EXPLANATION OF TERMS

Angle
Some DVD discs contain various scenes that
have been simultaneously shot from a num-
ber of different angles (the same scene is
shot from the front, from the right, from the
left and so on.) When viewing such discs and
pressing ANGLE button, you can view the
scene from different angles.
Chapter Number
Chapter numbers are recorded in a DVD. The
film is divided to many numbered chapters.
The required scene can be quickly found with
these numbers.
DVD Disk
This is a high-density optical disc which con-
tains digital signals and provides high quality
video and audio. Using a new video compres-
sion technology (MPEG II), as well as high-
density recording technology allows it to pro-
vide superlative viewing of continuous video
material recorded on DVD (for example, one
disc can contain the whole film). A DVD disc
consists of two glued thin substrates of 0.6
mm each. Because of the fact that the thin-
ner the disc, the higher is the data compres-
sion recorded on it, a DVD disc has more
capacity than a single thick disc of 1.2 mm.
Playback Control (PBC)
This function is recorded on VCD 2.0 discs.
The scenes or information to be viewed (or
listened to) can be selected interactively on
the TV screen using the menu.
Subtitles
Text representation of dialogs in a lower part
of the screen (should be recorded by DVD
recording software)
Playback Timer
Shows playback time passed from the begin-
ning of the disc of film. The function can be
used for quick search of a required scene
(does not work with some discs)

Title Number
These numbers are recorded in a DVD. If
there are several titles on the disc, they are
numbered as Title 1, Title 2 and so on.
Track Number
These numbers are assigned to tracks and
written on a VCD or CD. The required track
can be quickly found with these numbers.
Video CD
Contains both video and audio data. The VCD
quality corresponds to the video tape quality.
This player can also play VCD 2.0 discs with
PBC function.
SPDIF
SPDIF (Sony Philips Digital Interface Format).
Dolby Digital or DTS signals can be repro-
duced through optical or coaxial outputs
located on the DVD player rear panel. If you
want to connect DVD player via optical or
coaxial cord to some external device, for
example, to a mini-discs player, DAT, Prologic
amplifiers and so on, read the external device
instructions and select the appropriate set-
tings , RAW or PCM.

DISC HANDLING AND MAINTENANCE

Handling discs

not touch its surface, to avoid
leaving fingerprints on it.

with a ball-point pen and other
writing objects.
• Never use cleaning aerosols,
antistatic agents, benzene or solvents.
• Do not drop or bend the disc.
