A communications system includes a host computer (1) for sending a scrambled data body, descrambling data (10), and a loader (11). A plurality of terminals (2) is provided to receive transmissions from said host computer (1). A first communications link (4) is established between said host computer (1) and at least one of said plurality of terminals (2). A second communications link (3) is implemented for communicating said scrambled data body from said host computer (1) to said at least one of said plurality of terminals (2) in response to an individual request from that respective terminal (2). The terminal (2) may be provided with an external memory device (8) for storing the data body, descrambling data (10), and loader (11). <IMAGE> <IMAGE> |
