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-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.
S-Master
S-Master is an all-digital amplifier technology
developed by Sony, which effectively minimizes
the occurrence of sound fragmentation and jitter,
delivering superb dialog clarity and faithful
reproduction of the original sound. The compact
amplifier section supports a higher power
efficiency and improved thermal performance.
x.v.Colour
x.v.Colour is a more familiar term for the
xvYCC standard proposed by Sony, and is a
trademark of Sony. xvYCC is an international
standard for color space in video.
This standard can express a wider color range
than the currently used broadcast standard.
