GLOSSARY

■ SILENT CINEMA

YAMAHA has developed a natural, realistic sound effect

DSP algorithm for headphones.

Parameters for headphones have been set for each sound

field so that accurate representations of all the sound field

programs can be enjoyed on headphones.

■ Virtual CINEMA DSP

YAMAHA has developed a Virtual CINEMA DSP

algorithm that allows you to enjoy DSP sound field

surround effects even without any surround speakers by

using virtual surround speakers.

It is even possible to enjoy Virtual CINEMA DSP using a

minimal two-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.

■ ITU-R

ITU-R is the radio communication sector of the ITU

(International Telecommunication Union). ITU-R

recommends a standard speaker placement which is used

in many critical listening rooms, especially for mastering

purposes.

■ Composite Video signal

With the composite video signal system, the video signal

is composed of three basic elements of a video picture;

color, brightness and synchronization data. A composite

video jack on a video component transmits these three

elements combined.

■ 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 P

and PR 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.
