MPEG VIDEO
The video format used for Video CDs and DVDs. Video CD uses
the older MPEG-1 standard, while DVD uses the newer and
much better quality MPEG-2 standard.
Multi-angle function
Various angles, or viewpoints of the video camera, for a scene
are recorded on some DVDs
Multilingual function
Several languages for the sound or subtitles in a picture are
recorded on some DVDs.
Parental Control
A function of the DVD-Video to limit playback of the disc by the
age of the users according to the limitation level in each
country. The limitation varies from disc to disc; when it is
activated, playback is completely prohibited, violent scenes
are skipped or replaced with other scenes and so on.
PCM (Pulse Code Modulation)
The most common system of encoding digital audio, found on
CDs and DAT. Excellent quality, but requires a lot of data
compared to formats such as Dolby Digital and MPEG audio.
For compatibility with digital audio recorders (CD, MD and
DAT) and AV amplifiers with digital inputs, this unit can
convert Dolby Digital, DTS and MPEG audio to PCM.
PBC (PlayBack Control)
A system of navigating a Video CD through on-screen menus
recorded onto the disc.
PureCinema
Video on a DVD discs may be either video material (originally
shot on video) or film material (originally shot on film). Video
material has a frame rate of 30 frames/sec.(NTSC), compared
with 24 frames/sec. for film. This player converts film material
to 60 frames/sec. (in progressive scan mode). PureCinema
adjusts the picture so that it matches more closely the picture
quality of a cinema screen.
You can see whether video on a DVD disc is film or video
material by displaying the video transmission rate (see page
30). If # appears above the transmission rate display, it is film
material.
Regions
These associate discs and players with particular areas of the
world. This unit will only play discs that have compatible
region codes. You can find the region code of your unit by
looking on the rear panel. Some discs are compatible with
more than one region (or all regions).
Sampling frequency
The rate at which sound is measured to be turned into digital
audio data. The higher the rate, the better the sound quality,
but the more digital information is generated. Standard CD
audio has a sampling frequency of 44.1kHz, which means
44,100 samples (measurements) per second.
Slideshow
A feature of some DVD discs in which still pictures recorded
on the disc cycle automatically as the audio is played.
Title
The longest sections of a picture or a music piece on a DVD-
Video; a movie, etc., for a picture piece on video software; or
an album, etc., for a music piece on an audio software disc.
Each title is assigned a title number enabling you to locate the
title you want.
Track
Sections of a picture or a music piece on a CD, SACD, DVD-
Audio or Video CD. Each track is assigned a track number
enabling you to locate the track you want.
Video CD
A compact disc that contains moving pictures.
The picture data uses the MPEG 1 format, one of the
worldwide standards of digital compression technology.
The picture data is compressed to about 1/140 of its original
size. Consequently, a 12 cm Video Disc can contain up to 74
minutes of moving pictures.
Video CDs also contain compact audio data. Sounds outside
the range of human hearing are compressed while the sounds
we can hear are not compressed. Video CDs can hold 6 times
the audio information of conventional audio CDs.
There are 2 versions of Video CDs, and this system conforms
to both versions.
• Version 1.1: You can play only moving pictures and sounds.
• Version 2.0: You can play high-resolution still pictures and
enjoy PBC functions.
