MP3 (MPEG AUDIO Layer3 )
One of audio data compression methods adopted by MPEG.
The audio data can be compressed into approx. 1/10 with only
slight degradation of sound quality.
Multi-session
This means recording data onto a CD-R/CD-RW disc several
times. “Read-in/Program area/Read-out” of the data on a disc
makes one session.
If data, such as music is added onto a pre-recorded CD-R/RW
disc, a new session will be added. Such a disc is referred to as a
multisession disc.
Normal audio CD players can play back only the first session. On
the other hand, this unit can play back 2 or more sessions.
Optical digital audio output terminal
It converts the electrical signals into optical signals and transfers
them to an amplifier. The signals are free from noises caused by
external electrical effects.
Pan&Scan/Letterbox
In general, DVD-Video are produced with the intention that they be
viewed on a widescreen television with an aspect ratio of 16:9.
This means you can view most material with the intended aspect
ratio on a widescreen television.
Material with this ratio will not fit onto a standard television with an
aspect ratio of 4:3. Two styles of picture, “Pan&Scan” and “Letter-
box”, deal with this problem.
≥
Pan&Scan
The sides are cut off so the picture fills the
screen.
≥
Letterbox
A black belt appears on top and bottom of the
screen to present 16:9 aspect ratio video on the
4:3 aspect ratio screen.
Playback control (PBC)
If a Video CD has playback control, you can select scenes and
information with menus.
In this manual, playing back of the contents of a Video CD using
the menu screen is referred to as “Menu play” for Video CD.
Sampling frequency
This is the number of samples of sound taken per second during
conversion to a digital signal. A high sampling frequency results in
a sound close to the original when played back.
Title and chapter (DVD-Video)
The content of a DVD-Video is divided into larger segments (titles)
and smaller segments (chapters). They are identified by title
numbers and chapter numbers.
Track (Video CD/CD)
The content of a Video CD or CD is divided into some segments
(tracks) and they are identified by track numbers.
WMA (Windows Media Audio)
One of compression formats developed by Microsoft Corporation.
It achieves the same sound quality as MP3 with a file size that is
smaller than that of MP3.
