Amazon Superbit Listing
Superbit was a brand of premium DVD-Video versions of motion pictures from Columbia TriStar Home Video, a division of Sony Pictures Entertainment. Superbit DVDs aimed to improve picture quality over a standard DVD edition of a feature by increasing the bit rate of the encoded video. Audio quality was also improved by the mandatory inclusion of both Dolby Digital and DTS 5.1 surround audio tracks.
