A Hard Disk Recorder (HDR) receives signals defining television programmes and programme schedule data. The HDR receives updated programme schedule data substantially constantly in a dedicated programme schedule data channel and outputs this data for display on a television screen. The HDR comprises a hard disk for recording programmes. A remote control selects programmes for recording from the displayed schedule. The HDR also receives schedule information included in each of the received television channels which information is used to control the hard disk to record pre-programmed programmes. The hard disk can simultaneously record two different television programmes received in different channels and to replay a currently broadcast programme offset in time. The HDR also receives transition signals indicating transitions between parts of programmes, such as advertisements and the “actual” programmes, which can be used to skip between transitions in recorded programmes replayed from the hard disk.

When an IC card is placed close to an IC card reader / writer in a hard disk recorder, the hard disk recorder writes the profile thereof including an IP address on the IC card. The hard disk recorder reads a card ID and a profile list including, for example, the profile of a television receiver from the IC card. Based on the card ID and the profile list, the hard disk recorder accesses the television receiver. The hard disk recorder notifies the television receiver of the profile list which is read from the IC card and to which the profile of the hard disk recorder has been newly added. The hard disk recorder thus establishes a virtual private network with the television receiver.
