.mpeg - Stands for Moving
Picture Experts Group. MPEG (pronounced M-peg) is the name of a
family of standards used for coding audio-visual information (e.g.,

advantage of MPEG compared to other video and audio coding formats is
that MPEG uses very sophisticated compression techniques to create
files that are much smaller for the same quality. MPEG-1: “postage

connect to the host. A computer or program requests a service of
another computer or program.
34. Client/Server
- set of computer applications (programs) in which two or more
computers work together. Server(s) store data and programs, which
they deliver on request to clients. Part of the processing is done on
the client, while the server concentrates on storing and delivering
the data to be processed. This interaction between the client and
server occurs in the background, so users are typically unaware which
computer handles what.
35. CODEC

decompressing data.
36.
Color Palette - a selection
of available colors; ranging from 16 colors to 16.7 million
37.
Compression
- Process for reducing file size, often called "zipping" or
"archiving". The resulting, compressed file can be from a
single, large file or can contain several files that have been
squeezed into a single file. The many-to-one compression makes file
group identification, copying, and transporting faster and
easier.
38. Cookie
- A "cookie" is a small piece of information, a virtual
"sticky note", sent by a Web server to be stored, by your
browser, on your hard drive. The cookie stores information about you
and can be retrieved by the Website each time you visit there.
Without them, sites would not be able to retain information about
individual visits; thus, cookies store "state information."
39.
Digital
- not physical, exists in a digital world; soft copy; something that
exists only in the computer—not physical; process of converting
video or audio signals, normally in waveform, into 1's and 0's. This
digital format (actually patterns of on's/high-voltage (1's) and
off's/low voltage (0's) rather than digits) can be processed by a
computer
40. Dithering
- blending colors to modify colors or produce new ones.
41.
Downlink - transmission of
a signal from a satellite to a receiver on Earth.
42. Download -
process of transferring a file from system to another.
42b.
Dropped Frames
- In digital video, when the computer cannot keep pace with the
displayed images, it drops frames in an attempt to catch up.
43.
DVD
- a new standard for recording video on CD-ROM's using MPEG2, thus
boasting better-than-broadcast TV quality. Costing about the same as
a CD, DVD-ROM's hold 8 to 40 times more data.
44.
Frame - one image in a
sequence of images; one image out of many in a sequence; a single
picture in a computerized "movie"
45. Frame

second displayed in a stream of video.
46.
FPS – Stands for
Frames Per Second. number of frames that play per second; speed at
which you watch a movie; frames per second - the number of picture
images displayed per second, giving digital video the illusion of
motion. 30 fps considered to be TV quality
47. Full-motion
video - digital video
running at 30 fps; Full-motion video, with no dropped frames, is
considered 30 fps; 30 fps (see above) is considered full-motion,
television-quality video.
48. Graphics
- Images are typically vector (object-oriented) or bitmap
(rastor).
49. Graphics,
bitmap - images are laid
out in pixels, much like dots of paint on a canvas. As such, bitmap
objects are not independent entities, which can be singled out for
manipulation, but patterned series of dots. To enlarge (or reduce)
bitmap images, the number of pixels is increased (decreased), often
giving the resulting image a jagged appearance. File formats include:
GIF, PCX, TIF, BMP, JPG.
50. Graphics,
vector - Graphics
consisting of objects, each of which can be separately manipulated -
e.g. sized, moved, (un)grouped, positioned to the back/front. The
graphic components are calculated, hence can be sized without
distortion. File formats include: EPS, PIC, DRW, WMF.
51.
Graphical User Interface
(GUI) - A computer
interface using point-and-click mouse actions (rather than the
keyboard exclusively) and pictures (rather than text exclusively).
Windows, Macintosh, Netscape and Mosaic are examples of GUI
products.
52. HDTV
- High Definition Television. Because of the larger picture size
(16-by-9 display ratio for HDTV versus 4-by-3 for regular TV) and
more horizontal picture lines, HDTV will have a higher quality
display than conventional TV. Also, HDTV has cd-quality sound and
involves digital transmission instead of analog
53. Hypermedia
- "hypertext" with links not only to text, but also to
other forms of media - sounds, graphics, movies/video, animation.
54.
Key frame - a "complete"
video frame, containing all the image detail, not just the changes
from the previous frame.
55. Layout
- design or outline. The arrangement; location of elements in a work
area or in a product; the arrangement of objects in a publication;
the design and location of elements in a body of work
56.
Luminance
- a color's brightness.
57.
Pixels - PICture ELements =
Pixel. The tiny dots comprising a picture. Look closely at your TV to
see pixeled images.
58. Polyphony
- the total number of sounds a sound card can reproduce at the same
time. A 32-note card can play 32 notes at a time.
59.
Resolution - the clarity of
the displayed/printed image. The more pixels/dots per square inch
(dpi), the finer the detail (higher resolution).
60. Resources
- the materials, tools, information, and time needed to complete a
project (to create a finished product)
61. Sampling
- When coverting video or audio waves to digital format, digitizing
software picks out points along the wave and records or "snapshots"
these points. These "snapshots" can then be replayed in
much the same way that motion pictures are recreated from the
individual frames. The higher the sampling rate, i.e. the more
snapshots/points, per unit time, the more accurate the computer's
representation of the wave.
62. Screen
saver - a visual program
using moving graphics to prevent image burn-in on older monitors.
Newer monitors no longer need this protection
63. Server
also Host - A computer that
acts as a file server. Users at remote computers (i.e. client
computers) are allowed to access information that's stored on the
server, or host computer.
64.
Skew – distorting a
graphic by stretching either the height or the width without regard
to the other
65. Storyboarding
- planning a project by separating and drawing out the events; the
planning out of a project or report in separate frames; planning a
project by separating & drawing out into frames or moments
66.

two different objects; slides, scenes, etc.; passing or changing from
one slide to another
76. Voice
recognition - software
which recognizes spoken commands. Most software has to be
individually trained for each voice, making its general usage
limited.
77. Web Cast
– As broadcast is to TV, a web cast is to the internet. This
technology publishes/broadcasts personalized information to
subscribers. Then, instead of using bookmarks and search engines to
pull down information, users would run a client application that gets
updated with data that is "pushed" down by a server. AKA
Push Web tech or "channel-casting"
