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). With the addition of an optional, digital audio

processor (PXA-H900/PXA-H510/PXA-H700, etc.), you can recreate

the power and presence of a movie theater with Dolby Digital 5.1-

channel Surround.

In addition, DVDs offer a variety of functions.

Multiple audio* (page 24)

Movies can be recorded in up to eight languages. The desired

language can be selected from the unit.

Subtitles function* (page 24)

Movies can include subtitles in up to 32 languages. The desired

subtitle language can be selected from the unit.

Multi angle function* (page 23)

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.
