• 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.
• Dolby Digital
Digital audio encoding/decoding technology
developed by Dolby Laboratories, Inc, It
consists of front (left/right), center, surround
(leftlright) and subwoofer channels, It is a
designated audio standard for DVD-video and
also known as 5,1 channels surround, Since
surround information is recorded and
reproduced in stereo, more realistic sound with
fuller presence is delivered than with Dolby
surround,
• Dolby Pro Logic II
This technology converts 2 channels stereo
recorded audio into 5,1 channels 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
channels surround sound,
• 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 channels surround
sound, This is the most common audio
processing method for DVD-video,
• DTS Digital Surround
Digital audio encoding/decoding technology
for theaters developed by DTS, Inc, It
compresses audio less than Dolby Digital,
delivering a higher quality sound
reproduction,
• 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.
• 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.
• Sampling frequency
To convert analog audio to digital, analog data
should be quantified, This process is called
sampling, and the number of times per second
the analog data is quantified is called the
sampling frequency, A standard music CD
stores data quantified at 44,100 times per
second, which is expressed as a sampling
frequency of 44,1 kHz, Generally speaking, a
higher sampling frequency means better sound
quality,
