发明名称 Recording/reproduction device and method for digital broadcasting
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.
