    • A recording/reproduction device is provided wherein service content having interactivity can be restored even when recorded. In recording mode, a transport stream from a receiving device 34 is received and a conversion device 36 converts this to a packet-multiplexed stream in a condition suitable for recording, which is then output as a converted stream. The conversion device 36 selects packets relating to a desired service from the transport stream and, of these packets, selects only packets needed for reproduction and uses these to generate a converted stream. A recording device 38 records this converted stream on a recording medium 44. In reproduction mode, the converted stream from recording medium 44 is read by means of a reading device 42 and supplied to a restoration device 40. Restoration device 40, in accordance with the content of this converted stream, restores and outputs a service content signal (for example a composite signal such as NTSC). A video/image output device 46 receives this service content signal and outputs video/images. These are recorded, still in packetized condition. Consequently, since recording can be achieved including the control data, recording/reproduction can be formed without impairing the functionality of the satellite broadcast provided by the control data.
    • 提供了一种记录/再现装置,其中即使在记录时也可以恢复具有交互性的服务内容。 在记录模式中,接收来自接收装置34的传输流,并且转换装置36将其转换成适合于记录的条件的分组复用流,然后将其作为转换流输出。 转换装置36从传输流中选择与期望业务有关的分组,并且这些分组仅选择再现所需的分组,并使用它们来生成转换流。 记录装置38将该转换的流记录在记录介质44上。 在再现模式中,通过读取装置42读取来自记录介质44的转换流,并将其提供给恢复装置40。 恢复装置40根据该转换流的内容恢复和输出服务内容信号(例如,诸如NTSC的复合信号)。 视频/图像输出装置46接收该服务内容信号并输出​​视频/图像。 这些都被记录,仍然处于打包状态。 因此,由于可以实现包括控制数据的记录,所以可以形成记录/再现,而不会损害由控制数据提供的卫星广播的功能。
