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.
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
B
and P
R
) signals and then
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.
Dolby Digital
The maximum 5.1 channels of audio used in the
surround system (Surround Digital) for movie theaters is
digital data compressed by the third generation algorithm
encoder, AC-3.
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. In
order to enjoy the benefits of DTS encoded discs, the
digital output jack (either coaxial or optical) of this player
needs to be connected to an AV amplifier or receiver
with DTS decoding capability or to a DTS decoder. DTS
audio is not output from the analog audio outputs.
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.
MPEG
Short for Moving Picture Experts Group. This is an
international standard for compression of moving
images. On some DVDs, digital audio has been
compressed and recorded in this format.
Multi-angle
When you watch a TV program, you are watching the
image filmed through the TV camera. Because of this,
the picture is displayed on your TV from the viewpoint of
the TV camera’s position. In a TV studio, the image is
filmed by many cameras at the same time, and one of
those images is selected by the program director and
transmitted to your TV. If all the filmed images were
transmitted to your TV you would be able to select the
camera image you want. Some DVD discs are recorded
with the angles of more than one camera used for
filming, and these can be selected using this player.
These types of discs are called multi-angle discs.
