Abstract

Based on a content attribute serving as a coordinate axis of which the setting input is performed from an operation input unit, and the content identifier of a content of interest, a metadata storage unit is searched to select one or multiple other contents relating to the content of interest. The strength of relationship between each of the selected other contents and the content of interest is calculated based on the content attribute set as a coordinate axis, and information indicating correlation. The layout relations of other contents with the content of interest as the origin are calculated based on the content attribute serving as a coordinate axis, and the calculated strength of relationship. The display image of each of the other contents is disposed in accordance with the calculated layout relations.

7. The contents display device according to claim 1, wherein said metadata storage unit is configured to store access histories of a plurality of users as metadata for each of the plurality of contents;

and wherein said display control means is configured to reflect the access histories of said plurality of users on the display images of said two or more other contents displayed on said display screen.

8. The contents display device according to claim 1, further comprising:

instruction input means configured to receive instruction input to reduce a display distance between contents displayed on the display screen;

wherein said display control means is configured to display the display images of said content of interest and said two or more other contents in accordance with said reduced display distance, and to remove from the display screen, in response to the instruction input to reduce the display distance, one or more contents previously displayed on the display screen.

9. The contents display device according to claim 1, further comprising:

instruction input means configured to receive instruction input indicating a direction for moving a display image of said display screen in parallel;

wherein said display control means is configured to move the display images of the content of interest and the two or more other contents in parallel in the direction instructed.

10. The contents display device according to claim 1, wherein said two or more other contents include an advertising content.

11. The contents display device according to claim 1, wherein said metadata includes data regarding advertising information relevant to the content of interest;

and wherein the display control means is configured to display said advertising information in association with the display images of the content of interest and the two or more other contents on said display screen.

12. The contents display device according to claim 1, further comprising:

accepting means configured to accept an instruction to change from said content of interest to a new content of interest;

wherein said contents selecting means is configured to obtain one or more new other contents relevant to the new content of interest;

and wherein said relation calculating means is configured to calculate a new strength of relationship between each of the one or more new other contents and the new content of interest,

and wherein said layout relation calculating means is configured to calculate a new position at which to display each of the one or more new other contents in relation to the new content of interest positioned at the origin,

and wherein said display control means is configured to display the display images of said new content of interest and said one or more new other contents in accordance with the calculated new position.

13. The contents display device according to claim 1, further comprising:
