Abstract
A content processing system for use in an electronic apparatus includes a unit for acquiring first revocation list information corresponding to a first media type, and a unit for recording the first revocation list information on a recording medium of a second media type. The recorded first revocation list information is used in authentication between the electronic apparatus and the recording medium of the second media type.
Claims12
A content processing system in an electronic apparatus, comprising:
- a data processing unit capable of reading/writing data from/to a recording medium of a first media type detachably connected to the electronic apparatus and a recording medium of a second media type;
- a first interface configured to interface the data processing unit with said recording medium of the first media type;
- and
- a second interface configured to interface the data processing unit with said recording medium of the second media type,
- the data processing unit including:
- a first device driver configured to control said recording medium of the first media type via the first interface;
- a second device driver configured to control said recording medium of the second media type via the second interface;
- a revocation list acquiring unit configured to acquire, via the first interface, first revocation list information recorded on said recording medium of the first media type by using the first device driver;
- and
- a revocation list recording unit configured to record, via the second interface, the first revocation list information on said recording medium of the second media type by using the second device driver, the recorded first revocation list information being used in authentication between said electronic apparatus and said recording medium of the second media type.
A content protecting method applied to an electronic apparatus having a data processing unit capable of reading/writing data from/to a recording medium of a first media type detachably connected to the electronic apparatus and a recording medium of a second media type, the method comprising:
- loading, via a first interface, first revocation list information recorded on said recording medium of the first media type by using a first device driver which controls said recording medium of the first media type;
- recording, via a second interface, the loaded first revocation list information on said recording medium of the second media type by using a second device driver which controls said recording medium of the second media type;
- and
- using the recorded first revocation list information in authentication between said electronic apparatus and said recording medium of the second media type.
