Abstract
A terminal for receiving and re-transmitting information, comprises a first network adapter for receiving a primary data stream in which the information has been encoded, encrypted according to a key scheme from a primary transmitter through a first network in a first format, an arrangement for receiving entitlement messages, enabling an authorized receiver to decrypt the encrypted data stream, and at least one further network adapter for connection to a secondary network. The terminal is configured to re-transmit at least part of the information in at least one secondary data stream in a second format, differing from the first format, through the second network to at least one secondary terminal connected to the secondary network. The terminal is configured to transmit the secondary data stream(s) encrypted according to the same key scheme and to forward received entitlement messages that enable an authorized receiver to decrypt the secondary data stream(s) to the secondary terminal(s).
