x Deep Color (Deep Colour)
Video signals for which the color depth of
signals passing through an HDMI jack have
been raised.
The number of colors that could be expressed
by 1 pixel was 24 bits (16,777,216 colors) with
the current HDMI jack. However, the number
of colors which can be expressed by 1 pixel
will be 36 bits, etc., when the receiver
corresponds to Deep Color (Deep Colour).
Since the gradation of the depth of a color can
be expressed more finely with more bits,
continuous color changes can be more
smoothly expressed.
x Digital Cinema Sound (DCS)
A unique sound reproduction technology for
home theater developed by Sony, in
cooperation with Sony Pictures Entertainment,
for enjoying the exciting and powerful sound
of movie theaters at home. With this “Digital
Cinema Sound” developed by integrating a
DSP (Digital Signal Processor) and measured
data, the ideal sound field intended by
filmmakers can be experienced at home.
x Dolby Digital
Digital audio encoding/decoding technology
developed by Dolby Laboratories, Inc. It
consists of front (left/right), center, surround
(left/right) and subwoofer channels. It is a
designated audio standard for DVD video and
also known as 5.1 channel surround. Since
surround information is recorded and
reproduced in stereo, more realistic sound with
fuller presence is delivered than with Dolby
surround.
x Dolby Digital Plus
Dolby Digital Plus provides the flexibility and
efficiency to deliver more channels of
compelling surround sound for high-definition
video media. Its superior coding efficiencies
enable up to 7.1ch of high-quality
multichannel audio without negatively
impacting bit budgets allocated for video
performance or additional feature sets.
x Dolby Digital Surround EX
Acoustic technology developed by Dolby
Laboratories, Inc. Surround back information
is matrixed into regular left and right surround
channels so that the sound can be reproduced
in 6.1 channel. Active scenes, especially, are
recreated with a more dynamic and realistic
sound field.
x Dolby Pro Logic II
This technology converts 2 channel stereo
recorded audio into 5.1 channel for playback.
There is a MOVIE mode for movies and
MUSIC mode for stereo sources such as
music. Old movies encoded in the traditional
stereo format can be enhanced with 5.1
channel surround sound.
x Dolby Pro Logic IIx
Technology for 7.1 channel (or 6.1 channel)
playback. Along with audio encoded in Dolby
Digital Surround EX, 5.1 channel Dolby
Digital encoded audio can be reproduced in
7.1 channel (or 6.1 channel). Furthermore,
existing stereo recorded content can also be
reproduced in 7.1 channel (or 6.1 channel).
x Dolby Pro Logic IIz
Dolby Pro Logic IIz brings a vertical aspect to
the sound field through the addition of left and
right front high speakers. It decodes
nondirectional elements in the audio mix and
reproduces them from the high speakers,
giving an enhanced sense of depth and airiness
to the sound field.
x Dolby Surround (Dolby Pro
Logic)
Audio processing technology developed by
Dolby Laboratories, Inc. Center and mono
surround information is matrixed into two
stereo channels. When reproduced, audio is
decoded and output in 4 channel surround
sound. This is the most common audio
processing method for DVD video.
