Dolby TrueHD Makes the PC the Center of an Advanced Home Theater
For PCs that support Blu-ray Disc (built-in players or burners, or external connected drives), Dolby TrueHD unlocks the full audio capabilities of the format. Not only does Dolby TrueHD bring the PC into the advanced home theater world, it enables the PC to serve as a capture and playback system for reference-quality downloadable music.
For playback through a home theater system, Dolby TrueHD is transported via HDMI® (High Definition Multimedia Interface) version 1.3 or later, a single-cable digital connection for audio and video.
The Power of Metadata
The powerful Dolby metadata parameters give content creators comprehensive control over how their artistry will be heard in the home.
Dialogue normalization (dialnorm) maintains consistent volume levels when switching between Dolby TrueHD and Dolby Digital or Dolby Digital Plus programming.
Dynamic range control enables reduced peak volume levels without impacting overall sound quality. It’s ideal for late-night viewing.
Downmixing allows the content creator to enable stereo playback from the original multichannel source, or provide an independent stereo “artist’s mix” that is incorporated into the Dolby TrueHD bitstream.
Three Presentations, One Bitstream
A single Dolby TrueHD stream can contain up to three separate mixes (presentations): a 7.1-channel surround mix, a 5.1-channel surround mix, and a two-channel “artist’s” stereo mix. This gives content creators the ability to tailor each mix for optimum listening on any playback system.
Ready for the Future
Dolby TrueHD can deliver up to 16 channels of pristine audio, so it is ready for any future HD streamed formats. On Blu-ray Disc today, it delivers up to eight full-range channels of 24-bit/96 kHz audio and supports up to 24-bit/192 kHz for stereo and 5.1 content.
