Abstract:
In the case that data such as AV data is recorded in a recording apparatus and/or in the case that data is reproduced by a reproduction apparatus, there is no concrete mechanism that protects copyright.
An encryption means 11 for encrypting AV data sent from an interface 4, a control means 14 for controlling the encrypted AV data to be recorded and a recording means 15 controlled by the control means 14 for recording the encrypted AV data in a magnetic disk are provided such that the control means 14 controls the recorded data to be reproduced, the recording means 15 is controlled by the control means 14 so as to reproduce the data recorded on the disk and a decryption means 12 decrypts the reproduced data that is sent to the interface.
