Abstract

An apparatus that does not cause inconsistency between an original picture and an image for performing operations under a special playback mode. A transport stream from a receiver is supplied to a converter. The converter generates a data stream for normal playback. If a desired service contains control data for an interactive operation, a data stream for normal playback containing the control data is generated. Packets required for performing the special playback are selected to generate a data stream for the special playback. None of the control data is contained in the special playback stream. The normal playback stream and the special playback stream are recorded on a recording medium. In the normal playback mode, reproduction under an interactive manner is performed in accordance with the control data for the interactive operation. No inconsistency is produced between the original picture and the image for performing the operations because none of the image for the interactive operation is displayed.

Claims

1. A digital transmitting apparatus that transmits a transport stream containing control data for realizing interactive operations, comprising:

a transmitter that transmits the transport stream with a special stream for special playback.

2. The apparatus of claim 1, wherein the special stream contains a control command that performs interactive operations.

3. The apparatus of claim 1, wherein the special stream does not contain a control command that performs interactive operations.

4. The apparatus of claim 3, wherein the special stream does not contain an image for interactive operations.

5. The apparatus of claim 3, wherein the special stream contains an image for interactive operations.

6. The apparatus of claim 1, wherein the special stream for special playback does not contain a control command to perform an interactive operation.

7. The apparatus of claim 6, wherein the special stream for special playback does not contain an image for interactive operations.

8. The apparatus of claim 6, wherein the special stream for special playback contains the control command that performs interactive operations.

9. A digital transmitting apparatus that transmits a transport stream containing control data for realizing interactive operations, comprising:

a transmitter that transmits the transport stream so as to contain a special stream for special playback containing a control command for performing interactive operations in addition to a normal stream for normal playback.

10. The apparatus of claim 9, wherein the special stream contains control data for performing interactive operations equivalent to that of the normal stream, the special stream for special playback also containing control data for performing interactive operations equivalent to that of the normal stream.

11. The apparatus of claim 9, wherein the special stream contains control data for performing interactive operations equivalent to that of the normal stream, the special stream for special playback containing control data for performing interactive operations in which a part of the control data is omitted.

12. The apparatus of claim 9, wherein the special stream contains control data in which a part of the control data included in the normal stream is omitted, the special stream for special playback containing control data in which a part of the control data included in the normal stream is omitted.

13. A digital transmitting apparatus, comprising:

a transmitter that transmits a transport stream containing control data for realizing interactive operations, wherein the transmitted transport stream contains information as to whether to allow a special playback.
