SOLUTION: In a configuration to control the use of the contents based on content control units (CPS units), this processor identifies the application type corresponding to the recording contents when recording or reproducing the contents, and records or reproduces data through the processing matching each application type. For example, it sets up the application types corresponding to the real-time recording contents and to downloaded contents, and also the unit key matching each type and the content control units to make flexible control matching each type.
