Additional Information
Dynamic range
The difference between the quietest and loudest
sounds possible in an audio signal (without distorting
or getting lost in noise). Dolby Digital and DTS
soundtracks are capable of a very wide dynamic range,
delivering dramatic cinema-like effects.
MPEG audio
An audio format used on Video CDs and some DVD
discs. This unit can convert MPEG audio to PCM
format for wider compatibility with digital recorders
and AV amplifiers. See also
PCM
.
MPEG video
The video format used for Video CDs and DVDs. Video
CD uses the older MPEG-1 standard, while DVD uses
the newer and much better quality MPEG-2 standard.
Optical digital output
A jack that outputs digital audio in the form of light
pulses. Connect components with optical digital jacks
using a special optical cord, available from specialist
audio dealers.
PCM (Pulse Code Modulation)
The most common system of encoding digital audio,
found on CDs and DAT. Excellent quality, but requires
a lot of data compared to formats such as Dolby
Digital and MPEG audio. For compatibility with digital
audio recorders (CD, MD and DAT) and AV amplifiers
with digital inputs, this unit can convert Dolby Digital
and MPEG audio to PCM. See also
Digital audio
.
PBC (PlayBack Control) (Video CD only)
A system of navigating a Video CD through on-screen
menus recorded onto the disc. Especially good for
discs that you would normally not watch from
beginning to end all at once—karaoke discs, for
example.
Progressive scan video
Also called non-interlaced video, this method of
displaying a picture updates all the lines in one pass,
resulting in a more stable, flicker-free image than
interlaced video (for a given scanning rate).
PureCinema
Video on a DVD disc may be either video material
(originally shot on video) or film material (originally
shot on film). Video material has a frame rate of 30
frames/second, compared to 24 frames/second for
film. This recorder converts film material to 60 frames/
second (in progressive scan mode). PureCinema
adjusts the picture so that it matches more closely the
picture quality of a cinema screen
You can see whether video on a DVD disc is film or
video material by displaying the transfer rate. If a ‘#’
appears above the transfer rate display, it is film
material.
Regions (DVD only)
Regions associate discs and players with particular
areas of the world. This unit will only play discs that
have compatible region codes. You can find the region
code of your unit by looking on the rear panel. Some
discs are compatible with more than one region (or all
regions).
Sampling frequency
The rate at which sound is measured to be turned into
digital audio data. The higher the rate, the better the
sound quality, but the more digital information is
generated. Standard CD audio has a sampling
frequency of 44.1kHz, which means 44,100 samples
(measurements) per second. See also
Digital audio
.
Title (DVD only)
A collection of chapters on a DVD disc. See also
Chapter
.
Track
Audio CDs and Video CDs use tracks to divide up the
content of a disc. The DVD equivalent is called a
chapter. See also
Chapter
.
