Superbit is a brand of premium DVD-Video versions of motion pictures from Columbia TriStar Home Video, a division of Sony. Superbit DVDs contain a reduced amount (and usually are completely devoid) of so-called added value and bonus material, such as documentaries or interviews, which can be found on regular DVDs. However, they are encoded at a bit rate that is, according to Sony, approximately twice as high as that of standard DVDs. This allows for an improved picture quality, especially on high end home cinema systems, while allowing viewers to choose between Dolby Digital (5.1) and DTS audio. Superbit discs can be read by regular DVD video players.
Sony's Superbit Collection has a limited number of titles, many of which are best-sellers that have been released again to allow buyers to benefit from the new format. Superbit DVDs are noticeably higher priced than regular ones.
Superbit should not be confused with either HD-DVD or Blu-ray (another optical disc technology used by Sony), both of which are different formats.
