Aspect ratio
Aspect ratio refers to the length to height ratio of TV
screens. The ratio of a standard TV is 4:3, while the ratio
of a high-definition or wide TV is 16:9. The latter allows
you to enjoy a picture with a wider perspective.
Bonus Group (DVD-Audio only)
Some DVD Audio discs have a group which is known as
the "Bonus Group" that can be accessed by inputting a 4-
digit key number. When attempting to play a Bonus
Group, the key number input screen is automatically
displayed. Playback begins once the key number has
been input. Additionally, you can set the key number
using the Setup screen General menu beforehand.
Browsable pictures (DVD-Audio only)
A feature of some DVD-Audio discs in which the user
can browse still pictures recorded on the disc as the
audio is played. See also Slideshow.
Chapter number
Chapter numbers are the numbers assigned to sections
of a title on the disc, similar to chapters in a book. If the
disc includes chapter numbers, you can locate the
section you want very quickly using search and other
functions.
Component (color difference) video output
The color signal of the TV is divided into the luminance
(Y) signal and the color (P and P
B
output. In this way mutual interference of each signal is
avoided. On a TV with component input jacks, these
signals are synthesized to produce the picture.
Condition memory
"Condition" refers to the various mode settings, etc. On
this player, various conditions, such as those set during
playback, can be memorized. This function allows you to
play back the same disc at any time without having to
redo your preferred settings.
Digital bitstream
The bitstream does not refer to the audio signal, but
rather to the digital data that, once converted, becomes
the audio signal. The player outputs digital bitstreams via
the digital optical or digital coaxial output. If the
bitstream cannot be decoded by the connected AV
amplifier etc., digital noise is produced. Digital bitstream
formats compatible with different entertainment
systems can be selected in the Setup screen Audio 1
menu.
Digital output (Coaxial)
Output of the digital audio signal is transmitted
electronically using a coaxial cable. Because the signal
being transmitted is digital, connection must be made to
the coaxial digital input of another component. Noise will
be output if connected to the analog audio inputs as the
digital signal cannot be decoded.

Digital output (Optical)
Normally, audio is converted to an electric signal and
transmitted through an electric wire from the player to
the amplifier, etc. Changing this signal to a digital signal
and transmitting it through an fiber-optic cable is called
optical digital output. Similarly, optical digital input
receives digital signals from external units such as an AV
amplifier or receiver.
DNR (Digital Noise Reduction)
Digital noise reduction, in reference to video picture
quality, refers to the detection and removal of digital
artifacts, or errant video data, which appear as specks
on the screen. When the digital noise reduction function
of this player is on, some of this data can be detected
and kept from appearing on the screen.
Dolby Digital
Using a maximum of 5.1 channels of audio, this high
quality surround system is used in many of the finer
movie theaters around the world.
1
DTS
DTS stands for Digital Theater System. DTS is a
surround system different from Dolby Digital that has
become a popular surround sound format for movies.
Dynamic range
Dynamic range refers to the difference between the
maximum and minimum levels of the audio soundtrack
as measured in decibels (dB).
Compressing the dynamic range raises the minimum
signal level and lowers the maximum signal level. This
allows you to hear voices and other low level audio
signals clearly while lowering strong audio signals like
the sound of explosions.
Group (DVD-Audio only)
A collection of tracks on a DVD-Audio disc. Equivalent to
a DVD-Video title. See also Title and Track.
Interlace scan
With interlace scan, the screen presentation is divided
into odd and even scan lines. The first presentation
(field) presents half of the screen . Before this image
has faded from the screen, the other half of the
presentation (frame) is displayed. The majority of TVs
and monitors manufactured until recently have relied on
the interlace scan system. In these operating
instructions, the amount of interlace scan resolution is
referred to followed by the letter "i" (for example, 525i).
