Playback Control (PBC)
Signals encoded on VIDEO CDs (Version
2.0) to control playback.
By using menu screens recorded on VIDEO
CDs with PBC functions, you can enjoy
playing simple interactive programs,
programs with search functions, and so on.
Region Code
This receiver is used to protect copyrights. A
region number is allocated on each DVD
system or DVD disc according to the sales
region. Each region code is shown on the
receiver as well as on the disc packaging.
The receiver can play the discs that match its
region code. The receiver can also play discs
with the “
ALL
” mark. Even when the region
code is not shown on the DVD, the region
limit may still be activated.
Scene
On a VIDEO CD with PBC (playback
control) functions, the menu screens,
moving pictures and still pictures are
divided into sections called “scenes.”
Title
The longest sections of a picture or music
feature on a DVD, movie, etc., in video
software, or the entire album in audio
software.
Track
Sections of a picture or a music piece on a
Super Audio CD, CD, VIDEO 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 the worldwide standards 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 the 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 receiver conforms to both versions.
Super Audio CD
This audio format is based upon the current
audio CD standards but includes a greater
amount of information which provides
higher quality sound. There are three types
of discs: single layer, double layer and
hybrid discs. The hybrid disc contains both
standard audio CD and Super Audio CD
information.
