The DVD Forum is planning to study (the “Proposed Study”) the possible incorporation of 3D movie technology into The DVD Forum format specifications for DVD-Video and HD DVD-Video (the “DVD Format Specifications”). The DVD Forum plans to study only the feasibility and potential merit of incorporating 3D movie technology into the DVD Format Specifications. Please note that The DVD Forum has made no decision to incorporate such technology into the DVD Format Specifications and does not intend to select any specific 3D movie technology for inclusion at this time. After studying each proposed 3D movie technology, The DVD Forum will decide whether 3D movie technology should be incorporated into the DVD Format Specifications. As part of this study, The DVD Forum may also consider whether measures to achieve compatibility with existing DVD-Video and HD DVD-Video players would also need to be implemented in the event 3D movie technology is incorporated into the DVD Format Specifications.
