摘要： A data copying system of the present invention includes a data copying apparatus for copying data recorded on a first recording medium to a second recording medium. The data copying apparatus includes: a data read section for reading out the data from the first recording medium; a data modification control section for controlling modification of the data in accordance with modification control information, the modification control information being provided for controlling the modification of the data; and a data write section for writing an output of the data modification control section to the second recording medium. The modification control information includes a copying permission flag indicating whether the copying of the data permitted, a quality control flag for controlling a quality of modified data which is obtained by modifying the data, and a billing control flag for controlling billing for the copying of the data. The data modification control section determines whether billing is required for the copying of the data in accordance with the billing control flag. When the billing is required, the data modification control section controls the modification of the data in accordance with the copying permission flag and the quality control flag, after confirming that the billing has been done by the billing apparatus. When the billing is not required, the data modification control section controls the modification of the data in accordance with the copying permission flag and the quality control flag, without confirming that the billing has been done by the billing apparatus.

摘要： A content playback apparatus (digital watermark detection apparatus) comprises: a detection unit operable to detect a digital watermark from audio data having a plurality of blocks, the audio data being contained in a content which is to be played back along a playback time-line; a detected block storage unit for storing therein information indicating a block in which the digital watermark has been detected by the detection unit; and a playback control unit operable to play back all data contained in the content other than audio data corresponding to the block indicated by the information stored in the detected block storage unit. This makes it possible, even when audio data containing copyright information is inadvertently recorded on a camcorder, to prevent the audio data containing the copyright information from being played back, thereby enabling users to view the content without the influence of playback control.

摘要： To provide a terminal device with which, even if content that has undergone conversion is moved to another device, the content before the conversion can be used when moving the content from the device which is a move destination of the content back to a move source of the content. The terminal device stores the content in advance, applies an irreversible conversion which causes a decrease in quality to the content to generate converted content, and writes the converted content to a storage medium. The terminal device encrypts a block in the content using an encryption key to generate an encrypted block, replaces the block in the content with the encrypted block, and writes the encryption key to the storage medium.
