Abstract

In an information delivery system, a security device (SD) manages an access to information (INF). The security device (SD) is capable of providing a pointer (PO) which indicates a location (LO) from which additional data (ADA) may be obtained. The additional data (ADA) may be a description of the information (INF) which is offered. For example, in a pay TV system, the information (INF) may be a particular movie of which the description is 'James Bond, Dr. No, action category, 12 years and older, broadcast April 19, at 20h30.' In that case, the pointer (PO) may be used to inform a subscriber that his security device (SD) allows him to watch this particular movie. However, the additional data (ADA) contained in the location (LO) indicated by the pointer (PO), may also be software for various purposes such as, for example, playing games or configuring a receiver (REC) which co-operates with the security device (SD).
