Glossary
Audio formats/Decoding
Dolby
The Dolby technologies are explained below.
See http://www.dolby.com for more detailed
information.
Dolby Digital
Dolby Digital is a multichannel digital audio
coding system widely used in cinemas, and
in the home for DVD and digital broadcast
soundtracks.
Dolby TrueHD
Dolby TrueHD is the lossless encoding technol-
ogy developed for high-definition optical discs
in the upcoming era.
Dolby Digital Plus
Dolby Digital Plus is the audio technology for
all high-definition programming and media. It
combines the efficiency to meet future broad-
cast demands with the power and flexibility to
realize the full audio potential expected in the
upcoming high-definition era.
Dolby Digital Surround EX
Dolby Digital Surround EX (the EX stands for
EXtended) is an extension of Dolby Digital
encoding whereby a surround back channel
is matrixed into the surround left/right chan-
nels for 6.1 channel playback. This allows for
compatibility with Dolby Digital 5.1 channel
decoding, as well as for decoding using Dolby
Digital EX.
Dolby Pro Logic IIx and Dolby Surround
Dolby Pro Logic IIx is an improved version of the
Dolby Pro Logic II (and Dolby Pro Logic) decod-
ing system.
Dolby Surround is an encoding system which
embeds surround sound information within
a stereo soundtrack, which a Dolby Pro Logic
decoder can then use for enhanced surround
listening with greater sound detail.
Dolby Pro Logic IIz
Adding a pair of speakers above the front left
and right speakers adds expressiveness in the
vertical direction to the previous horizontally-
oriented sound field. The height channel
strengthens the sound field’s sense of three-
dimensionality and air, producing presence and
expansion.
DTS
The DTS technologies are explained below.
See http://www.dts.com for more detailed

DTS Neural Surround can generate 7.1 chan-
nel surround sound from any matrixed stereo
source (such as video or TV).
Decoding
A technology for converting digital signals
that have been compressed upon recording
by a digital signal processing circuit, etc., into
