Abstract:
A reproduction apparatus for reproducing data from a recording disk, said recording disk having a data area where data to be decoded is recorded, said data area storing management data required for reproducing data from the data area, storing control data, and having an interleaved block section where video signals that represent a plurality of scenes are divided and arranged as interleaved units, said interleaved units of different scenes being recorded on recording tracks in a mixed state, said control data being recorded in each of the interleaved units and describing information indicative of mixed-state arrangement of said interleaved units of different scenes and addresses indicative of next interleaved units comprising jump destinations of each scene,said reproduction apparatus comprising system control means that include:means for reading control data each time one of said interleaved units to which the control data belongs is reproduced, for identifying the information indicative of mixed-state arrangement of the interleaved units, and for determining addresses of next interleaved units comprising next jump destinations of each scene,means, responsive to operational information regarding scene switching, for controlling a read position at which data is read from the recording disk, so as to change a reproduction stream of one of said interleaved units by referring to the addresses of the next interleaved units corresponding to the scene included in the control data; andmeans for determining jump destinations of said next interleaved units corresponding to respective scenes on the bases of the control data included in the interleaved units that are acquired at the read position, so as to accommodate scene switching.
