WAV
(pronounced wave): The Windows-compatible audio file
format. The WAV file can be recorded at 11 kHz, 22 kHz, and 44 kHz, and
in 8- or 16- bit mono and stereo. See also: AIF, AU.
Wavelet-based
compression: An
asymmetrical image compression technique that is scalable and can
provide high quality. The drawback is that it becomes more
computationally expensive as the picture resolution and frame rates go
up. The encode and decode are asymmetrical in that one side is a lot
more expensive computationally than the other. The ImMix Cube and
TurboCube used wavelet-based compression.
WebTV:
WebTV
Networks, Inc. is a leading manufacturer of set-top boxes used for
viewing interactive television and regular television. These receivers
let users access the Internet, including use of electronic mail and
online chats. WebTV set-top boxes like the WebTV Plus Receiver connect
to a standard television and a phone line. The WebTV Plus Receiver
supports TV Crossover Links and WebPIP. WebPIP lets users simultaneously
view Web pages and TV programming on the same screen, without a special
picture-in-picture TV. WebTV is a trademark and service of the Microsoft
Corporation.
Widescreen:
Term
given to picture displays that have a wider aspect ratio than normal.
For example, TV's normal aspect ratio is 4:3 and widescreen is 16:9.
Although this is the aspect ratio used by HDTV, widescreen is also used
with normal definition systems.
Window:
1.
Video containing information or allowing information entry, keyed into
the video monitor output for viewing on the monitor CRT. A window dub is
a copy of a videotape with time code numbers keyed into the picture. 2.
A video test signal consisting of a pulse and bar. When viewed on a
monitor, the window signal produces a large white square in the center
of the picture. 3. A graphical user interface that
|
presents
icons and tools for manipulating a software application. Most
applications have multiple windows that serve different purposes.

See also: Pillar box, side panels.
Windows
CE: Microsoft
Windows CE is a 32-bit real-time embedded operating system (RTOS)
designed from the ground up to empower the development of a new range of
emerging computing appliances, including set-top boxes, digital
versatile disc (DVD) drives, entertainment consoles, smart phones,
highly portable and personal computing devices like handheld computers,
and home appliances. Windows CE is modular, allowing use of a minimum
set of software components needed to support receiver requirements. This
uses less memory and improves operating system performance. Windows CE
provides a subset of the Win32 application program interface (API) set,
which provides an effective amount of application source-code level
portability and compatibility and user interface consistency with other
Microsoft Windows operating systems and Windows applications. See also:
Java.
Windows
Media Player: Delivers
the most popular streaming and local audio and video formats, including
ASF, WAV, AVI, MPEG, Quick-Time, and more. Windows Media Player can play
anything from low-bandwidth audio to full-screen video.
WORM:
Write Once/Read Many--describes storage devices on which data, once
written, cannot be erased or re-written. Being optical, WORMs offer very
high recording densities and are removable, making them very useful for
archiving.
WYSIWYG:
What you see is what you get--usually, but not always. Referring to the
accuracy of a screen display to show how the final result will look. For
example a word processor screen showing the final layout and
typeface that will appear from the printer.
