ABSTRACT:
A broadband communication system (SYS), which is used to distribute television, radio and video signals, is additionally used for transmitting data signals from one subscriber (TN) to another subscriber (TN). The center (ZE) of the broadband communication system (SYS) has a service-on-demand server (SOD) which contains a control facility (CONTROL). The control facility (CONTROL) receives information transmitted by a subscriber (TN) via the return channel (R) to the center, performs a frequency conversion and transmits the information via the downstream channel (V) to all the subscribers (TN) of the broadband communication system (SYS). The information contains a source address, a destination address and the subscriber-specific data to be transmitted. Only subscribers (TN) whose address coincides with the destination address are able to interpret the information through a modem MODEM.
