Digital Copy is a marketing term for a commercially distributed computer file containing a media product such as a film or music album. The term contrasts the computer file with the physical copy (typically a DVD or Blu-ray Disc) with which the digital copy is usually offered as part of a bundle.
There are two types of digital copy. The first is a copy already made in advance and included on the disc. The second is created dynamically from the DVD content itself. In both scenarios the publisher decides which content, formats, digital rights management (DRM) systems and technical parameters are used for the digital copy file. Digital Copy systems based on existing pregenerated files are less flexible than dynamic transcoding solutions.
Digital Copy files based on existing files include only one audio track and no subtitles, although the DVD itself may have multiple audio tracks and multiple subtitles. Also, the quality is limited by the bitrate used to encode the file which is typically relatively low and not adjusted to the device to be transferred to.
