Dolby demonstrates first public demonstration of Dolby Digital Plus for HD

November 16, 2004

The AES Show marked the first public demonstration of Dolby Laboratories’ Dolby Digital Plus, the audio codec designed for next-generation audio, video delivery and audio storage system technologies such as HD-DVD and hard-disk-drive (HDD) media.

The DVD Forum recently selected the Dolby Digital Plus as a standard audio format for HD-DVD. It offers bit-rate and channel extendibility and is an extension of the Dolby Digital format, the audio compression standard for DVD-Video players.

These extensions to the existing Dolby Digital format extend the peak data rate from 640kb/s up to 6Mb/s. Additionally, the format is designed to offer discrete channel coverage beyond the current 5.1 standard, such as 7.1 discrete channels and more.
