Abstract
A master decoder for use with a master smart card and at least one slave decoder for use with a slave smart card are arranged in a pay tv system, wherein the master decoder receives slave entitlement messages from a central management device and writes the slave entitlement messages to the slave smart cards when the slave smart cards are inserted in the master decoder. This ensures that the slave decoders are used within close proximity of the master decoders, such as in the same dwelling.
