Glossary

Album
Section of a music or picture piece on a data
CD containing MP3 audio tracks or JPEG
image files.
Chapter
Subdivision of a title on a DVD. A title is
composed of several chapters.
Dolby Digital
This sound format for movie theaters 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.
Futhermore, 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 advantages 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 mode
The Movie mode is for use with stereo
television shows and all the 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 mode
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 rear 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.
