480p
– Also known as 480 progressive, this is a form of standard-
definition digital television (SDTV) which is similar to VGA com-
puter displays. A DVD’s resolution is 480p, but this resolution can
only be seen when the DVD player outputs a progressive-scan
signal, and the television has progressive-scan or component-
video inputs.
720p
– Also known as 720 progressive, this is one of two formats
designated as a high-definition digital television (HDTV), ATSC
DTV standard. This technology uses progressive scanning and is
comprised of 720 vertical pixels by 1,280 horizontal pixels.
1080i
– Also known as 1080 interlaced, this is the second of two
formats designated as a high-definition digital television (HDTV),
ATSC DTV standard. This technology uses interlaced scanning
and is comprised of 1,080 vertical pixels by 1,920 horizontal pix-
els.
AVI
(Audio Video Interleave) – A file format that can contain au-
dio/video compressed standards using different combinations of
codecs (e.g. DivX® video file and a WMA audio file).
DivX®
–
A video codec developed from the new MPEG-4 compression
standard, which allows for compression/decompression of videos
into a specified format. The DivX® codec can play movies using
any DivX®-enabled player, such as the LaCinema Classic Bridge.
DivX® movies offer better compression and higher quality than
standard MPEG movies.
Dolby Digital
– Dolby Digital lets you experience 5.1-channel
surround sound while supporting monaural (single channel) and
stereo (two-channel) setups. In a 5.1-channel environment, there
are five discrete full-range channels—Left, Center, Right, Left Sur-
round, and Right Surround—plus a sixth channel for low-frequen-
cy effects.
DTS
– Digital sound technology, which provides the technology
for virtually all movie soundtracks.
Firmware
– Permanent or semi-permanent instructions and data
programmed directly into the circuitry of a programmable read-
only memory or an electronically-erasable, programmable read-
only memory chip. Used for controlling the operation of the com-
puter or tape drive. Distinct from the software, which is stored in
random access memory and can be altered.
ID3 Tag
– An embedded tag in MP3 files that communicates a
song’s title, artist and album. These tags can be edited.
MPEG (Motion Picture Experts Group)
– These are the developers
of the MPEG-1 (VideoCDs), MPEG-2 (DVDs and SuperVCDs) and
MPEG-4 (DivX®, WMV) video compression standards. The MPEG
group is also responsible for the development of the MP3 and
AAC audio compression standards.
NTSC (National Television Standards Committee)
– This group
is responsible for the development of a set of protocols used for
transmission and reception of TV broadcasts in the United States.
An NTSC image has 525 horizontal lines per frame, which are
interlaced from left to right, top to bottom. NTSC signals are not
directly compatible with computer systems.
PAL (Phase Alternation Line)
– This is the analog TV display com-
monly used in Europe. The PAL image has 625 horizontal lines
per frame, and the color definition differs slightly from the NTSC
standard.
VOB (Video Objects)
– The format in which DVD movies are
stored. Within each VOB file, a number of video/audio/subpic-
ture streams are stored. Subpicture streams refer to the subtitles
on DVDs and other VOB files. These subtitles are video streams
that overlay the main picture stream, and can be turned on or off.
WMA (Windows Media Audio)
– An audio format developed by
Microsoft® for audio streaming and compression.
XviD
– A video codec, very similar to DivX®, based on the MPEG-
4 compression standard. This an open-source video codec that is
currently being developed around the world. The XviD codec can
play movies using any XviD-enabled player, such as the LaCin-
ema Classic Bridge.
