Information recording medium, information recording device and method for reproducing audio information and still picture information simulataneously

An information recording apparatus comprising:

• a first recording unit which records object data formed by multiplexing a first stream including still picture information and a second stream including audio information by a unit of packet;
• and
• a second recording unit which records reproduction control information comprising:
• first reproduction sequence information which designates reproduction sequence of the first stream by a first unit and which includes time information indicating a reproduction start timing of the first unit;
• reproduction time information which indicates whether each still picture of the still picture information of the first stream is a finite value or an infinite value, and which indicates a reproduction time of the still picture whose reproduction time is the finite value;
• first type information which indicates a type of the first unit;
• first storage position information which indicates a storage position of the object data designated by the first unit;
• second reproduction sequence information which designates
• reproduction sequence of the second stream, and which includes audio repeat information indicating whether or not the audio information of the second stream is to be repeatedly reproduced;
• second type information which indicates a type of the second stream;
• and
• second storage position information which indicates a storage position of the object data designated by the second reproduction sequence information,
• wherein the first recording unit and the second recording unit record the object data and the reproduction control information separately at different areas.
