An expensive, brittle metal used to make the shadow mask in a direct-view colour picture tube. Incorporating it allows higher picture contrast levels from the tube without incurring long-term damage to the shadow mask itself. It allows the set manufacturer to offer higher contrast levels.
Since the phosphors in the tube reach the point of blooming well before the need for the Invar mask, anyone properly setting the contrast level for no blooming in the picture won’t ever need the features of the Invar mask. The high contrast levels permitted by the Invar mask will eventually burn the phosphors.

An undesirable, unwanted outline around a matted image.
This is also called Matte Ring, Matte Ride, but more generally called a “bad matte.”
Industry:Software
A philtre that is a complement of the philtre used to reduce interference in the IF section of a television set.
Industry:Software
A key filled with a solid colour instead of “self,” which is the video cutting the key. This colour is internally generated and adjustable in hue, luminance, and saturation.
Industry:Software
We think of a normal key as, for example, letters superimposed over a background. When this key is inverted, the background appears inside the key; it appears we are looking through the cut-out key and seeing the background. The key insert video appears outside the key.
Industry:Software
A spot on the fluorescent surface of a cathode ray tube, which is somewhat darker than the surrounding area because of bombardment by negative ions which reduce the phosphor sensitivity.
Industry:Software
A key effect in which the inserted video is created by a matte generator.
Industry:Software
An arrangement of magnetic fields and apertures which will allow an electron beam to pass through but will obstruct the passage of ions.
