Smart Card Security on STB

ABSTRACT

I developed a smartcard security and a DVB Common Interface (DVB-CI) module for television encryption on a STB. Television encryption is used to control access to paid television services, usually cable or satellite television services. To watch payable program channels, a DVB-CI module and a smartcard are necessary. When you are subscribed to more than one service provider, you must insert the proper smartcard or DVB-CI module with the matching smartcard to get access to each bouquet. If any smartcard or DVB-CI module with smartcard are not inserted in the receiver, only free (FTA; free-to-air) programs are available.
