An explanation of conventions used in this FAQ

RGB  = Red Green Blue

S = Combined 5V TTL level sync (also as H/V and Mixed sync) 

s = 0.3V low voltage mixed sync

R (as in 75R) is Ohms impedance

PAL = Phase Alternate Line = Video system adopted in the UK

NTSC = Video system adopted in the USA (National Television Systems Committee)

H = Horizontal sync 

HD = Horizontal Drive almost the same as horizontal sync (see text)

V = Vertical Sync

VD = Vertical Drive almost the same as vertical drive (see text)

H/V = S = Combined (mixed) 5V TTL level sync

YUV = See component video section

Y Cr Cb = See component video section

Y Pr Pb = As above 

TTL = Transistor Transistor Logic - a  series of logic integrated circuits with pre-defined input characteristics all working off 5 volts

VSWR = Voltage Standing Wave Ratio or in English a measure of how well or poorly a cable and piece of equipment are matched, poorly matched cables can result in reflection of some of the signal back down the cable with distorted and generally poor results

VCR = Video Cassette Recorder

STB = Set Top Box i.e. A Digital terrestrial TV box or cable /  satellite box

BNC = bayonet type Plug and socket lock together used for video mostly. typically RGBS or Y Cr Cb

Phono = Plug sometimes referred to as RCA or Cinch usually used for audio can be used for composite video (yellow) or Component video Cr being Red Cb being blue and Y being green. Also coded Red green and blue for RGsB with sync on green. Often also used for digital audio.

Scart = 21 pin connector found mostly on European TVs VCR's and STB's see the RGB section for more detail

SVGA  = VGA stands for Video Graphics Array the "S" simply added super to it. It is the standard adopted for computer to monitor connections and has also found it's way onto displays designed for more general use like projectors and plasma screens. VGA has very approximately the same resolution as a TV picture. SVGA has greater resolution. VGA used a 9 pin D sub plug and socket the SVGA extended this to a 15 pin high density D sub ( not to be confused with the standard 15 pin D sub!!). further increases in resolution mean we now have XGA and SXGA to contend with. Monitors designed specifically for computer use will not normally display interlaced video see below
