Abstract

A method comprises detecting zapping to or from one or more services; determining whether the zapping includes termination of a password-protected service; and sending a trigger message (248, 256, 262) only if the zapping includes termination of a password-protected service (X, Y, Z). In one embodiment, the trigger message is sent to a smartcard (SC). In one embodiment, the password-protected service is password-protected for parental control. In one embodiment, the method further includes requesting a password when the zapping includes zapping to a password-protected service. In one embodiment, the password-protected service is a pincode-protected service.
