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-H701, 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 25)

Movies can include subtitles in up to 32 languages. The desired subtitle language can be selected from the unit.

Multi angle function* (page 24)

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.

Terminology

Dolby Digital

Dolby Digital is a digital audio compression technology developed by Dolby Laboratories that allows large quantities of audio data to be efficiently recorded on discs. It is compatible with audio signals from mono (1 channel) all the way up to 5.1- channel surround sound. The signals for the different channels are completely independent, and since the sound is high quality digital there is no loss of sound quality.

*The separately sold digital audio processor (PXA-H701, etc.) is required to enjoy full 5.1-channel surround sound.

The IVA-W205R/IVA-W202R performs Dolby Digital decoding when it outputs analogue audio signals, it just happens to be 2-channel audio not 5.1-channel.
