Video Decoder ➤ A device that converts NTSC, PAL, SECAM or NTSC 4.43 video to
RGB video (Multi-standard Decoder).
Viewing Angle ➤ Screens do not reflect equally in all directions. Most light is reflected in
a conical volume which is centered around the "line of best viewing".
Maximum brightness is seen when you are positioned within the viewing
cone. The horizontal and vertical viewing angles are the horizontal and
vertical angles of the cone.
White Balance ➤ White Balance refers to the color temperature of white used by the projector.
White Field ➤ A white field is 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.
