SYSTEM FOR STORING AND TRANSMITTING HOME NETWORK SYSTEM DATA

The invention specifies a system having a plurality of devices (2-7) which a re connected to one another via an IEEE 1394 interface and one (3) of which contains a control unit (11) which, when operated appropriately by a user, polls system data for devices (2,4-7) in this system via the interface (1) a nd passes this system data to an output unit (9, 13, 14) of this device (3). Th e device having the output unit is, by way of example, a set-top box (3) havin g a microprocessor which a user uses to poll system data for the devices (2, 4 - 7), which contains, in particular the input and output characteristics of th e latter, via the interface (1) and which the user can use to store this syste m data on a smart card (10) by means of a write/read device (9). Alternatively or at the same time, the system data can be shown on a display (13) or transmitted to a desired address via a modem connection (14). As a result, t he user of the system can receive expert advice from a specialist dealer or a customer service point regarding which devices (12) he can best add to his system; or if a point of failure or faults arise.
