Abstract

An information processing device includes: a subsidiary content storage unit configured to store and manage a subsidiary content which is created by editing processing secondarily using at least one content as editing material and which includes a main unit portion which is data for reproducing the actual content of the subsidiary content, and directly used content information which is added information, indicating what the directly used content, which is a content directly secondarily used at the time of creating the subsidiary content, is; and an importance setting unit configured to set importance based on secondary usage state of the directly used content regarding which importance is to be set, by other subsidiary contents, by using the directly used content information, so as to set importance regarding at least subsidiary contents stored and managed by the subsidiary content storage unit.

Claims

1. An information processing device comprising:

subsidiary content storage means configured to store and manage a subsidiary content which is created by editing processing secondarily using at least one content as editing material, said subsidiary content including

a main unit portion which is data for reproducing an actual content of the subsidiary content, and

directly used content information which is added information, indicating what directly used content, which is a content directly secondarily used at a time of creating the subsidiary content, is; and

importance setting means configured to set importance based on a secondary usage state of the directly used content regarding which importance is to be set, by other subsidiary contents, by using said directly used content information, so as to set the importance regarding at least subsidiary contents stored and managed by said subsidiary content storage means.

2. The information processing device according to claim 1, wherein said importance setting means sets the importance for subsidiary contents regarding which said importance is to be set, based on a number of subsidiary contents which are direct children of the subsidiary contents regarding which said importance is to be set, said number having been obtained using at least said directly used content information.

3. The information processing device according to claim 2, wherein the number of subsidiary contents which are direct children is obtained handling subsidiary contents, which are direct children and which have a same creator, as one subsidiary content.

4. The information processing device according to claim 1, wherein said importance setting means sets the importance for subsidiary contents regarding which said importance is to be set, based on a number of subsidiary contents which are offspring of the subsidiary contents regarding which said importance is to be set, said number having been obtained using at least said directly used content information.

5. The information processing device according to claim 4, wherein the number of subsidiary contents which are offspring is obtained handling subsidiary contents, which are direct children and which have a same creator, as one subsidiary content.

6. An information processing method comprising the step of:

setting importance for at least

a subsidiary content which is created by editing processing secondarily using at least one content as editing material, said subsidiary content including

a main unit portion which is data for reproducing the actual content of the subsidiary content, and

directly used content information which is added information, indicating what directly used content, which is a content directly secondarily used at a time of creating the subsidiary content,

which is stored in a storage unit;

wherein said importance is set based on a secondary usage state of the directly used content regarding which importance is to be set, by other subsidiary contents, by using said directly used content information.

7. A program causing an information processing device to execute the step of:

setting importance for at least

a subsidiary content which is created by editing processing secondarily using at least one content as editing material, said subsidiary content including

a main unit portion which is data for reproducing an actual content of the subsidiary content, and

directly used content information which is added information, indicating what directly used content, which is a content directly secondarily used at a time of creating the subsidiary content,

which is stored in a storage unit;

wherein said importance is set based on a secondary usage state of The directly used content regarding which importance is to be set, by other subsidiary contents, by using said directly used content information.

8. An information processing device comprising:

a subsidiary content storage unit configured to store and manage a subsidiary content, said subsidiary content including

a main unit portion which is data for reproducing an actual content of The subsidiary content, and

directly used content information which is added information, indicating what directly used content, which is a content directly secondarily used at a time of creating the subsidiary content, is; and

an importance setting unit configured to set importance based on a secondary usage state of the directly used content regarding which importance is to be set, by other subsidiary contents, by using said directly used content information, so as to set the importance regarding at least subsidiary contents stored and managed by said subsidiary content storage unit.
