Abstract
A method to bind the use of a digital audio/video service data receiver to a network on which at least one services provider broadcasts access controlled and free digital audio/video services streams, the method having the steps: receiving by the receiver a periodic signal transmitted by a conditional access system server via the network, said periodic signal being processed by a run time software embedded in the receiver to check legitimacy of the network; displaying services available on the network only if said run time software recognizes the periodic signal as indicating network legitimacy; and checking operability of the run time software and if necessary taking actions to enforce limitation of using the receiver on the network checked as legitimate. The invention further discloses a receiver bound to a specific network configured to perform the method.
