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). See also
Interlaced video.
PureCinema
Video on a DVD discs 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/
sec., compared with 24 frames/sec. for film. This player
converts film material to 60 frames/sec. (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 video transmission rate.
If a hash mark (#) appears above the transmission rate
display, it is film material.
Regional restriction codes (region number)
Regional restriction codes are built in to DVD players and
DVD discs for each sales region. If the regional code of
the DVD player does not match one of the regional
codes of the DVD disc, playback is not possible.
The region number can be found on the rear panel of the
DVD player. The illustration below shows the regions
and corresponding region numbers.
Subtitle
Subtitles are language titles superimposed on movies, or
other media. Up to 32 different subtitle languages can be
recorded on a DVD disc. The subtitle function can be
used to select the language of your choice.
S-video
Connecting the S-video output on the player to a TV or
monitor with S-video input via an S-video cable produces
clearer picture reproduction by sending separate signals
for the luminance and the color. These signals are then
combined by the television to produce a better quality
picture.
TruSurround
TruSurround is a simulated surround system which
produces a surround sound effect from stereo speakers.
Virtual Dolby Digital
Virtual Dolby Digital uses Dolby Digital multichannel
audio sources to create a realistic surround sound effect
from stereo speakers.
