Analogue
Audio signals produced from L/R audio output
terminals of general equipment is called analogue
audio.
Surround signal
Audio signal made up of front speakers, center
speaker and surround speakers. For this unit,
surround signal is automatically played by Dolby
Virtual Speaker.
Sampling frequency
Sampling is the process of converting the heights of
sound wave (analogue signal) samples taken at set
periods into digits (digital encoding).
Sampling frequency is the number of samples
taken per second, so larger numbers mean faithful
reproduction of the original sound.
HDMI Standby mode
When this unit and TV (VIERA) and DIGA DVD
recorder are connected with HDMI cables, image/
audio from DIGA can still be transmitted to TV even
though the unit is turned off.
This is useful when you want to enjoy late night
viewing only with the television’s speakers.
Dynamic range
Dynamic range is the difference between the lowest
level of sound that can be heard above the noise of
the equipment and the highest level of sound before
distortion occurs.
Decoder, Decode
Decoder is the device to enable us to hear audio
data that is encoded on DVD, etc., as a normal
audio signal. This process is called decoding.
Digital
Blu-ray Disc players, DVD recorders, DVD players,
and CD players are usually equipped with digital
output terminals. Connect through the digital
terminal to enjoy digital surround systems such as
Dolby Digital and DTS.
Dolby Surround
Dolby Surround is a four-channel analogue
surround system, consisting of two front channels
(left and right) (stereo), a center channel for
dialogue (monaural), and a surround effect channel
(monaural), producing a dynamic and rich surround
effect. The surround channel plays a narrow range.
Optical
Using optical fibre cable for digital signal input/
output from DVD, CD, etc., provides better sound
quality for playback or recording compared to
analogue. Only possible with equipment that has an
optical terminal.
CPPM (Content Protection for Prerecorded Media)
This is the copyright protection technology which
prevents file copy of DVD audio.
Dolby Digital (DVD etc.)
Digital surround system developed by Dolby
Laboratories.
Dolby Pro Logic
ΙΙ
This system can process not only Dolby Surround,
but also other 2-channel sources to produce a 5.1-
channel sound for a more realistic sound field. It is
also possible to enhance old movies recorded in
stereo with this dynamic 5.1-channel sound. This
unit uses Dolby Pro Logic
ΙΙ
to add surround effects
to stereo sources such as video cassettes and CDs.
Dolby Virtual Speaker
This system allows you to enjoy a surround effect with
two front speakers, a center speaker, and a subwoofer.
This is not merely a “virtual surround” effect, but rather
uses the optimal speaker arrangements and listening
positions for 5.1-channel sound.
DTS (Digital Theater Systems)
Digital surround system developed by DTS, Inc.
This surround system is used in many movie
theaters around the world. There is good separation
between the channels, so realistic sound effects are
possible.
HDMI (High Definition Multimedia Interface)
HDMI is a next-generation digital interface for
consumer electronic products. Unlike conventional
connections, it transmits uncompressed digital
video and audio signals on a single cable. This
unit supports high-definition video output (720p,
1080i) from the HDMI AV OUT terminal. To enjoy
high-definition video, a high-definition compatible
television is required.
PCM signal (CD, DVD audio, etc.)
Analogue sounds are converted to a digital
bitstream signal. This is the type of digital audio
signal used for CD, DVD audio, etc.
5.1 Channel surround
Monaural and stereo use one channel and two
channels respectively to reproduce sound, but
5.1-channel surround uses 5 speakers and a
low frequency effect channel. The 5 channels
are: 1 center speaker, 2 front speakers, and 2
surround speakers at the side of or to the rear of
the sitting position. Sound output of the subwoofer
is much narrower than the other speakers, and so
is considered as 0.1. This is called 5.1-channel
surround when played through all 5.1 channels, and
with this unit you can achieve a similar effect with
Dolby Virtual Speaker.
