A METHOD AND AN APPARATUS FOR INTERLEAVING BITSTREAM TO RECORD THEREOF ON A RECORDING MEDIUM, AND REPRODUCING THE INTERLEAVED BITSTREAM THEREFROM

摘要

AN INTERLEAVING METHOD FOR GENERATING A BITSTREAM FROM PLURAL VIDEO OBJECTS CONTAINING COMPRESSED VIDEO DATA BY ARRANGING IN THE PRESENTATION ORDER, WHEREIN INTERLEAVED DATA BLOCKS IN WHICH PLURAL VIDEO OBJECTS ARE CONTIGUOUSLY ARRAYED USING INTERLEAVED UNITS EACH LONGER THAN THE SHORTEST READ TIME ILVUMT SUCH THAT THE VIDEO OBJECT PRESENTATION START AND END POINTS ARE ALIGNED. THE RATIO BETWEEN THE PRESENTATION TIMES OF VIDEO OBJECTS WITH THE SHORTEST PRESENTATION TIME AND VIDEO OBJECTS OTHER THAN THOSE WITH THE SHORTEST PRESENTATION TIME IS WITHIN A RANGE OBTAINED FROM THE SHORTEST READ TIME ILVUMT, THE MAXIMUM JUMPABLE DISTANCE JM, AND THE SMALLEST CONTROL UNIT. CONTIGUOUS DATA BLOCKS WHEREIN THE PRESENTATION START POINTS AND END POINTS OF THE VIDEO OBJECTS ARRAYED THEREIN ARE NOT ALIGNED.
