Embodiment Construction

[0067] In the following description, a Clip AV stream file refers to a body of data (video data) composed of digital video and sound, made into a file format that can be handled by a file system, and recorded on a disc.

[0068]The following describes how part or all of this Clip AV stream file is specified so that necessary file parts can be arranged as desired and can be reproduced. FIG. 3 shows an application format of a simplified structure on a recording medium (recording medium 10 in FIG. 26, described later). As shown in FIG. 3, the PlayList is used to designate part or all of the Clip AV stream file so that only the desired part of the file is reproduced. From the user's point of view, PlayList is a single entity of video and sound. The simplest PlayList is formed by including recording data ranging from recording start to recording end. In the case of no editing, the recorded data generally constitutes a PlayList.

[0069] The PlayList is constituted by designating...

Abstract

This invention relates to a data recording apparatus, a data recording method, a program storage medium, and a program whereby data recorded on an information recording medium is edited and reproduced in a suitably controlled manner. Where an AV stream file including PlayItems is edited, the preceding PlayItem is considered to include an Imaginary Extent 111P as part of a frame data Extent designated by an OUT_point of the item, the Imaginary Extent 111P being reproduced within the preceding PlayItem, and the current PlayItem is considered to have an Imaginary Extent 111C as part of a frame data Extent indicated by an IN_point of the item, the Imaginary Extent 111C being reproduced within the current PlayItem. A control unit of a DV recording / reproducing apparatus compares each of the Imaginary Extents 111P and 111C with a minimum Extent size in order to establish connection_condition information. This invention may be applied advantageously to DV recording / reproducing apparatuses for recording video data to an optical disk.

Description

technical field [0001] The present invention relates to a data recording device, a data recording method, a program storage medium, and a program. More particularly, the present invention relates to a data recording device, a data recording method, a program storage medium, and a program in which data stored on an information recording medium is retrieved and edited in an appropriately controlled manner so as to reproduce appropriately ordered video data. Background technique [0002] A method for highly efficiently compressing AV (Audio Video) signals is the so-called DV (Digital Video) method. This encoding method is disclosed in the publication "Specification of Consumer-Use Digital VCRs Using 6.3mm Magnetic Tape" by The HD DIGITAL VCRCONFERENCE. The DV method is mainly applied to a camcorder (camera-integrated video tape recorder) using a video cassette tape. [0003] DV signals are input and output through an IEEE (Institute of Electrical and Electronics Engineers) 13...
