Wi-Fi Wi-Fi
connect digital devices without the need for cables. It is mostly used
for wireless broadband access and inexpensive consumer wireless
antennas are available at electronics stores.
Widescreen Any aspect ratio that is wider than 4:3. Widescreen televisions are
16 units wide and 9 units tall. Common widescreen film aspect ratios
are 1.66:1, 1.85:1 and 2:35:1.
WMA Windows Media Audio. Similar to MP3 but considered a more
efficient compressor allowing for smaller file sizes for a given quality.
WSXGA WSXGA defines a class of SXGA displays with a width resolution
sufficient to create an aspect ratio of 16:9. A WSXGA display has
1920 to 1600 pixels horizontally and 1080 to 900 pixels vertically.
WXGA WXGA defines a class of XGA displays with a width resolution
sufficient to create an aspect ratio of 16:9. A WXGA display has 1366
to 1280 pixels horizontally and 768 to 720 pixels vertically.
XGA XGA is a display resolution measuring 1024 pixels horizontally and
768 pixels vertically giving a total display resolution of 786,432
individual pixels. XGA has a 4:3 aspect ratio.
XLR Balanced connection for audio components and used professionally.
XviD A free and open source MPEG-4 video codec that was created by
a group of volunteer programmers trying to overcome the closed
source and platform limitations of DivX (XviD spelled backwards).
Y/C DeNOTAs a separated luminance/chrominance signal. Also called S-video.
Offers higher resolutions and no cross interference between colour and
black and white (luminance) signals which shows itself as dot crawl.
Y/Cb/Cr Digital component video. Y stands for the luma signal itself and Cb
is the blue signal subtracted from luma and finally, Cr equals the red
signal subtracted from the luma signal.
Y/Pb/Pr Analog component video. Y stands for the luma signal itself and Pb
is the blue signal subtracted from luma and finally, Pr equals the red
signal subtracted from the luma signal.
Zoom Lens A lens with a variable focal length providing the ability to adjust the
size of a projected image without moving the projector or provide
a range of projector placements that can produce the same size
image. See Zoom Ratio.
Zoom Ratio Zoom ratio is the ratio between the smallest and largest image a lens
can projector from a fixed distance. For example, a 1.4:1 zoom lens
ratio means that a 10 foot image without zoom would be a 14 foot
image with full zoom. Conversely, a 10 foot diagonal image at 15 feet
with no zoom would still be a 10 image at 21 feet at maximum zoom
(15 x 1.4 = 21 feet). A zoom lens is "not as bright" as a fixed lens,
and the higher the ratio, the less light output.
