发明名称 Kommunikationsnetz
摘要 The present invention relates to a network for communication between a central station (A) transmitting coded information and at least one receiver (C) able to receive these transmissions and to decode them in which, so as to check the number of users, the access entitlements of the users are determined by a limited number of special receivers but also by the necessity for authentication of each user before putting a receiver into operation. In order to facilitate the dialogue for identification and authentication between the transmitting central station and the user, the inventive receiver is also equipped with an interface (E) which allows remote authentication, and with a memory-card interface (H) which is equivalent to certain access rights. <IMAGE>
