About DVDs
Music CDs and DVDs have grooves (tracks) in which the digital
data is recorded. The data is represented as microscopic pits
recorded into the track – these pits are read by a laser beam to
play the disc. On DVDs, the density of the tracks and pits is
twice that of CDs, so DVDs can contain more data in less space.
A 12 cm disc can contain one movie or about four hours of
music.
In addition, DVDs provide sharp picture quality with vivid colors thanks
to a horizontal resolution of over 500 lines (compared to less than 300
for VHS tape).
In addition, DVDs offer a variety of functions.
Multiple audio* (page 25)
Movies can be recorded in up to eight languages. The desired
language can be selected from the unit.
Subtitles function* (page 25)
Movies can include subtitles in up to 32 languages. The desired
subtitle language can be selected from the unit.
Multi angle function* (page 25)
When the DVD contains a movie shot from multiple angles, the
desired angle can be selected from the unit.
Multi story function*
With this function, a single movie includes various story lines.
You can select different story lines to view various versions of the
same movie.
Operation differs from disc to disc. Story line selection screens
including instructions appear during the movie. Just follow the
instructions.
* The functions audio languages, subtitle languages, angles, etc., differ
from disc to disc. For details, refer to the disc’s instructions.
