Not very specific, but here is the blurb;
Dolby Debuts Dolby TrueHD, 'Picture-Perfect' Sound for
Next-Generation HD Discs
Dolby Laboratories announced its latest advancement in lossless audio
technology, Dolby TrueHD, which is designed to complement the recent
developments in high-definition optical disc formats. With Dolby
TrueHD, home theater viewers will experience audio performance equal
to the highest-resolution studio masters currently available.
The company is demonstrating Dolby TrueHD along with Dolby Digital
Plus at its CEDIA Expo. These two Dolby technologies are essential
elements of next-generation high-definition entertainment, having been
adopted for use in both the HD DVD and Blu-ray Disc formats. Dolby
TrueHD and Dolby Digital Plus technologies are mandatory audio codecs
in the HD DVD format as well as optional features in the Blu-ray Disc
format. Dolby Digital is mandatory in both formats.
"The high-definition disc formats being discussed today will provide
viewers with new levels of image quality," said Craig Eggers, Dolby
Senior Manager, Consumer Electronics Technology Marketing. "With Dolby
TrueHD, those same viewers can experience multichannel surround sound
that fully complements the detail and fidelity of the high-definition
picture."
Dolby TrueHD builds upon the proven foundation of MLP Lossless(TM) by
incorporating higher bit rates, additional channels, enhanced stereo
mix support, and extensive metadata functionality, including dynamic
range control and dialogue normalization. Enabling recordings that are
bit-for-bit identical to studio masters, MLP Lossless was first
introduced in DVD-Audio, and has since become the leading multichannel
lossless audio format. In addition, Dolby TrueHD provides support for
all of the new speaker locations designated by the Society of Motion
Picture and Television Engineers (SMPTE) for digital cinema
applications (RP 226).
"When coupled with high-definition video, Dolby TrueHD offers an
exceptional home theater experience that enables you to enjoy sound as
stunning as the picture," said Ed Schummer, Senior Vice President and
General Manager of the Consumer Division, Dolby Laboratories. "When a
playback system displays the Dolby TrueHD logo, viewers are assured
they are hearing the highest-quality audio performance possible -- as
if they are hearing the studio master itself."
