Abstract
Equipment (2, 15) is used for the reception of multimedia presentations and for their playback to the user, said equipment comprising a storage and presentation apparatus such as a computer (16) or television (3) and a terminal of a bidirectional communications system such as a mobile phone (4) or cordless phone (19). The multimedia information is loaded dynamically, and keys needed to descramble scrambled transmissions are delivered to the user via a bidirectional communications system. In the terminal equipment a local agent (14) which uses only a little of system capacity takes care of information loading and checks the available resource. Bidirectional communications can also be used for making payments to the producer and/or distributor of the multimedia service in the form of operations similar to telebank services.
