摘要： When a content management apparatus (110) is a copy origin and a recording medium (120) is a copy destination, and when the copy origin holds content copy enabled count control information and a content is copied from the copy origin to the copy destination, the copy enabled count control information held by the copy origin prior to the copy processing is updated according to a predetermined rule, so as to create copy enabled count control information held by the copy origin and copy enabled count control information held by the copy destination. Copy processing at the copy origin after is performed according to the copy enabled count control information held by the copy origin and copy processing of the content recorded in the recording medium (120) after is performed according to the copy enabled count control information recorded in the recording medium (120). Thus, it is possible to realize content management which is easily be understood by a user.

摘要： A management apparatus (FIG. 1) stores pairs of copyrighted contents and numbers of permitted check-outs. On being requested to perform check-out for a semiconductor memory card, the management apparatus records an audio object (AOB) corresponding to a content in the semiconductor memory card, assigns a content ID to the AOB, and decrement a corresponding number of permitted check-outs. An editing and playback apparatus edits the AOB and assigns a content ID, which is the same as the content ID of the original AOB, to each new AOB obtained by the editing. A local storage holds history information including a media ID and the content ID assigned to the original AOB. On being requested to perform check-in for the semiconductor memory card, the management apparatus sets, in a non-playable state, the AOB assigned a content ID that is the same as the content ID in the history information and increments the number of permitted check-outs.
