English 6 INTRODUCTION Introduction DVD Video Recorder DVD (Digital Versatile Disc) is the new storage medium that combines the convenience of the Compact Disc with the latest advanced digital video technology. DVD-Video uses state-of-the-art MPEG2 data com

18、pression technology to register an entire movie on a single 5-inch disc. DVDs variable bitrate compression, running at up to 9.8 Mbits/second, captures even the most complex pictures in their original quality. The crystal-clear digital pictures have a horizontal resolution of over 500 lines, with 72

19、0 pixels (picture elements) to each line. This resolution is more than double that of VHS, superior to Laser Disc, and entirely comparable with digital masters made in recording studios. DVD recording is the next step in video technology. DVD+ReWritable (DVD+RW) uses phase-change media, the same tec

20、hnology that formed the basis for CD- ReWritable. A high-power laser is used to change the reflectivity of the recording layer. This process can be repeated more than a thousand times. DVD+Recordable (DVD+R) uses discs based on an organic dye, a technology pioneered with the successful CD- Recordabl

21、e format, to produce discs that keep your data for a lifetime. Your Philips DVD recorder is a recorder and player for digital video discs, with a two-way compatibility to the universal DVD-Video standard. This means that: - existing pre-recorded DVD-Video discs can be played on your Philips DVD reco

22、rder and - recordings, made on your Philips DVD recorder, can be played on most DVD-Video players and DVD-ROM drives.
