x Deep Colour
Video signals for which the colour depth of
signals passing through an HDMI jack have
been raised.
The number of colours that could be expressed
by 1 pixel was 24 bits (16,777,216 colours)
with the current HDMI jack. However, the
number of colours which can be expressed by
1 pixel will be 36 bits, etc., when the system
corresponds to Deep Colour.
Since the gradation of the depth of a colour can
be expressed more finely with more bits,
continuous colour 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
This movie theater sound format is more
advanced than Dolby Surround Pro Logic. In
this format, the surround speakers output
stereo sound with an expanded frequency
range, and a subwoofer channel for deep bass
is independently provided. This format is also
called “5.1” with the subwoofer channel
designed as 0.1 channel (since it functions
only when a deep bass effect is needed). All
six channels in this format are recorded
separately for superior channel separation.
Furthermore, since all the signals are
processed digitally, less signal degradation
occurs.

x Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from 2 channel sources. This
is done using an advanced, high-purity matrix
surround decoder that extracts the spatial
properties of the original recording without
adding any new sounds or tonal colourations.

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.

Digital audio encoding/decoding technology
for theaters developed by DTS, Inc. It
compresses audio less than Dolby Digital,
delivering a higher quality sound
reproduction.

x HDMI (High-Definition
Multimedia Interface)
HDMI (High-Definition Multimedia
Interface) is an interface that supports both
video and audio on a single digital connection,
allowing you to enjoy high quality digital
picture and sound. The HDMI specification
supports HDCP (High-bandwidth Digital
Contents Protection), a copy protection
technology that incorporates coding
technology for digital video signals.

x L.F.E. (Low Frequency Effects)
Sound effects of low frequencies which are
output from a subwoofer in Dolby Digital or
DTS, etc. By adding a deep bass with a
frequency between 20 to 120 Hz, audio
becomes more powerful.
