Deep Color

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, etc., bits when the receiver
corresponds to Deep Color. 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.

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 the 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.

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 colorations.

DTS

Digital audio compression technology
developed by Digital Theater Systems, Inc. This
technology conforms to 5.1-channel surround.
This format comprises of stereo rear channel and
there is discrete subwoofer channel in this
format. DTS provides the same 5.1 discrete
channels of high quality digital audio. The good
channel separation is realized due to the all
channel data being recorded discretely and
processed in digitally.

HDMI

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.

PCM (Pulse Code Modulation)

A method of converting analog audio to digital
audio for easy enjoyment of digital sound.

S-AIR (Sony Audio Interactive Radio
frequency)

Recent times have seen the rapid spread of DVD
media, Digital Broadcasting, and other high-
quality media.
To ensure that the subtle nuances of these high-
quality media are transmitted with no
deterioration, Sony has developed a technology
called “S-AIR” for the radio transmission of
digital audio signals with no compression, and
has incorporated this technology into the EZW-
RT10/EZW-RT10A/EZW-T100.
This technology transfers digital audio signals
with no compression using the 2.4 GHz band
range of ISM band (Industrial, Scientific, and
Medical band), such as wireless LANs and
Bluetooth applications.

S-Force PRO Front Surround

Sony’s long-term involvement in surround
technology (and the vast amounts of acoustic
data accumulated as a result) has led to the
development of all-new processing method and
advanced DSP to handle this task effectively,
which we call S-Force PRO Front Surround.
Compared with previous front surround
technologies, S-Force PRO Front Surround
reproduces a more convincing sense of distance
and space, resulting in a true surround sound
experience without the need for rear speakers.
