Appendix Glossary
MARKERS
-- pointers (arrows, cross hairs, dots), frames, date/time labels, freehand draw ings
and straight lines which can be placed and anchored on a Pointmaker marker
overlay.
NTSC
-- the commonly accepted term describing the composite color version of the EIA
RS-170 video standard. The color version of EIA RS-170 is in process of standard-
ization by the Electronics Industries Association (EIA). NTSC is used in North
and South America, Japan and most of Asia.
OVERLAY
-- a combination of one or more markers placed on the screen using the capa-
bilities of the Pointmaker. These markers overlay a chosen video image. While the
markers are visible, the actual overlay is invisible, allowing you to mark directly on
top of a video image (or solid background if selected in the menu system).
POINTERS
-- the 8 different arrows, 2 cross hairs and 2 dot pointers which may be selected
and placed on a Pointmaker overlay, in any number and in combina tion with
other markers. Pointers are considered markers. However, not all markers (such as
frames) are pointers.
PRESS
-- on the keyboard, the action of pressing then releasing the function key. On
auxiliary controllers, a press is often the action of depressing and not releasing a
button until the desired effect takes place on the screen (as opposed to a click of
the button).
PROXIMITY
-- a feature of the CPN-5000 that affects the digitizing tablet. When proximity is
activated, the active pointer automatically disappears each time the pen is lifted
from the drawing area.
UNDO
-- the Pointmaker function that allows you to undo anchored markers on an
overlay one at a time, beginning with the most recently anchored marker.
VIDEO SOURCE
-- a device from which the Pointmaker receives a video image, incorporates the
Pointmaker graphic overlay capabilities, then outputs to the corresponding
display. Examples of video sources include VHS recorder/players, cameras, VGA
computers, standard television sets, teleconference equipment, slide-to-video
converters, visual presenters and more. In the PVI-46 model, the source is usually
a VGA or Macintosh computer or laptop.
