Abstract:
A method for conditionally allowing fruition of broadcast contents, broadcast by a contents broadcaster and received by a user by means of a receiving equipment, includes: performing, locally at the receiving equipment of the user, a first fruition entitlement check based on first fruition entitlement data available locally at the receiving equipment; having the receiving equipment provide to the contents broadcaster the first fruition entitlement data exploiting a return communications channel of the receiving equipment; having the contents broadcaster perform a second fruition entitlement check based on a comparison between the received first fruition entitlement data and second fruition entitlement data available locally to the contents broadcaster; and conditioned on a result of the second check, having the contents broadcaster provide to the receiving equipment, exploiting the return communications channel, a fruition entitlement confirmation notification; at the receiving equipment, conditioning the fruition of the broadcast contents based on the receipt of the fruition entitlement confirmation by the contents broadcaster.
