Abstract

A digital content editing apparatus that edits a content having license information defining a grant for a reusing operation or a multiple content including a plurality of the contents includes: a reuse license processor that obtains a constraint indicative of a condition on reuse between a content or the multiple content and a content other than the content or the multiple content from the license information of the content or the multiple content; an instruction generator that generates an operation execution instruction of reusing the content or the multiple content according to the constraint obtained by the reuse license processor; a reusing unit that reuses the content or the multiple content based on the operation execution instruction generated by the instruction generator; and an editor that edits the content or the multiple content reused by the reusing unit.

Claims

a reusing unit that reuses the content or the multiple content based on the operation execution instruction generated by the instruction generator, and

an editor that edits the content or the multiple content reused by the reusing unit.

2. The digital content editing apparatus according to claim 1, wherein the reuse license processor obtains, as the constraint, a complementary constraint indicative of a relation of master and servant at the time of using the content or the multiple content together with another content or another multiple content, and

the instruction generator generates an operation execution instruction of reusing the content or the multiple content having the complementary constraint together with another content or another multiple content to be subjected to the complementary constraint according to the complementary constraint obtained by the reuse license processor.

3. The digital content editing apparatus according to claim 2, wherein the reuse license processor obtains, as the complementary constraint, a spatial constraint indicative of a positional relation on a reuse screen at the time of using the content or the multiple content together with another content or another multiple content, and

the instruction generator generates an operation execution instruction of disposing the content or the multiple content according to the positional relation on the reuse screen defined in the spatial constraint obtained by the reuse license processor.

4. The digital content editing apparatus according to claim 2 or 3, wherein the reuse license processor obtains, as the complementary constraint, a structural constraint indicative of a structural inclusive relation at the time of using the content or the multiple content together with another content or another multiple content, and

the instruction generator generates an operation execution instruction of disposing the content or the multiple content according to the structural inclusive relation defined in the structural constraint obtained by the reuse license processor.

5. The digital content editing apparatus according to claim 1, wherein the reuse license processor obtains, as the constraint, an exclusive constraint indicative of a relation of inhibiting the content or the multiple content from being used together with another content or another multiple content, and

the instruction generator generates an operation execution instruction of exclusively reusing the content or the multiple content and the another content or the another multiple content according to the exclusive constraint obtained by the reuse license processor.

6. The digital content editing apparatus according to claim 5, wherein the instruction generator generates an operation execution instruction of not reusing the content or the multiple content having the exclusive constraint when another content or another multiple content inhibited to be used together with the content or the multiple content is reused according to the exclusive constraint obtained by the reuse license processor.

7. The digital content editing apparatus according to claim 5, wherein the instruction generator generates an operation execution instruction of not reusing another content or another multiple content inhibited to be used together with the content or the multiple content when the content or the multiple content having the exclusive constraint is reused according to the exclusive constraint obtained by the reuse license processor.

8. A digital content editing method of editing a content having license information defining a grant for a reusing operation or a multiple content including a plurality of the contents, comprising:

a reuse license processing that obtains a constraint indicative of a condition on reuse between the content or the multiple content and a content other than the content or the multiple content from the license information of the content or the multiple content;

an operation execution instruction generation that generates an operation execution instruction of reusing the content or the multiple content according to the constraint obtained by the reuse license processing;
