VistaGRAPHX 2500 User's Manual

The distance between the front feet of the projector and the screen. Also called
"Projector-to-Screen Distance”.

Balance of red-to-green necessary for realistic representation of NTSC signals.

The ability of a projector to synchronize to inputs with frequencies within a
specified range.

The frequency at which images are generated. Vertical frequencies vary amongst
sources. Also called vertical scan rate.

The difference between the vertical height of the projector lens and the vertical
height of the display.

The signal that is used by display devices (such as projectors) to generate an
image. This term also refers to the output of video tape/disk players and
computers.

An optional device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M
or SECAM to RGB video.

A specific type of video signal, such as NTSC, PAL, SECAM. VistaGRAPHX
2500 can automatically recognize and display the standard and display
accordingly.

Screens do not reflect equally in all directions. Most light is reflected in a
conical volume centered around the "line of best viewing". Maximum brightness
is perceived if you are within the viewing cone defined by the horizontal and
vertical viewing angles.

The color temperature of white used by the projector.

The area of an image that is white only. For example, a full white field is an
image that is white everywhere. A 10% white field is a white area (usually
rectangular) that occupies 10% of the image; the remaining 90% is black.

See YUV video.

See YUV video.

A high-end signal suitable for broadcast. YUV video (also called component
video or YCrCb video) by-passes the VistaGRAPHX 2500 video decoder.

The adjustment of image size through the use of a zoom lens.
