Abstract
A data reproducing apparatus for recording/reproducing a multiplexed bit stream has a detection circuit for detecting information regarding attribute of data from the bit stream during reproduction and an output unit for outputting the detected information regarding the attribute of data and the bit stream.
Claims18
A data reproducing apparatus, comprising:
- (a) reproducing means for reproducing bit stream data in which coded data of a plurality of programs are multiplexed, from a recording medium on which the bit stream data is recorded, the bit stream data also including attribute data for discriminating each of the plurality of programs included in the bit stream data;
- (b) detecting means for detecting the attribute data from the bit stream data reproduced by said reproducing means;
- and
- (c) output means for parallel outputting the attribute data detected by said detection means and the bit stream data reproduced by said reproducing means.

A data reproducing method comprising the steps of:
- reproducing bit stream data in which coded data of a plurality of programs are multiplexed, from a recording medium on which said bit stream data is recorded;
- reproducing means for reproducing bit stream data in which coded data of a plurality of programs are multiplexed, from a recording medium on which the bit stream data is recorded, the bit stream data also including attribute data for discriminating each of the plurality of programs included in the bit stream data;
- detecting the attribute data from the bit stream data reproduced in said reproducing step;
- and
- parallel outputting the attribute data detected in the detecting step in the bit stream data reproduced in the reproducing step.
