Dolby TrueHD is a lossless audio coding technology designed for applications in high-definition disc media and other contexts where the quality of the programming demands playback accuracy that is bit-for-bit identical to the original performance. Expanding upon the proven foundation of MLP Lossless™, Dolby TrueHD is further defined by expanded bit rates (up to 18 Mbps), additional channel offerings (eight full-range channels), enhanced stereo mix support, and the introduction of metadata functionality (including dialogue normalization and dynamic range control). Dolby TrueHD is mandated for HD-DVD players and is an optional feature in the Blu-ray Disc™ format. Through the use of HDMI™, Dolby TrueHD bitstreams can also be decoded in A/V receivers.
The ADI implementation of Dolby TrueHD Decoder on SHARC has been fully tested using all Dolby certification tests according to Dolby requirements.
Each module supports the Analog Devices, Inc. (ADI) Blackfin or SHARC Processor family and is a licensed product that is available in object code format. Recipients must sign or accept a license agreement with ADI prior to being shipped or downloading the modules identified in the license agreement.
