■ Virtual CINEMA DSP
YAMAHA has developed a virtual CINEMA DSP
algorithm that allows you to enjoy DSP sound field
surround effects even without any rear speakers by using
virtual rear speakers.
It is even possible to enjoy virtual CINEMA DSP using a
minimal 2-speaker system that does not include a center
speaker.
■ PCM (Linear PCM)
Linear PCM is a signal format under which an analog
audio signal is digitized, recorded and transmitted without
using any compression. This is used as a method of
recording CDs and DVD audio. The PCM system uses a
technique for sampling the size of the analog signal per
very small unit of time. Standing for “pulse code
modulation”, the analog signal is encoded as pulses and
then modulated for recording.
■ Sampling frequency and number
of quantized bits
When digitizing an analog audio signal, 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 number of quantized bits.
The range of rates that can be played back is determined
based on the sampling rate, while the dynamic range
representing the sound level difference is determined by
the number of quantized bits. In principle, the higher the
sampling frequency, the wider the range of frequencies
that can be played back, and the higher the number of
quantized bits, the more finely the sound level can be
reproduced.
■ S-video signal
With the S-video signal system, the video signal normally
transmitted using a pin cable is separated and transmitted
as the Y signal for the luminance and the C signal for the
chrominance through the S-video cable. Using the S
VIDEO jack eliminates video signal transmission loss and
allows recording and playback of even more beautiful
images.
■ Component video signal
With the component video signal system, the video signal
is separated into the Y signal for the luminance and the

signals for the chrominance. Color can
be reproduced more faithfully with this system because
each of these signals is independent. The component
signal is also called the “color difference signal” because
the luminance signal is subtracted from the color signal.
A monitor with component input jacks is required in
order to use the component signal for output.
