Information 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. CDs 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-H900, PXA-H701, etc.) is required to enjoy full 5.1-channel surround sound. The DVA-9861 performs Dolby Digital decoding when it outputs analog audio signals; 2-channel audio, not 5.1-channel. Minimum pit length - 0.9 µm 1.2 mm DVDs Minimum pit length - 0.9 µm 0.6 mm 0.6 mm Track pitch 1.6 µm Track pitch 0.74 µm Center speaker Front speakers Rear speakers 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-H701, etc.), you can recreate the power and presence of a movie theatre with Dolby Digital 5.1-channel Surround. In addition, DVDs offer a variety of functions. • Multiple audio* (page 19) Movies can be recorded in up to eight languages. The desired language can be selected from the remote control. • Subtitles function* (page 19) Movies can include subtitles in up to 32 languages. The desired subtitle language can be selected from the remote control. • Multi angle function* (page 19) When the DVD contains a movie shot from multiple angles, the desired angle can be selected from the remote control. • 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. Subwoofer Speaker layout for enjoying Dolby Digital sound/dts sound DTS This is a home-use digital sound format of the DTS Sound System. This is a high quality sound system, developed by Digital Theater Systems, Inc. for use in movie theaters. DTS has six independent sound tracks. The theatre presentation is fully realized in the home, etc. DTS is the abbreviation for Digital Theater System. * To enjoy DTS surround sound you need the separately sold DTS digital audio processor (PXA-H900, PXA-H701, etc.).
