摘要

A system and method described herein provide stereoscopic video using standard DVD video data combined with enhancement data. In various embodiments, the enhancement data may be stored on the same DVD as the standard video, or provided via downloading and/or streaming to a stereoscopic DVD player. When stored on the DVD, the enhancement data is provided in various forms, including MPEG (-1 or -2) program stream level; or the MPEG elementary stream level. In one embodiment, the enhancement data consists of a difference signal between left- and right-eye images taken on a pixel-by-pixel basis. The present invention also pertains to an optical disc player with a standard digital port, such as a USB port, coupled to an external storage, such as a thumb drive, coupled to a standard digital port such as a USB port. The external storage may also be used to provide content, commands or applications that enable the player to present certain additional content, or to perform certain additional or enhanced functions.
