480p
– Also known as 480 progressive, this is a form of standard-
definition digital television (SDTV) which is similar to VGA computer
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 com-
prised 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 pixels.
1080p
– Known also as full HD or Complete High Definition, 1080p
usually has a widescreen aspect ration of 16:9, which means a hori-
zontal resolution of 1920 pixels. The “p” stands for “progressive
scan”.
AVI
(Audio Video Interleave) – A file format that can contain audio/
video compressed standards using different combinations of codecs
(e.g. DivX® video file and a WMA audio file).
DivX®
– A video co-
dec 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 Rugged HD. DivX® movies offer bet-
ter compression and higher quality than standard MPEG movies.
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 computer
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 trans-
mission and reception of TV broadcasts in the United States. An
NTSC image has 525 horizontal lines per frame, which are inter-
laced 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 stan-
dard.
VOB (Video Objects)
– The format in which DVD movies are stored.
Within each VOB file, a number of video/audio/subpicture 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 Mi-
crosoft® 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 LaCinema
Rugged HD.
