit which updates a set age of a user on the basis of information related to reference time at which the set age of the user is updated and time information which is updated with time;

a contents related information holding unit which holds contents related information associated with the contents;

a user taste information learning unit which learns taste information of the user on the basis of operation history information of the user and contents related information corresponding to the operation;

a condition resetting unit which resets extraction conditions of contents such that at least one of the contents extracted before the updating is excluded in accordance with taste information of the user and the updated set age; and

a contents extraction unit which extracts contents which can be an object to be watched by the user from a plurality of contents depending on the reset extraction conditions.

10. A contents extraction apparatus comprising:

an age-increase process unit which updates a set age of a user on the basis of information related to reference time at which the set age of the user is updated and time information which is updated with time;

a contents related information holding unit which holds contents related information associated with the contents;

a user taste information learning unit which learns taste information of the user on the basis of operation history information of the user and contents related information corresponding to the operation;

a condition resetting unit which resets extraction conditions of contents in accordance with taste information of the user and the updated set age; and

a contents extraction unit which extracts contents which can be an object to be watched by the user from a plurality of contents depending on the reset extraction conditions.

11. The contents extraction apparatus according to claim 10, wherein under the extraction conditions, at least one of the contents extracted before the updating is excluded and/or at least one of contents which are not an object to be extracted before the updating is added to extract contents.

12. The contents extraction apparatus according to claim 11, wherein under the extraction conditions, candidates of contents to be excluded are selected in accordance with the updated set age, and contents to be excluded are determined in the candidates in accordance with the taste information of the user.

13. The contents extraction apparatus according to claim 11, wherein, of candidates of the contents to be excluded, contents which are not matched with the taste of the user are excluded.

14. The contents extraction apparatus according to claim 10, further comprising a narrow-down process unit which further restricts contents to be extracted from the plurality of extracted contents on the basis of contents related information associated with the contents.

15. A display apparatus comprising:

the contents extraction apparatus according to claim 10;

a display unit which displays information related to the contents; and

a display method change unit which updates a display state of information related to the extracted contents depending on updating of a set age.

16. A display apparatus comprising:

the contents extraction apparatus according to claim 10;

a display unit which displays information related to the contents; and

a display method change unit which changes a display method of information related to the contents such that the visibility of information related to extracted contents is higher than the visibility of information related to unextracted contents.
