Also known as E-AC3 or DD+, this is a lossy compression format designed to replace the Dolby Digital [[AC3]] system. The advantages of DD+ over AC3 are several encoder based enhancements, as well as support for higher bitrates and up to 13.1 channels of audio at 96 kHz with 24-bit depth. Up to 6 Mbps streams are supported. DD+ is mandatory for [[HD DVD]], meaning all HD DVD players must be able to decode DD+ to LPCM or downmix to a legacy format. DD+ is only optional for [[Blu-ray]], meaning all discs with DD+ audio must also carry a separate legacy AC3 track.
