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.
