35、r TV, you always see it the way it was meant to be. Digital video DVD-Video uses state-of-the-art MPEG2 data compression technology to reg- ister 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

36、their original quality. The crystal-clear digital pictures have a horizontal resolution of over 500 lines, with 720 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.

37、 DVD-Video discs conform to either the PAL or NTSC video standard. This player can play both PAL and NTSC discs, presenting them in the best possible way on your multi-standard TV screen. As the universal video system of the future, DVD-Video offers optimal pictures on any TV screen. Introduction Yo

38、ur Philips DVD-Video player will play digital video discs conforming to the universal DVD-Video standard. With it, you will be able to enjoy full- length movies with true cinema picture quality, as well as stereo or multi-channel sound (depending on the disc and your playback setup). The unique feat

39、ures of DVD-Video, such as selection of sound track, subtitle languages and different camera angles (again depending on the disc), are all in- cluded.
