Improvements in receivers for television signals

摘要

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.
