<p>By installing a device control module (DCM), a functional component module (FCM), and a guarantee card FCM of a digital video cassette recorder (DVCR) into an integrated receiver decoder (IRD), the IRD is able to control the DVCR. The guarantee card FCM is used for accessing an electronic guarantee card stored in a non-volatile memory of the DVCR. The IRD stores purchase information or repair information of the DVCR into the non-volatile memory of the DVCR via an IEEE-1394 serial bus in response to an instruction from a requester. The IRD also reads the purchase information or the repair information from the non-volatile memory of the DVCR via the IEEE-1394 serial bus. <IMAGE></p> |
