IMPROVEMENTS IN RECEIVERS FOR TELEVISION SIGNALS

摘要

A Hard Disk Recorder (HDR) (3) is arranged to receive signals defining television programmes and television programme schedule data. The HDR receiv es updated programme schedule data substantially constantly in a dedicated programme schedule data channel. The HDR is arranged to output the programme schedule data for display on a television screen (2). The HDR comprises a ha rd disk (16) for recording received television programmes. A remote control (28 ) is provided to select television programmes to be recorded from the displaye d programme schedule. Furthermore, the HDR is arranged to receive additional programme schedule information included in each of the received television channels which information is used to control the hard disk to record pre- programmed television programmes according to schedule. The hard disk is operable to record simultaneously two different television programmes receiv ed in different channels. Also, the HDR is operable to replay a currently broadcast programme offset in time. The time offset can be overcome by playi ng back the part of the programme inside the time offset at an increased frame rate. Furthermore, the HDR is arranged to receive transition signals indicating transitions between parts of programmes, such as transitions between advertisements and the "actual" programmes. The HDR is operable to u se these transition signals, for example, to skip between transitions in previously recorded programmes replayed from the hard disk.
