A circuit on the video module which strips blanking sync and burst from the programme output of the switcher and replaces it with blanking and sync from a reference source. This process ensures that sync and blanking do not contain any unwanted timing shifts, and the record VPR is always receiving constant relationships of sync, blanking, and burst.

In planar modes, the display memory is separated into four independent planes of memory, with each plane dedicated to controlling one colour component (red, green, blue, and intensify). Each pixel of the display occupies one bit position in each plane. In character modes and packed-pixel modes, the data is organised differently.
Industry:Entertainment
An ATV technique that adds information to blanking areas that is supposed to be invisible to ordinary sets but can be used by an ATV set for increased resolution and/or widescreen panels.

A way to alter a video signal to affect the colors. The Video equaliser is suited to this task. See Chroma Corrector.

A dense mesh screen on a microphone, which minimises overload caused by loud, close sounds.
Industry:Entertainment
Describes how close a colour is to the mathematical representation of the color.
Industry:Entertainment
An overloading condition in which white areas appear to flow irregularly into black areas.

A modification to a key to cause it to flash on and off. The speed at which a key blinks.

The mathematical representation of a color. a) Regardless of the colour space used, RGB, YIQ, YUV, a colour will appear the same on the screen. What is different is how the colour is represented in the colour space.
In the HLS colour space, colours are represented based on a three-dimensional polar coordinate system where as in the RGB colour space, colours are represented by a Cartesian coordinate system. b) Many ways have been devised to organise all of a system’s possible colors. Many of these methods have two things in common: a colour is specified in terms of three numbers, and by using the numbers as axes in a 3D space of some sort, a colour solid can be defined to represent the system. Two spaces are popular for computer graphics: RGB and HSV.
