x AAC
A digital audio coding format set as a standard
for digital satellite broadcasting. It is an
abbreviation for Advanced Audio Coding,
designed to realize CD-quality audio at a high
compression rate.
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 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.
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 colorations.

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.
x DTS Digital Surround
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.
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.
