Abstract
A collective content consisting of a plurality of partial contents holding license information including a use condition can be appropriately used according to the use condition contained in the license information in each of the partial contents. A content use control device includes an input/output I/F, license generation unit, output control unit, content reproduction unit, and use control unit. The partial content holding the license information including the use condition is inputted via the input/output I/F. License information is assigned to each of the partial contents inputted and constituting a collective content. Single license information collecting the assigned license information and its collective content are outputted to a recording medium. The content use control device reproduces a partial content contained in the collective content recorded on the recording medium and controls the use of the reproduced partial content according to its use condition.
