Abstract

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

Claims

1. Home system having a plurality of devices connected to one another via a home bus interface, in particular an IEEE 1394 bus interface, wherein one of the devices contains a control unit which, when operated appropriately by a user, polls system data for other devices in this system via the home bus interface, wherein said system data comprises characteristic data for a device, in particular a serial number, the manufacturer'"'"'s mark, the device class, output/input characteristics, the software version or any error data and passes this system data to an output unit of the one device, the output unit being a device for writing to a mobile, digital data medium which can store the system data, wherein the mobile, digital data medium is one of a smart card and a chip card having a memory, and in that, when operated appropriately by a user, the control unit in the one device stores system data for the connected other devices on one of the smart card and the chip card using the device.

2. Home system according to claim 1, wherein the one device having the device for writing to the data medium is one of a set-top box and a digital satellite receiver having a write/read device for one of a chip card and a smart card.

3. Home system according to claim 1, wherein the one device having the device for writing to the data medium is a minicomputer having a drive for one of a floppy disk and another data medium having one of a magnetic and optical storage medium.

4. Device for the home system according to claim 1, wherein the one device contains a control unit which, when operated appropriately by a user, polls system data for the connected other devices via an interface wherein the one device includes a device for writing to a mobile, digital data medium and wherein the device stores this system data on the data medium using the device.

5. Device for the home system according to claim 1, wherein the one device contains a control unit which, when operated appropriately by a user, or when an appropriate remote polling code is received, polls system data for the connected other devices via an interface wherein the one device includes a modem or another telecommunication connection which can send the polled system data to a desired address.

6. Device according to claim 5, wherein user operation corresponds to remote control in the context of a remote polling code transmitted via communication line or by radio.
