Abstract:
A reproducing apparatus for reproducing a video object recorded on an optical disc,at least one video object and program chain information showing a reproduction route for the at least one video object, being recorded on the optical disc, the program chain information including at least one set of cell information, each set of cell information specifying at least part of one of the at least one video object as a cell, the program chain information indicating a reproduction order of cells corresponding to the at least one set of cell information, each set of cell information specifying a corresponding cell by indicating ID information of a video object and display start and end times for the corresponding cell during reproduction, each video object including units of compressed data that can be reproduced independently, each of the compressed data units including a plurality of pictures that are displayed in a plurality of consecutive fields, the reproducing apparatus comprising: reading unit operable to read the video object and the program chain information from the optical disc; decoding unit operable to decode the read video object; display unit operable to output, for a purpose of displaying, pictures obtained by the decoder; control unit operable to control the reading unit, decoding unit, and display unit, wherein the control unit (1) receives an indication to select one of a plurality of sets of program chain information, (2) controls, based on the cell information included in the selected program chain information and the reproduction order shown by the selected program chain information, the reading unit and decoding unit to read compressed data units of the video object included in the corresponding cell in order and to perform decoding in units of compressed data units, and (3) controls, in response to pictures produced by the decoding unit, the display unit to display pictures starting from a picture for a field corresponding to the display start time included in the corresponding cell information and omitting display of pictures before the picture for the field corresponding to the display start time in a same compressed data unit.
