(conventional CDs are recorded in the PCM
format). The DSD format, using a sampling
frequency 64 times higher than that of a
conventional CD, and with 1-bit quantization,
achieves both a wide frequency range and a wide
dynamic range across the audible frequency
range, and so provides music reproduction
extremely faithful to the original sound.
x Types of Super Audio CDs
There are two types of discs, depending on the
Super Audio CD layer and CD layer
combination.
• Super Audio CD layer: A high-density
signal layer for Super Audio CD
•CD layer

conventional CD player
A Super Audio CD layer consists of the 2
channel area or the multi-channel area.
• 2 channel area: An area in which 2 channel
stereo tracks are recorded
• Multi-channel area: An area in which multi-
channel (up to 5.1 channels) tracks are
recorded

player.

to turn the disc over.

Title
The longest section of a picture or music feature
on a DVD, movie, etc., in video software, or the
entire album in audio software.
Track
Section of a picture or a music piece on a
VIDEO CD, CD, Super Audio CD, or MP3. An
album is composed of several tracks (MP3
only).
VIDEO CD
A compact disc that contains moving pictures.
The picture data uses the MPEG 1 format, one of
a worldwide standard of digital compression
technology. The picture data is compressed to
about 1/140 of its original size. Consequently, a
12 cm VIDEO CD can contain up to 74 minutes
of moving pictures.
VIDEO CDs also contain compact audio data.
Sounds outside the range of human hearing are
compressed while sounds we can hear are not
compressed. VIDEO CDs can hold 6 times the
audio information of conventional audio CDs.
There are 2 versions of VIDEO CDs.
• Version 1.1: You can play only moving
pictures and sounds.
• Version 2.0: You can play high-resolution still
pictures and enjoy PBC functions.
This system conforms to both versions.
