Abstract :
This paper presents a simulation of an access control system that deals with the problem of access control and copyright protection for broadcasted image-related services. The services that concentrate our interest include mainly Pay-TV, but also the existing and forthcoming multimedia services which are expected to share the same channels as digital TV for their diffusion in the future. We assume that these services have the basic characteristic of interactivity, which implies the existence of a return channel for the users to the service providers. The simulation is concentrated on the basic operations provided by the system, that make it flexible and, at the same time, make possible or help the access control and the billing of the services
