Abstract
A method for managing access to scrambled broadcast or transmitted events received from a variety of service providers (including broadcast television networks, cable television networks, digital satellite systems). Each service provider employs the same public key for descrambling the access information message thereby permitting a user to access events from various service providers without changing the smart card. The method may also be expanded to manage access to a scrambled package of broadcast events.
