Matrix switcher – In audio/video, a means of selecting an input source and connecting it to one or more outputs. A Matrix switcher would normally have multiple inputs and multiple outputs.

MHz (as in 8 MHz) – An abbreviation for megahertz. This is a unit of measurement and refers to a million cycles per second. Bandwidth is measured in megahertz.

Milli m – Abbreviation for one thousandth. Example: 1 ms = 1/1000 second.

Monitor – (A) A TV that may receive its signal directly from a VCR, camera or separate TV tuner for high quality picture reproduction. It may not contain a channel selector. (B) A video display designed for use with closed circuit TV equipment. (C) Device used to display computer text and graphics.

Non-Interlaced– Also called progressive scan – a method by which all the video

scan lines are presented on the screen in one sweep instead of two (also see interlaced).

Nonvolatile memory – Memory that retains data when power is turned off.

NTSC National Television Standards Committee – Television standard for North America and certain countries in South America. 525 lines/60 Hz (60 Hz Refresh).

Output – The product of an operation by a device going to some external destination, such as another device, a video screen, image or hard copy.

PAL Phase Alternate Line – The phase of the color carrier is alternated from line to line. It takes four full pictures for the color horizontal phase relationship to return to the reference point. This alternation helps cancel out phase errors, the reason the hue control is not needed on PAL TV sets. PAL, in its many forms is used extensively in Western Europe.

Peak-to-Peak– abbreviated p-p– The amplitude (voltage) difference (as displayed on an oscilloscope) between the most positive and the most negative excursions (peaks) of an electrical signal.

Peaking – A means of compensating for mid and high frequency RGB Video Bandwidth response in data monitors and projectors and for signal losses due to cable capacitance. When using the Peak enhancements, use the following guidelines for proper output settings: Use 50% with all computer frequencies between 15-125 kHz at any cable length. Use 100% with high frequency computers of 36 kHz or higher with cable lengths 75 feet or greater.

Pincushion – The inward or outward (curved) appearance of the edges of a display.

Pin-out– An illustration or table that names signals, voltages, etc. that are on each pin of a connector or cable.

Plenum Cable – Cable having a covering that meets the UL specifications for resistance to fire.

PLUGE Picture Line Up Generation Equipment – This is a name of a test pattern that assists in properly setting picture black level. PLUGE can be part of many test patterns. The phrase and origination of the test signal are both credited to the BBC.

Power Electrical – The dissipation of heat by passing a current through a resistance. Measured in Watts (W), it is expressed by Ohm’s law from the two variables: Voltage (E) and Current (I). i.e. P = I2xR, or, P = E2/R or P = ExI

Resolution – The density of lines or dots that make up an image. Resolution determines the detail and quality in the image.

A)A measure of the ability of a camera or television system to reproduce detail.

B)In video, generally called horizontal resolution. It can be evaluated by
