A pesar de todo este rollete que sueltan en el link, sigo sin enterarme en qué consiste, y en que se diferencia de pcm de alta resolución.

8. Is Dolby TrueHD a lossless format?
Yes. Dolby TrueHD always provides a fully
lossless audio signal.
9. Is every application of Dolby TrueHD
lossless?
Yes.
10. What will I hear when content is encoded
in Dolby TrueHD?
You will hear the original source content
as it was recorded.
11. How does Dolby TrueHD differ from other
lossless formats?
All lossless audio formats must ensure that
the audio is always delivered with bit-for-bit
accuracy. The core technology of Dolby TrueHD,
MLP LosslessTM, pioneered lossless audio
on DVD-Audio. As a result, MLP Lossless
technology has been in use longer and more
widely than any other lossless audio format
and has proven itself to consumers and
industry experts alike.
But that is only part of the story. The Dolby
TrueHD decoder circuit actually verifies the
output is lossless as it is decoding. Dolby
TrueHD also provides unique support for
stereo playback, either via a programmable
downmix or a wholly separate stereo mix,
ensuring that surround content creators can
deliver the companion stereo mix exactly as
they intend, without compromise.
12. How does Dolby TrueHD differ from
MLP Lossless?
Dolby TrueHD expands on the proven
capabilities of MLP Lossless, adding the ability
to deliver more flexible channel configurations,
higher data rates, and extended metadata
functionality to support next-generation
content delivery formats.
13. What is the sampling frequency and word
length for multichannel Dolby TrueHD?
Dolby TrueHD for next-generation highdefinition
media delivers sampling frequencies
from 48 to 192 kHz and word lengths from
16 to 24 bits.
