On handling discs
 To keep the disc clean, handle the disc by its 
edge. Do not touch the surface.
 Do not stick paper or tape on the disc.
 Do not expose the disc to direct sunlight or 
heat sources such as hot air ducts, or leave it in 
a car parked in direct sunlight as the 
temperature may rise considerably inside the 
car.
 After playing, store the disc in its case.
On cleaning
 Before playing, clean the disc with a cleaning 
cloth.
Wipe the disc from the center out.
 Do not use solvents such as benzine, thinner, 
commercially available cleaners, or anti-static 
spray intended for vinyl LPs.
This system can only play back a standard 
circular disc. Using neither standard nor circular 
discs (e.g., card, heart, or star shape) may cause 
a malfunction.
Do not use a disc that has a commercially 
available accessory attached, such as a label or 
ring.If you experience any of the following 
difficulties while using the system, use this

 If the HDMI OUT jack is used for video output, 
changing the [HDMI RESOLUTION] setting in 
[SCREEN SETUP] may solve the problem 
(page 73). 
Connect the TV and the system using a video jack 
other than the HDMI OUT, and switch the TV’s 
input to the connected video input so that you can 
see the on-screen displays. Change the [HDMI 
RESOLUTION] setting in [SCREEN SETUP], 
and switch the TV’s input back to HDMI. If the 
picture still does not appear, repeat the steps and 
try other options.
 You have selected “PROGRESSIVE AUTO” or 
“PROGRESSIVE VIDEO” using the

 The disc is dirty or flawed.
 If the picture output from your system goes 
through your VCR to get to your TV, the copy-
protection signal applied to some DVD programs 
could affect picture quality. If you still experience 
problems even when you connect your system 
directly to your TV, try connecting your system to 
your TV’s S video input (page 21).
Even though you set the aspect ratio in [TV 
TYPE] of [SCREEN SETUP], the picture does 
not fill the screen.
 The aspect ratio on the disc is fixed.
Color irregularity occurs on the TV screen.

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.
Digital Cinema Auto Calibration
Digital Cinema Auto Calibration was developed 
by Sony to automatically measure and adjusts 
the speaker settings to your listening 
environment in a short period of time. 
Digital Direct Twin Drive Subwoofer
Utilizing Sonys proprietary S-Master 
technology, the Digital Direct Twin Drive 
Subwoofer features two S-Master Digital 
Amplifiers that provide dedicated power to a 
strategically located subwoofer for astounding 
sound performance. Easy to set up, Digital 
Direct Twin Drive Subwoofer provides a stable 
sound field over a much larger listening area 
without having to adjust frequency levels.
DivX®
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 soundfield 
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 Digital Theater Systems, 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 
Glossary

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 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.
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.
File
A JPEG image or a DivX video on a DATA CD/
DATA DVD. (“File” is an exclusive definition 
for this system.) A single file consists of a single 
image or movie.
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.
HDMI (high-definition multimedia 
interface)
HDMI is an interface that supports both video 
and audio on a single digital connection. The 
HDMI connection carries standard to high 
definition video signals and multi-channel audio 
signals to AV components such as HDMI 
equipped TVs, in digital form without 
degradation. Since the video signals are 
compatible with the current DVI (digital visual 
interface) format, HDMI jacks can be connected to DVI (digital visual interface) jacks by way of 
an HDMI -DVI (digital visual interface) 
converter cord. The HDMI specification 
supports HDCP (high-bandwidth digital 
contents protection), a copy protection 
technology that incorporates coding technology 
for digital video signals. 
Interlace format
(Interlaced scanning)
The Interlace format is the NTSC standard 
method for displaying TV images at 30 frames 
per second. Each frame is scanned twice - 
alternately between the even numbered scanning 
lines and then odd numbered scanning lines, at 
60 times per second.
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.
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.
Progressive format
(sequential scanning)
In contrast to the Interlace format, the 
progressive format can reproduce 50 - 60 frames 
per second by reproducing all scanning lines 
(525 lines for the NTSC system, 625 lines for the 
PAL system). The overall picture quality 
increases and still images, text and horizontal 
lines appear sharper. This format is compatible 
with the 525 or 625 progressive format.

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.”
Super Audio CD
Super Audio CD is a new high-quality audio 
disc standard where music is recorded in the 
DSD (Direct Stream Digital) format 
(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.
xTypes 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
1): A layer that is readable by a 
conventional CD playerA 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

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.
