Embodiment Construction

[0077] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0078] According to an embodiment of the present invention, multi-angle support is enabled so that angle data is recorded on an information storage medium by using a separate recording method instead of an interleave method. In other words, multi-angle support is realized by recording bit streams for each angle data in adjacent recording areas of the information storage medium. During data reproduction, angle change is realized by dividing data for each angle into jump units (JPU), designating the start address of the JPU as a jump point, and recording information about the jump point of each angle data For additional jump point information. According to an aspect of...

Abstract

An information storage medium controls a multi-angle data reproducing apparatus by having a data structure including at least one clip for each angle, each angle clip being a data record unit of the multi-angle data for an angle. Each angle clip is divided into predetermined jumping units at jumping points and each is recorded in contiguous areas of the information storage medium. Using the clip jumping points as a link among the angle clips in which each angle clip is contiguously recorded provides efficient random access for reading the multi-angle data for angle change.

Description

[0001] This application is a divisional application of a patent application entitled "Information storage medium with multi-angle data structure and its equipment" with application date of October 13, 2003 and application number 200380101470.7. technical field [0002] The present invention relates to an information storage medium having a structure for multi-angle data and a recording and reproducing apparatus thereof. Background technique [0003] A digital versatile disc (DVD) is a representative example of a conventional information storage medium on which multi-angle data can be recorded. Multi-angle data is recorded on a DVD by using an interleaving method in which data is divided into predetermined units and the units are alternately recorded. [0004] Hereinafter, a video (including audio, as the case may be) data structure of a DVD as a conventional multimedia storage medium will be described with reference to the accompanying drawings. FIG. 1 is a diagram of a con...
