Information processing device, information processing method, and program

An information processing method comprising:

• setting an indication of importance for at least a derivative content which is created by secondary editing using at least one content object as editing material, said derivative content including:
• a main unit portion comprising data for reproducing primary content that is referenced by the derivative content, wherein the primary content comprises audio and/or video, and
• directly referenced content information indicating directly referenced content, which comprises content directly referenced at a time of creating the derivative content, which is stored in a storage unit;
• wherein setting said indication of importance comprises setting the indication based on a secondary usage state of the derivative content, the secondary usage state reflecting use of the directly referenced content by at least one other derivative content different than the derivative content, the secondary usage state indicating that the at least one other derivative content is also dependent on the directly referenced content for playing back audio and/or video, the secondary usage state determined based on said directly used content information, and wherein setting the indication of importance further comprises setting the indication based on a held content list reflecting a list of directly referenced content objects held locally by a user.

At least one computer-readable non-transitory storage device storing computer-executable instructions that, when executed by at least one processor, cause an information processing device to execute:

• setting an indication of importance for at least a derivative content which is created by a secondary editing processing using at least one content as editing material, said derivative content including:
• a main unit portion which is data for reproducing an actual content of the derivative content, and
• directly used content information indicating a directly used content, which is a content directly used at a time of creating the derivative content, which is stored in a storage unit;
• wherein setting said indication of importance comprises setting the indication based on a secondary usage state of the derivative content, the secondary usage state reflecting use of the directly used content by at least one derivative content different than the derivative content, the secondary usage state indicating that the at least one other derivative content is also dependent on the directly referenced content for playing back audio and/or video, the secondary usage state determined based on said directly referenced content information, and wherein setting the indication of importance further comprises setting the indication based also on a held content list reflecting a list of directly referenced content objects held locally by a user.

An information processing device comprising:

• at least one processor executing stored program instructions;
• a derivative content storage unit configured to store and manage derivative content, said derivative content including
• a main unit portion comprising data for reproducing primary content that is referenced by the derivative content, wherein the primary content comprises audio and/or video, and directly referenced content information indicating directly referenced content, which comprises content directly referenced at a time of creating the derivative content;
• and
• an importance setting unit configured to set an indication of importance regarding the derivative content based on a secondary usage state of the derivative content and on a held content list reflecting a list of directly referenced content objects held locally by a user, the secondary usage state reflecting use of the directly referenced content by at least one other derivative content different than the derivative content, the secondary usage state determined based on said directly referenced content information.
