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.
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.
In order to enjoy Dolby Digital discs, this unit’s digital
output jack (either coaxial or optical) must be connected
to the digital input jack of an AV amplifier with Dolby
Digital decoding capability or to a Dolby Digital decoder.
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, as
well as CDs. 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 or to a DTS decoder to be able to
enjoy the surround sound of DTS audio. 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.
Karaoke mode
This mode is used when you desire to enjoy Karaoke.
There is no digital output when using in the Karaoke
mode. Set to the Normal mode when desiring to enjoy
moviesor music.
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.
