Glossary
x A.F.D. (Auto Format Direct)
A function that automatically detects the input
audio signal format for optimal processing.
Recorded or encoded sound is faithfully
reproduced without added sound effects such
as reverb, etc.
x A/V SYNC
When the video lags behind the audio signal,
this function can be used to delay the audio for
synchronizing the audio and video.
x Component video
A format for transmitting video signal
information consisting of three separate
signals: luminance Y, chrominance Pb, and
chrominance Pr. High quality pictures, such as
DVD video or HDTV pictures, are transmitted
more faithfully. The three jacks are color-
coded green, blue, and red.
x Composite video
A standard format for transmitting video
signal information. The luminance signal Y
and chrominance signal C are combined and
transmitted together.
x Crossover frequency
The frequency at which two speaker’s
frequencies intersect.
x Dolby Digital
Digital audio encoding/decoding technology
developed by Dolby Laboratories, Inc. It
consists of front (L/R), center, surround (L/R)
and sub-woofer channels. It is a designated
audio standard for DVD-video and also known
as 5.1ch surround. Since surround information
is recorded and reproduced in stereo, more
realistic sound with fuller presence is
delivered than with Dolby surround.
x Dolby Digital Surround EX
Acoustic technology developed by Dolby
Laboratories, Inc. Surround back information
is matrixed into regular left and right surround
channels so that the sound can be reproduced
in 6.1ch. Active scenes, especially, are
recreated with a more dynamic and realistic
sound field.
x Dolby Pro Logic II
This technology converts 2ch stereo recorded
audio into 5.1ch 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 5.1ch surround sound.
x Dolby Pro Logic IIx
Technology for 7.1ch (or 6.1ch) playback.
Along with audio encoded in Dolby Digital
Surround EX, 5.1ch Dolby Digital encoded
audio can be reproduced in 7.1ch (or 6.1ch).
Furthermore, existing stereo recorded content
can also be reproduced in 7.1ch (or 6.1ch).
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 4ch surround sound.
This is the most common audio processing
method for DVD-video.
x Downmix
A method to output multi-channel audio such
as 5.1ch, encoded into two channels.
x DSD (Direct Stream Digital)
Audio format used for a Super Audio CD.
DSD converts analog signals to digital and
records them directly, without adding any
processing, so that no information is omitted.
Recording and playback of high fidelity,
quality sound is achieved.
x DTS 96/24
A high sound quality digital signal format. It
records audio at a sampling frequency and bit
rate of 96kHz/24bit which is the highest
possible for DVD-video. The number of
