When the self-diagnosis function is activated to 
prevent the system from malfunctioning, a 5-
character service number (e.g., C 13 50) with a 
combination of a letter and 4 digits appears on 
the TV screen or front panel display. In this case, 
check the following table.
When displaying the version 
number on the TV screen
When you turn on the system, the version 
number [VER.X.XX] (X is a number) may 
appear on the TV screen. Although this is not a 
malfunction and for Sony service use only, 
normal system operation will not be possible. 
Turn off the system, and then turn on the system 
again to operate.

Album
Section of a music piece or an image on a data 
CD containing MP3 audio tracks or JPEG files.
Chapter
Subdivision of a title on a DVD. A title is 
composed of several chapters.
DivX® (except for United Kingdom 
and North American models)
Digital video technology created by DivX, Inc. 
Videos encoded with DivX technology are 
among the highest quality with a relatively small 
file size.
Dolby Digital
This movie theater sound format is more 
advanced than Dolby Surround Pro Logic. In 
this format, the surround 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” with the subwoofer channel 
designed as the 0.1 channel (since it functions 
only when a deep bass effect is needed). All six 
channels in this format are recorded separately 
for superior channel separation. Furthermore, 
since all the signals are processed digitally, less 
signal degradation occurs.
Dolby Pro Logic II 
Dolby Pro Logic II creates five full-bandwidth 
output channels from 2 channel sources. This is 
done using an advanced, high-purity matrix 
surround decoder that extracts the spatial 
properties of the original recording without 
adding any new sounds or tonal colorations.
xMovie mode
The Movie mode is for use with stereo television 
shows and all programs encoded in Dolby 
Surround. The result is enhanced sound field 
directionality that approaches the quality of 
discrete 5.1-channel sound.
xMusic mode
The Music mode is for use with any stereo music 
recordings, and provides a wide and deep sound 
space.
Dolby Surround Pro Logic
As one method of decoding Dolby Surround, 
Dolby Surround Pro Logic produces four 
channels from 2 channel sound. Compared with 
the former Dolby Surround system, Dolby 
Surround Pro Logic reproduces left-to-right 
panning more naturally and localizes sounds 
more precisely. To take full advantage of Dolby 
Surround Pro Logic, you should have one pair of 
surround speakers and a center speaker. The 
surround speakers output monaural sound.
DTS
Digital audio compression technology 
developed by DTS, Inc. This technology 
conforms to 5.1-channel surround. This format 
comprises of stereo rear channel and there is 
discrete subwoofer channel in this format. DTS 
provides the same 5.1 discrete channels of high 
quality digital audio. The good channel 
separation is realized due to the all channel data 
being recorded discretely and processed in 
digitally.
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 
a worldwide standard 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 
processes allocated data 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 
realistic audio presence.
Furthermore, various advanced functions such 
as the multi-angle, multilingual, and Parental 
Control functions are provided with the DVD.

DVD+RW
A DVD+RW (plus RW) is a recordable and 
rewritable disc. DVD+RWs use a recording 
format that is comparable to the DVD VIDEO 
format.
DVD-RW
A DVD-RW is a recordable and rewritable disc 
that is the same size as a DVD VIDEO. The 
DVD-RW has two different modes: VR mode 
and Video mode. DVD-RWs created in Video 
mode have the same format as a DVD VIDEO, 
while discs created in VR (Video Recording) 
mode allow the contents to be programmed or 
edited.
File
A JPEG image or a DivX video* recorded on a 
DATA CD/DATA DVD. (“File” is an exclusive 
definition for this system.) A single file consists 
of a single image or movie.
* Except for United Kingdom and North American 
models.
Film based software, Video based 
software
DVDs can be classified as Film based or Video 
based software. Film based DVDs contain the 
same images (24 frames per second) that are 
shown at movie theaters. Video based DVDs, 
such as television dramas or sit-coms, displays 
images at 30 frames (or 60 fields) per second.
MPEG audio
A coding system to compress digital audio 
signals. MPEG-1 is used for MP3 (MPEG-1 
Audio Layer-3). MPEG-2 is used for one of the 
audio format of DVD.
Multi-angle function
Various angles of a scene, or viewpoints of the 
video camera 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.
PCM (Pulse Code Modulation)
A method for converting analog audio to digital 
audio. It is used for the Compact Disc (CD) 
audio format.
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 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 discs 
that match its region code. The system can also 
play discs with the “ ” mark. Even when the 
region code is not shown on the DVD, the region 
limit may still apply.
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 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, 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 six times the 
audio information of conventional audio CDs.
There are two 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.
