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 Extent111P as part of a frame data Extent designated by an OUT_point of the item, the Imaginary Extent111P being reproduced within the preceding PlayItem, and the current PlayItem is considered to have an Imaginary Extent111C as part of a frame data Extent indicated by an IN_point of the item, the Imaginary Extent111C being reproduced within the current PlayItem. A control unit of a DV recording/reproducing apparatus compares each of the Imaginary Extents111P and111C 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.
