SMARTCARD FOR USE WITH A RECEIVER OF ENCRYPTED BROADCAST SIGNALS, AND APPARATUS AND METHOD FOR BROADCASTING ENCRYPTED SIGNALS BY USING THE SMART CARD

摘要

A smartcard for use with a receiver of encrypted broadcast signals comprises a microprocessor for enabling or controlling decryption of said signals. A memory is coupled to the microprocessor. The microprocessor is adapted to enable or control the individual decryption of a plurality of such signals from respective broadcast suppliers of such signals by means of respective dynamically created zones in the memory, the dynamically created zones each being arranged to store decryption data associated with a respective one of said broadcast suppliers.
