Dolby Laboratories announces that Dolby audio technologies have been selected as mandatory formats for both HD-DVD and Blu-ray Disc. The DVD Forum has selected Dolby Digital Plus and MLP Lossless as mandatory audio formats for HD-DVD. The Blu-ray Disc Association announced that Dolby Digital will be a mandatory technology on its new format, the Blu-ray Disc. Both discs are next-generation packaged media formats designed to deliver high-definition picture quality.

The DVD Forum's selection of Dolby Digital Plus as a mandatory audio standard assures future compatibility of HD-DVD software media and playback devices with the more than 39 million A/V receivers equipped with Dolby Digital in homes today. Additionally, DVD-Video software titles will retain full audio compatibility with next-generation HD DVD-Video players.
