Abstract
A method in which a network head-end associates with each segment of a list of at least one segment of a first segment block, a time datum that makes it possible to determine whether a deadline for sending an access rights request to an access rights server has changed; the network head-end sends to the terminal, together with each segment in the list, the associated time datum thereof; the terminal receives, together with each segment in the list, the associated time datum thereof, then changes a renewal deadline predetermined according to the last time datum received to obtain a new predetermined renewal deadline that enables the terminal to decide, according to the value thereof and at a given time before or equal to the changed deadline, to send an access rights request to the access rights server.
