LFE (Low Frequency Effect) 0.1
Channel
This channel is for the reproduction of low bass signals.
The frequency range for this channel is 20 Hz to 120 Hz.
It is added to the full-range 5 channels in Dolby Digital
and DTS to enhance low frequency sound for added
effect. This channel is counted as 0.1 because it only
enforces a low frequency range.
Linear PCM (LPCM)
A signal that is changed to digital format without
compression. A CD is recorded with 16-bit sound at
44.1kHz, while DVD recording is anywhere from 16 bits
at 48 kHz to 24 bits at 192 kHz, which makes it a higher
quality sound than CD. This signal also has a type called
Packed PCM (P.PCM) that can be compressed without
any loss of data.
Matrix 6.1
CinemaStation incorporates a Matrix 6.1 decoder for
Dolby Digital and DTS multi-channel software that
enables 6.1-channel reproduction by adding the surround
back channel to existing 5.1-channel format. (The
surround back channel is created from surround left and
right channels, and output from a virtual surround back
speaker.) With this additional channel, you can
experience more dynamic and realistic moving sound
especially scenes with "fly-over" and "fly-around"
effects.
NTSC
NTSC is a video signal system (525 lines, 30 frames per
second) used in North America, Central America, a
number of South American countries, and some Asian
countries, including Japan.
Pan & Scan and Letter Box
In general, DVD Video is produced for viewing on a
wide television screen with an aspect ratio of 16:9. This
means you can now view most material with the
intended aspect ratio on a wide-screen television.
This ratio will not fit on a standard television that has an
aspect ratio of 4:3. Two picture styles, Pan & Scan and
Letterbox, deal with this problem.
• Pan & Scan cuts off the left and right portions of the
picture to fill the screen.
• Letterbox inserts black bands at the top and bottom of
the picture to reproduce an aspect ratio of 16:9.
PAL
PAL is a video signal system (625 lines, 25 frames per
second) used in the United Kingdom, much of the rest of
western Europe, several South American countries, some
Middle East and Asian countries, several African
countries, Australia, New Zealand, and other Pacific
island countries.
Sampling Frequency and Quantized
Bit Rate
When converting an analog signal to digital, the number
of times the signal is sampled per second is called the
sampling frequency while the degree of fineness when
converting the sound level into a numeric value is called
the quantized bit rate.
The frequency band that can be played back is
determined by the sampling rate while the dynamic
range expressing the difference in sound level is
determined by the quantized bit rate. In principle, the
higher the sampling rate, the wider the frequency range
that can be played back. And the higher the quantized bit
rate the finer the sound that can be reproduced.
“SILENT CINEMA”
“SILENT CINEMA” is an original Yamaha system that
reproduces in a pair of headphones the acoustic
personality of sound field programs based on multi-
speakers. Headphone parameters have been set for each
sound field so that natural stereoscopic sound can be
expressed and enjoyed through headphones.
S-Video Signal
With S-video the video signal that was normally
transmitted using a pin cable is separated and
transmitted as a luminance Y-signal and chrominance C-
signal through an S video cable. Connecting with an S
VIDEO jack you can enjoy recording and playback with
more beautiful images.
Title, Chapter (DVD Video)
DVD video lets you divide a disc in a big way by titles
or a small way by chapters. Each division is either called
a title number or a chapter number.
Track (CD/Video CD)
A CD or Video CD can be divided into a number of
segments (tracks). Each division is called a title number.
Virtual Cinema DSP (Digital Sound
Field Processor)
Reproduces a surround speaker sound field to let you
enjoy virtual Center and Surround L/R Speakers with
only two Front L/R Speakers.
