Abstract

The present invention is intended to detect, when a meta data author inputs a viewpoint and viewpoint score to contents having time information, time information of the contents corresponding to the input time of the viewpoint and viewpoint score input, assign corresponding time information to the viewpoint and viewpoint score input and create meta data related to the viewpoint and viewpoint score.

Claims

1. A meta data creation apparatus comprising:

a viewpoint score input section for at least one author to input an arbitrary viewpoint and a viewpoint score of said viewpoint to a content of contents having time information; and

a meta data creation section that detects, when said author inputs said viewpoint and viewpoint score, said time information of said contents corresponding to the input time of said viewpoint and viewpoint score and creates meta data with said detected time information assigned to said input viewpoint and viewpoint score.

2. The meta data creation apparatus according to claim 1, further comprising a viewpoint score assignment table with said viewpoint and viewpoint score assigned to keys provided for said viewpoint score input section, wherein when said key is depressed, said meta data creation section references said viewpoint score assignment table and designates said viewpoint and viewpoint score corresponding to said key as the viewpoint and viewpoint score corresponding to said contents.

3. The meta data creation apparatus according to claim 1, further comprising a contents creation section that creates contents having said time information from input contents, wherein said viewpoint and viewpoint score are input to the contents having said time information created by said consents creation section.

4. The meta data creation apparatus according to claim 1, further comprising a contents decoding section that decodes encoded contents having time information and creates contents having said time information, wherein said viewpoint and viewpoint score are input to the contents having said time information created by said decoding section.

5. The meta data creation apparatus according to claim 1, further comprising:

a meta data storage section that stores said meta data created;

a viewpoint score reading section that reads said viewpoint and viewpoint score from meta data stored in said meta data storage section;

a viewpoint score display section that displays said viewpoint and said viewpoint score read;

a viewpoint score selection section that selects an arbitrary viewpoint and viewpoint score from said viewpoints and viewpoint scores displayed; and

a viewpoint score editing section for editing said viewpoint and viewpoint score selected.

6. The meta data creation apparatus according to claim 1, wherein said contents having time information are constructed of at least one medium of moving images, voice, text, three-dimensional images or animation.

7. The meta data creation apparatus according to claim 1, wherein said viewpoint and viewpoint score of meta data are at least one viewpoint of MPEG-7 or user definition.

8. The meta data creation apparatus according to claim 1, wherein said meta data is structurally described.

9. The meta data creation apparatus according to claim 2, wherein when said key is depressed consecutively, said meta data creation section designates the time information of said contents corresponding to the time at which said key was depressed before as a start time of said viewpoint and viewpoint score and designates the time information of said contents corresponding to the time at which said key was depressed after as an end time of said viewpoint and viewpoint score.

10. The meta data creation apparatus according to claim 2, wherein when said key is depressed consecutively, said meta data creation section designates the time information of said contents corresponding to a time shifted by a predetermined time from the time at which said key was depressed before as a start time of said viewpoint and viewpoint score and designates the time information of said contents corresponding to a time shifted by a predetermined time from the time at which said key was depressed after as an end time of said viewpoint and viewpoint score.

11. The meta data creation apparatus according to claim 2, wherein said meta data creation section designates the time information of said contents corresponding to the time at which said key was depressed as a start time of said viewpoint and viewpoint score and designates the time information of said contents corresponding to the time at which said key was released as an end time of said viewpoint and viewpoint score.

12. The meta data creation apparatus according to claim 2, further comprising a segmentation section that divides said contents into segments and creates said time information corresponding to a start time of said segment and creates said time information corresponding to an end time of said segment for each segment, wherein when said key is depressed, said meta data creation section designates said time information corresponding to said start time of said segment corresponding to the time at which said key was depressed as a start time of said viewpoint and viewpoint score and designates said time information corresponding to said end time of said corresponding segment as an end time of said viewpoint and viewpoint score.

13. The meta data creation apparatus according to claim 3, further comprising a contents display section that displays said input contents.

14. The meta data creation apparatus according to claim 4, further comprising a contents display section that displays contents having said time information decoded by said contents decoding section.

15. The meta data creation apparatus according to claim 5, wherein said viewpoint score display section displays said read viewpoints and viewpoint scores arranged in order of said time information.

16. A meta data input terminal comprising:

a viewpoint score input section for at least one author to input arbitrary viewpoints and viewpoint scores of said viewpoints to a content of contents;

a time generation section that generates an absolute time; and

a viewpoint transmission section that detects, when said author inputs said viewpoint and viewpoint score, said absolute time corresponding to the input time of said viewpoint and viewpoint score input, assigns said absolute time corresponding to said viewpoint and viewpoint score input and sends to other apparatuses via a network.

17. A meta data creation apparatus comprising:

a viewpoint score reception section that receives said viewpoint and viewpoint score and said absolute time corresponding to the input time of said viewpoint and viewpoint score sent from the meta data input terminal according to claim 16 via a network; and

a meta data creation section that creates meta data with said received absolute time to said viewpoint and viewpoint score.

18. A meta data creation method comprising the steps of:

detecting time information of contents corresponding to an input time of an arbitrary viewpoint and a viewpoint score of said viewpoint input by at least one author to a content of said contents having said time information; and

creating meta data with said detected time information assigned to said viewpoint and viewpoint score input.

19. A meta data creation method comprising the steps of:

detecting, through an input terminal, said absolute time corresponding to an input time of an arbitrary viewpoint and a viewpoint score of said viewpoint input by at least one author to a content of contents and sending said input viewpoint and viewpoint score with said detected absolute time assigned to a meta data creation apparatus via a network; and

receiving, through said meta data creation apparatus, said viewpoint and viewpoint score with said absolute time assigned sent from said input terminal and creating meta data with said received absolute time assigned to said viewpoint and viewpoint score.

20. A program that allows a computer to detect time information of contents corresponding to an input time of an arbitrary viewpoint and a viewpoint score of said viewpoint input by at least one author to a content of said contents having said time information and create meta data with said detected time information assigned to said viewpoint and viewpoint score input.
