Abstract

An information navigation apparatus monitors a user'"'"'s preferential tendencies among huge amounts of digital content using as objective a criterion as possible, and displays content information that would facilitate the user'"'"'s content selection based on the monitored data. The apparatus is capable of accommodating the user'"'"'s modification of his or her preferential tendencies on the spot. The information navigation apparatus comprises a content selection history memory unit for storing a user'"'"'s content selection history, a content information database for storing content information about digital content, a preference analysis unit for analyzing the user'"'"'s preferences based on said content information and said user'"'"'s content selection history, and display means for displaying the result of analysis of the user'"'"'s preferences by said preference analysis unit.

Claims

1. An information navigation apparatus comprising:

a content information database for storing content information about digital content;

a content selection history memory unit for storing a user'"'"'s content selection history; and

a preference analysis unit for analyzing the user'"'"'s preferences based on said content information and said user'"'"'s content selection history.

2. The information navigation apparatus according to claim 1, further comprising display means for displaying the result of analysis of the user'"'"'s preferences by said preference analysis unit.

3. The information navigation apparatus according to claim 1, wherein said content information includes classification information about each item of digital content.

4. The information navigation apparatus according to claim 3, wherein said content information further includes information about the contents of each digital content item.

5. The information navigation apparatus according to claim 4, wherein said information about the contents of each digital content item includes at least one of the items of information about the producer, cast, target age group, original writer, distributor, and country of origin.

6. The information navigation apparatus according to claim 4, wherein said display means displays the result of analysis of the user'"'"'s preferences using the classification information about each digital content item and at least one of the items of information about the contents.

7. The information navigation apparatus according to claim 1, wherein said display means further displays available content items that match the user'"'"'s preferences in accordance with the result of analysis of the user'"'"'s preferences by said preference analysis unit.

8. The information navigation apparatus according to claim 1, further comprising modification means for allowing the user to modify the result of analysis of the user'"'"'s preferences being displayed by said display means.

9. The information navigation apparatus according to claim 1, wherein the digital content is acquired via digital broadcasts, Internet, externally connected digital equipment, a hard disc, or a digital recording medium.

13. The information navigation apparatus according to claim 7, further comprising requesting means for requesting said available content being displayed by said display means.

14. The information navigation apparatus according to claim 13, further comprising means for indicating a treatment about the contents requested using said requesting means.

15. The information navigation apparatus according to claim 8, said modification means to modify the preference by referring to said user'"'"'s preferences being displayed by said display means.

16. The information navigation apparatus according to claim 8, said display means display newly available contents, which acquired by said preference analysis unit based on said modified user'"'"'s preference using said modification means.

17. The information navigation apparatus according to claim 1, wherein said database has a tree structure, wherein the tree structure has a content upstream and factors of preferences downstream which concerns and introduces to said content.

18. The information navigation apparatus according to claim 17, wherein the display means displays the newly available contents acquired from said tree structures based on the modified factors of preference.

19. The information navigation apparatus according to claim 1, wherein said apparatus is a remote control unit or a mobile terminal which can control the other apparatus for playing and /or storing said contents.

10. An information navigation method comprising:

storing content information about digital content;

storing a user'"'"'s content selection history;

analyzing a user'"'"'s preferences based on said content information and the user'"'"'s content selection history; and

displaying the result of analysis of said user'"'"'s preferences.

11. The information navigation method according to claim 10, further comprising allowing said user to modify the result of analysis of the user'"'"'s preferences that is being displayed.

12. An information navigation apparatus comprising:

a preference analysis unit for analyzing a user'"'"'s preferences; and

an information navigation function for facilitating the user'"'"'s information selection based on the analysis performed by said preference analysis unit such that the selection of information matches the user'"'"'s preferences.

20. An information navigation apparatus comprising:
