    摘要: 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.

    摘要: A recording and reproducing apparatus for recording and reproducing the stream of a content, in which video image and audio streams are extracted from streams of a predetermined format, and a new stream, the edit of which can be freely carried out, is created from the streams and recorded. A recording and reproducing apparatus comprises an input/output interface for inputting a stream, a stream conversion processing portion for converting an input stream of a predetermined format into a stream comprising only a video image stream and an audio stream and a recording medium writing control portion for writing and recording the converted stream in a recording medium. The recording medium writing control portion writes managing information representing that the stream converted by the stream conversion processing portion is recorded in a predetermined area (manufacturer definition area) of the recording medium. The recording and reproducing apparatus can control various functions (display function, edit function, reproduction function, output function, dubbing function, and so forth) according to the managing information.

    摘要: When data whose storage period is limited by copy control information is temporarily stored in a removable recording medium, the data are encrypted and decoding information (encryption key) necessary to decrypt the encrypted data is held on the device side. By doing so, the data cannot be used beyond a permitted period of the temporary storage. A storage device has an external input/output I/F for removably connecting a removable recording medium; a reception section for receiving copy control information and data (such as video data), the storage period of which data is limited by the copy control information; an encrypting section for encrypting the received data; and a control section for storing the encrypted data in the removable recording medium and storing decryption information (encryption key), necessary to decrypt the encrypted data, in a place in the storage device, outside the removable recording medium. The data stored in the removable recording medium can be reproduced only by the storage device.

    摘要: There is provided an accounting system for accounting a content distributed by an accumulation broadcast or a removable recording medium while preventing an unauthorized use and holding privacy of a user. An accounting ID specifying the money information stored in a prepaid card is read and a content ID of the encrypted content specified by the user and the accounting ID are reported to an accounting server. Decoding information is acquired in return for the accounting and the encrypted content is decoded by using the decoding information so as to be used.
