Title: Data processing apparatus, data processing method, and computer program

Abstract: Non-destructive editing of a movie stream recorded with management information attached thereto according to a predetermined standard format is performed. First, an entry for desired content from among real play lists is added to a virtual play list. In the virtual play list, a playback content editing operation is performed. The process of editing a virtual play list that does not contain content of an entity involves non-destructive editing that does not accompany editing of the content of an entity. In addition, non-destructive editing of a virtual play list only requires the updating of a management information file, and only involves an increase in the used amount of the recording medium by the additional amount of the management information even if a playback section is copied, thus improving user convenience.
