Glossary
■ 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.
■ YPAO (YAMAHA Parametric Room
Acoustic Optimizer)
YPAO is an original YAMAHA system that configures
speaker settings such as speaker balance (volume level of
each speaker), delay time of each channel, and crossover/
high cut frequency for the subwoofer automatically.
YPAO uses the supplied optimizer microphone to collect
and analyze sounds output from the speakers in the actual
listening environment.
■ Component video signal
With the component video signal system, the video signal
is separated into the Y signal for the luminance and the PB
and P
R 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.
■ Decoder
A device that converts encoded data on DVD and other
media back to its original audio or video signal.
■ Film and video data
In general, DVD media can be classified into the 2 types
below.
• Film Data
Video recorded at 24 frames/second. (The film used for
shooting movies is recorded at 24 frames/second.)
Recently 30 frames/second progressive video has made
its debut.
• Video Data
Video recorded at 30 frames/second.
CinemaStation will automatically recognize whether the
source recorded on DVD is film or video, then select the
best method to convert it into progressive output.
■ Interlace and progressive outputs
Up to now the standard video signal has been NTSC with
525i (i: interlaced) scan lines. In contrast, 525p
(p: progressive) is a high-density signal with double the
number of scan lines.
■ 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.
■ 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.
