A.F.D. (Auto Format Direct) AUTO
The auto decoding function automatically
detects the type of audio signal being input
(Dolby Digital, DTS, or standard 2 channel
stereo) and performs the proper decoding if
necessary. This mode presents the sound as it
was recorded/encoded, without adding any
effects (e.g. reverberation).
However, if there are no low frequency signals
(Dolby Digital LFE, etc.), it will generate a low
frequency signal for output to the subwoofer.
Album
Section of a music piece on a data CD
containing MP3 audio tracks.
Chapter
Subdivision of a title on a DVD. A title is
composed of several chapters.
DCS (Digital Cinema Sound)
In the collaboration with Sony Pictures
Entertainment, Sony measured the sound
environment of their studios and integrated the
data of the measurement and Sony’s own DSP
(Digital Signal Processor) technology to
develop “Digital Cinema Sound”. “Digital
Cinema Sound” simulates in a home theater an
ideal movie theater sound environment based on
the preference of movie director.
Dolby Digital
This sound format for movie theatres is more
advanced than Dolby Pro Logic Surround. 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” because the subwoofer channel is
counted as 0.1 channel (since it functions only
when a deep bass effect is needed). All six
channels in this format are recorded separately
to realize superior channel separation.
Furthermore, since all the signals are processed
digitally, less signal degradation occurs.
Dolby Pro Logic Surround
As one method of decoding Dolby Surround,
Dolby Pro Logic Surround produces four
channels from two-channel sound. Compared
with the former Dolby Surround system, Dolby
Pro Logic Surround reproduces left-to-right
panning more naturally and localizes sounds
more precisely. To take full advantage of Dolby
Pro Logic Surround, you should have one pair of
surround speakers and a center speaker. The
surround speakers output monaural sound.
Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from two-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.
• Dolby Pro Logic II Movie
The Movie mode is for use with stereo television
shows and all programmes encoded in Dolby
Surround. The result is enhanced soundfield
directionality that approaches the quality of
discrete 5.1-channel sound.
• Dolby Pro Logic II Music
The Music mode is for use with any stereo music
recordings, and provides a wide and deep sound
space.
DTS
Digital audio compression technology that the
Digital Theater Systems, Inc. developed. This
technology conforms to 5.1-channel surround.
The surround channel is stereo 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 because the all channel
data is recorded discrete and processed in
digital.
