    摘要: It is an object of the present invention to provide an apparatus not causing inconsistency between the original picture and the image for performing the operations even under the special playback mode. A transport stream from a receiver 34 is supplied to a converter 36. The converter 36 generates a data stream for normal playback. If a desired service contains control data for interactive operations, a data stream for normal playback containing the control data is generated. Also, selecting packets required for performing special playback generate a data stream for special playback. None of the control data is contained in the stream for special playback. Both the stream for normal playback and the stream for special playback are recorded on a recording medium 44. In the normal playback mode, reproduction under interactive manner is performed in accordance with the control data for interactive operation. No inconsistency is produced between the original picture and the image for performing the operations because none of the image for interactive operations is displayed.

    摘要: 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.
