■
DVD-RW (DVD rewritable):
A type of DVD disc
that can be recorded over and over again. Can be used for
DVD-Video or DVD-Audio.
■
DVD-Video:
The format for storing MPEG2 video
on DVD, with interactive menus, multiple soundtracks,
subtitles, camera angles, and so on.
■
Field:
In interlaced scanning, a field is a single scan
of the screen. There are two fields per frame.
See
Inter-
laced Scanning
and
Progressive Scanning.
■
Frame:
An individual TV picture is called a frame.
With the NTSC color system there are 30 frames per sec-
ond.
■
Interlaced scanning:
TV pictures are made by
scanning the screen in horizontal lines from top to bot-
tom. With Interlaced scanning, two scans (
fields
) are
used to make each picture (
frame
).
Contrast with
Pro-
gressive scanning.
■
JPEG (Joint Photographic Experts Group):
The acronym commonly used to refer to the compressed
file format used to store digital images.
■
LFE (low-frequency effects):
The surround-
sound channel used for low-frequency effects.
■
Linear PCM:
The uncompressed digital audio for-
mat used for audio CDs. PCM stands for
Pulse Code
Modulation.
■
MP3 (MPEG 1 Audio Layer 3):
Popular com-
pressed file format for storing digital music.
■
MPEG1 (Moving Picture Experts Group 1):
The compressed digital video format used for VCDs.
■
MPEG2 (Moving Picture Experts Group 2):
The compressed digital video format used for DVDs,
offering better picture quality than MPEG1.
■
NTSC:
The color TV system used in the United
States, Japan, Taiwan, and Korea.
■
PAL:
The color TV system used in most of Europe,
the United Kingdom, Australia, Brazil, and China.
■

■
Progressive scanning:
TV pictures are made by
scanning the screen in horizontal lines from top to bot-
tom. With progressive scanning, each picture (
frame
) is
made by scanning the entire screen in one go, resulting
is a clearer and stabler picture.
Contrast with
Interlaced
scanning.
■
S-Video:
A video connection format that separates
the luminance (Y) and color (C) signals, providing better
picture quality than composite video.
■
SACD (Super Audio CD):
SACD uses Direct
Stream Digital (DSD) technology for audio performance
superior to that of standard CDs. It also supports multi-
channel audio, and hybrid discs can be played in stan-
dard CD players.
■
Title:
The contents of DVD-Video discs are orga-
nized into titles.
■
VCD (Video CD):
The format for storing MPEG1
video on CD.
■
VLSC (Vector Linear Shaping Circuitry):
Unique Onkyo circuitry that reduces pulse noise in ana-
log audio signals converted from digital sources.
