Glossary
Bit rate
Value indicating the amount of video data
compressed in a DVD per second. The unit
is Mbps (Mega bit per second). 1 Mbps
indicates that the data per second is
1,000,000 bits. The higher the bit rate is, the
larger the amount of data. However, this
does not always mean that you can get
higher quality pictures.
Chapter
Sections of a picture or a music piece on a
DVD that are smaller than titles. A title is
composed of several chapters. Each chapter
is assigned a chapter number enabling you
to locate the chapter you want.
Digital Cinema Sound (DCS)
This is the generic name of the surround
sound produced by digital signal processing
technology developed by Sony. Unlike
previous surround sound fields mainly
directed at the reproduction of music,
Digital Cinema Sound is designed
specifically for the enjoyment of movies.
Dolby Digital
This sound format for movie theaters is
more advanced than Dolby Pro Logic
Surround. In this format, the rear speakers
output stereo sound with an expanded
frequency range and a subwoofer channel
for deep bass is independently provided.
This format is also called “5.1” because the
subwoofer channel is counted as 0.1 channel
(since it functions only when a deep bass
effect is needed). All six channels in this
format are recorded separately to realize
superior channel separation. Furthermore,
since all the signals are processed digitally,
less signal degradation occurs.
Self-diagnosis Function
(When letters/numbers appear in the
display)
The self-diagnosis function is activated to
prevent the system from malfunctioning. In
this case a five-character service number
(e.g., C 13 00) with a combination of a letter
and digits appears on the screen and the
front panel display. Refer to the following
table.
First three
characters of
the service
number
C 13
C 31
E XX
(xx is a number)
Cause and/or Corrective
Action
The disc is dirty.
,Clean the disc with a soft
cloth (page 9).
The disc is not inserted
correctly.
,Re-insert the disc
correctly.
To prevent a malfunction, the
system has performed the self-
diagnosis function.
,Contact your nearest Sony
dealer or local authorized
Sony service facility and
give the 5-character
service number.
Example: E 61 10
C:13:00

Dolby Pro Logic Surround
As one method of decoding Dolby
Surround, Dolby Pro Logic Surround
produces four channels from two-channel
sound. Compared with the former Dolby
Surround system, Dolby Pro Logic Surround
reproduces left-to-right panning more
naturally and localizes sounds more
precisely. To take full advantage of Dolby
Pro Logic Surround, you should have one
pair of rear speakers and a centre speaker.
The rear speakers output monaural sound.
DTS
Digital audio compression technology that
the Digital Theater Systems, Inc. developed.
This technology conforms to 5.1-channel
surround. The rear channel is stereo and
there is discrete subwoofer channel in this
format. DTS provides the same 5.1 discrete
channels of high quality digital audio. It
superior channel separation is realized
because all the channel data is recorded
discrete and processed in digital.
DVD
A disc that contains up to 8 hours of moving
pictures even though its diameter is the same
as a CD.
The data capacity of a single-layer and
single-sided DVD, at 4.7 GB (Giga Byte), is
7 times that of a CD. Furthermore, the data
capacity of a dual-layer and single-sided
DVD is 8.5 GB, a single-layer and double-
sided DVD 9.4 GB, and a dual-layer and
double-sided DVD 17 GB.
The picture data uses the MPEG 2 format,
one of the worldwide standards of digital
compression technology. The picture data is
compressed to about 1/40 of its original size.
The DVD also uses the variable rate coding
technology that changes the data to be
allocated according to the status of the
picture.The audio data is recorded in Dolby Digital
as well as in PCM, allowing you to enjoy
more real audio presence.
Furthermore, various advanced functions
such as the multi-angle, multilingual, and
Parental Control functions are provided with
the DVD.
Multi-angle function
Various angles, or viewpoints of the video
camera for a scene are recorded on some
DVDs.
Multilingual function
Several languages for the sound or subtitles
in a picture are recorded on some DVDs.
Parental Control
A function of the DVD to limit playback of
the disc by the age of the users according to
the limitation level in each country. The
limitation varies from disc to disc; when it is
activated, playback is completely prohibited,
violent scenes are skipped or replaced with
other scenes and so on.
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, etc.
Region Code
This system 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
system as well as on the disc packaging. The
system can play the discs that match its
region code. The system 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.

Additional Information
Title
The longest section of a picture or music
feature on DVD, music, etc., in Video
software, or the entire album in audio
software. Each title is assigned a title
number enabling you to locate the title you
want.
Track
Sections of a picture or a music piece on a
CD or VIDEO CD. Each track is assigned a
track number enabling you to locate the
track you want.
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 system 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.
