It is desirable that consumer DVD players (and computer software for playing conventional DVD movies) be able to play the video data that is encoded on the DICOM DVD. The MPEG2 bit stream that is “encapsulated” by the DICOM Transfer Syntax is potentially re-usable by such applications, if the appropriate UDF structure is created to share the same extent between the DICOM file and the file format and folder structure used by the consumer DVD Video format. Alternatively, the bit stream could be duplicated and both sets of files present on the same piece of media.
This profile does not require this, nor specify which approach to take. Specifically, this profile does not require that a DVD Video file and folder structure be present, though it is recommended.
