  • Conditional access system and smartcard for use in conditional access system
    Patent number: 9237309
    Abstract: Embodiments of the invention include a conditional access system comprising a terminal and a smartcard, wherein the terminal comprises a user interface for interaction with an end-user, comprising an output for displaying first user interaction data and an input for generating second user interaction data in response to the first user interaction data; and a descrambler configured for descrambling scrambled content, and wherein the smartcard is configured for generating the first user interaction data and allowing, in dependence of the second user interaction data received from the user interface, the descrambler to descramble the scrambled content.

  • CONDITIONAL ACCESS SYSTEM
    Publication number: 20090183004
    Abstract: The invention provides an improved conditional access system with efficient bandwidth usage on the interface between a receiver and a conditional access module. The conditional access system has a receiver, a selection module, a conditional access module and possibly a terminal. The conditional access module has a first memory for storing service identifiers of services and transmits one or more service identifiers to the selection module. The selection module receives an input signal from the receiver and selects from the input signal those sub-signals as identified by the service identifiers and transmits the sub-signals to the conditional access module.
