Abstract:
The present invention provides a stream recording/reproducing apparatus that records a stream onto a first recording medium without using extra recording capacity of such first recording medium, and then dubs such stream onto a second recording medium at high speed while minimizing the degradation in image quality and sound quality. The stream recording/reproducing apparatus of the present invention includes: an analysis unit ( 6 ) that judges whether or not a stream ( 101 ) is compliant with the logic specification of a second recording medium ( 7 ); a management information recording unit ( 8 ) that records a result of the judgment onto a first recording medium ( 3 ); a TS recording processing unit ( 2 ) that records the stream ( 101 ) onto the medium ( 3 ); processing units ( 14 ) and ( 15 ) that convert the stream ( 101 ) recorded on the medium ( 3 ) into a stream that is compliant with the logic specification of the medium ( 7 ) in the case where the stream ( 101 ) is not compliant with the logic specification of the medium ( 7 ); and a PS recording processing unit ( 17 ) that records the converted stream onto the medium ( 7 ).
