- 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,
- 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.
