    • A Hard Disk Recorder (HDR) (3) is arranged to receive signals signals defining television programmes and television programme schedule data. The HDR receives 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 hard disk (16) for recording received television programmes. A remote control (28) is provided to select television programmes to be recorded from the displayed 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 received in different channels. Also, the HDR is operable to replay a currently broadcast programme offset in time. The time offset can be overcome by playing 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 use these transition signals, for example, to skip between transitions in previously recorded programmes replayed from the hard disk.
    • 硬盘记录器(HDR)(3)被布置成接收定义电视节目和电视节目安排数据的信号信号。 HDR在专用节目安排数据频道中基本上恒定地接收更新的节目时间表数据。 HDR被布置成输出用于在电视屏幕(2)上显示的节目安排数据。 HDR包括用于记录所接收的电视节目的硬盘(16)。 提供遥控器(28)以根据所显示的节目表选择要记录的电视节目。 此外,HDR被布置成接收包括在每个接收到的电视频道中的附加节目安排信息,该信息用于控制硬盘以根据时间表记录预编程的电视节目。 硬盘可操作以同时记录在不同频道中接收的两个不同的电视节目。 此外,HDR可用于在时间上重播当前广播节目偏移量。 可以通过以增加的帧速率在时间偏移内播放节目的一部分来克服时间偏移。 此外,HDR被布置为接收指示节目的各部分之间的转换的转换信号,例如广告和“实际”节目之间的转换。 HDR可操作地使用这些转换信号,例如,跳过先前记录的从硬盘重放的程序的转换。
