■
CD-R (compact disc recordable):
A type of
CD that can be recorded only once. Can be used to
make audio CDs, or MP3/WMA/JPEG discs.
■
CD-RW (compact disc rewritable):
A type of
CD that can be recorded many times. Can be used to
make audio CDs, MP3/WMA/JPEG discs.
■
Chapter:
Titles on DVD-Video discs can be subdi-
vided into chapters.
■
Component video:
A video connection format
that separates the luminance (Y) and color difference
signals (P
R
, P
B
), providing better picture quality than
S-Video.
■
Composite video:
A video connection format that
mixes the luminance and color signals together.
■
Dolby Digital:
The multi-channel digital surround
sound format used on most DVD-Videos.
■
Downmixing:
The process of mixing multiple
audio channels into fewer channels. For example, a
5.1-channel surround mix can be downmixed into
two channels for reproduction on stereo systems.
■
Downsampling:
The process of reducing the sam-
pling rate of digital audio.
■
DTS (Digital Theater System):
The 5.1-channel
surround format that uses less compression for faith-
ful reproduction.
■
DVD-R (DVD recordable):
A type of DVD disc
that can be recorded only once. Can be used to make
DVD-Video discs or to store computer data.
■
DVD-RW (DVD rewritable):
A type of DVD disc
that can be recorded many times. Can be used to
make DVD-Video discs or to store computer data.
■
DVD-Video:
The format for storing movies on
DVD, with interactive menus, multiple language
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.
■
Frame:
An individual TV picture is called a frame.
With the NTSC color system there are 30 frames per
second.
■
HD:
Abbreviation for high definition, as in
HDTV(high-definition TV).
■
HDCP (High-bandwidth Digital Content
Protection):
The video encryption technology
developed by Intel for HDMI/DVI. It’s designed to
protect video content and requires a HDCP-compati-
ble device to display the encrypted video.
■
HDMI (High Definition Multimedia Interface):
A new connection format that greatly simplifies AV
connections by carrying uncompressed SD or HD
digital video and digital audio all in one cable.
■
Interlaced scanning:
TV pictures are made by
scanning the screen in horizontal lines from top to
bottom. With Interlaced scanning, two scans (
fields
)
are used to make each picture (
frame
).
Contrast with
Progressive scanning.
■JPEG (Joint Photographic Experts Group):
The compressed file format used to store digital pho-
tos.
■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 Video
CDs.
■MPEG2 (Moving Picture Experts Group 2):
The compressed digital video format used for
DVD-Videos, 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
bottom. 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.
■Title: Movies on DVD-Video are called titles.
■WMA (Windows Media Audio): A compressed
file format for storing digital music.
