Dolby Digital EX
Dolby Digital EX is a 6.1-channel surround format
proposed by Dolby Laboratories that allows users
to enjoy in their homes the “DOLBY DIGITAL
SURROUND EX” audio format jointly developed by
Dolby Laboratories and Lucas Films.
The 6.1 channels of sound, including surround back
channels, provide improved sound positioning and
expression of space.
Dolby Digital Plus
Dolby Digital Plus is an improved Dolby Digital signal
format that is compatible with up to 7.1 channels
of discrete digital sound and also improves sound
quality thanks to extra data bit rate performance.
It is upwardly compatible with conventional Dolby
Digital, so it offers greater flexibility in response to
the source signal and the conditions of the playback
equipment.
Dolby Headphone
The Dolby Headphone technology provides
a surround sound listening experience over
headphones.
When listening to multichannel content such
as DVD movies over headphones, the listening
experience is fundamentally different than listening
to speakers. Since the headphone speaker drivers
are covering the pinna of the ear, the listening
experience differs greatly from traditional speaker
playback. Dolby utilizes patented headphone
perspective curves to solve this problem and
provides a non-fatiguing, immersive, home theater
listening experience. Dolby Headphone also
delivers exceptional 3D audio from stereo material.
Dolby TrueHD
Dolby TrueHD is a high definition audio technology

/ 24 bit resolution and up to 6 audio channels with
a sampling frequency of 192 kHz / 24 bit resolution.
Dolby TrueHD is adopted for applications that put
very high importance on sound quality. Dolby Virtual Speaker

and positioning) is achieved.
A realistic, powerful sense of presence is achieved
when playing movie sources in AV rooms as well.
