Sony has ended production of its so-called Superbit DVDs to focus on promotion of Blu-ray. The Superbit process was designed to improve the video encoding and audio playback of discs.
Superbit is doubling the bitrate used for video encoding and offers DTS and Dolby 5.1. Because the process is using greater disc capacity, the Superbit titles did not include extras.
The technology never caught up. Sales of Superbit DVDs were said to account for only 2% of a title available in both standard and Superbit versions, the latter being slightly more expensive. Since 2000, some 57 titles using Superbit technology were produced. The Cirque du Soleil was the last Superbit disc produced by Sony in April 2005.
