1. An information processing apparatus for performing edit control of one or more AV streams recorded on a recording medium, the information apparatus comprising:
- edit control means for editing a play list including an attribute definition file defining an AV stream attribute provided as a pair with each AV stream file recorded on a recording medium and a plurality of play section data specifying a play section of an AV stream by a play start point and a play end point;
access control means for placing one or more entry marks for a user randomly accessing play-section data arranged on a time axis in a play list, forming a chapter by a section between adjacent entry marks and a section from a last entry mark to an end point of a last play-section data in the play list, and accessing an AV stream recorded on a recording medium for each chapter; and
play-list dividing means for dividing a chapter of a section defined by the user from the play list.

Abstract
A stream on a recording medium is divided into parts, and is subjected to rearrangement editing while the compatibility with a playback-only device is maintained.
By adopting a division processing procedure of a play item, rearrangement processing of a stream for each chapter is achieved. In a product specification, a plurality of real play lists are put together into a series of chapter groups to be presented to the user, and thus there are cases where rearrangement of chapters are closed in the same play list, and cases where the rearrangement extends over a plurality of play lists. Moreover, rearrangement editing, which moves a chapter between real play lists, between virtual play lists, and further from a real play list to a virtual play list, is performed.
