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 colours 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
*
Movies can be recorded in up to eight languages. The desired
language can be selected from the unit.
Subtitles function
*
Movies can include subtitles in up to 32 languages. The desired
subtitle language can be selected from the unit.
Multi angle function
*
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.
* These functions differ from disc to disc. For details, refer to the disc’s
instructions.
