摘要

In an information recording medium, object data made into a stream including those composed of a plurality of angle video information is recorded. Each of the angle video information, for example, is made of a set of GOPs. Each of the GOPs is segmented and stored in a packet. In an object data file, a switch unit as a logical delimiter for angle switching on the reproduction time axis is defined so that a plurality of packets containing the same GOP segmented will not be placed astride the boundary of the switch unit and the GOP which can be reproduced without using the GOP belonging to a switch unit preceding over the switch unit boundary is arranged as a first GOP of the switch unit in question. <IMAGE>
