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.
