Abstract:
A method for access control to a digital scrambled content distributed to a set of installed reception terminals including one master terminal and at least one slave terminal dependent on the master terminal. In the method the slave terminal systematically or occasionally returns at least one item of information about the access condition to the master terminal through a point-to-point link, to enable the master terminal to control access of the slave terminal to the content.
