P
PAL

Phase Alternate Line. Television standard used in Western Europe, Australia, Britain and South Africa. A PAL picture is composed of 625 horizontal, interlaced lines refreshed at 50 fields per second. The Chrominance subcarrier is of 4.43 MHz.

PAL-M

Brazilian version of the PAL standard composed of 525 horizontal, interlaced lines refreshed at 60 fields per second. The Chrominance subcarrier is of 4.43 MHz.

PATTERN GENERATOR

Device which generates known reference pictures, enabling adjustments to be made.

PERIOD

Time taken by a periodic signal to execute a cycle. See Frequency.

PHOENIXTM

Audio pin screw terminals, see MCO.

PIP

Picture in Picture.

PITCH

Distance that separates 2 pixels in a display.

PIXEL

Abbreviation for picture element. A pixel is the smallest element (Black and White or Color) that makes up an image. Pixels make up lines and columns and define the resolution of the picture. E.g. XGA = 1024 x 768 = 1024 pixels x 768 lines = 786432 pixels per image.

POLARITY

Positive or Negative sign of a signal.

PROGRESSIVE

see non-interlaced.

PULL DOWN (2/3)

Method for transfering Film Image (24/sec) to video (30/sec) in USA & Japan. Image sequence is 2/3/2/3 with 2+3=5 Fields redundancy.

Q
QHXGA

Quad Hex eXtended Graphics Array - Standard computer format consisting of 8192 x 6144 pixels. The aspect ratio is 4:3.

QSXGA

Quad Super eXtended Graphics Array - Standard computer format consisting of 2560 x 2048 pixels. The aspect ratio is 5:4.

QUAD HDTV

A Quad HDTV image consists a computer format of 3840 x 2160 pixels. The aspect ratio is 16:9. It is equivalent to 4K with a definition of 4096 x 2160 pixels while maintening the aspect ratio of 16:9.

QUADRAVISION®

A specific mode from Analog Way. Quadravision® allows to display up to 4 lives sources on a screen with seamless effects.

QUXGA

Quad Ultra eXtended Graphics Array - Standard computer format consisting of 3200 x 2400 pixels. The aspect ratio is 4:3.

QXGA

Quad eXtended Graphics Array – Standard computer format consisting of 2048 x 1536 pixels. The aspect ratio is 4:3.

R
RCA™ CONNECTOR

CINCH coaxial connector, usually used for audio signal (red = right, white = left) or composite video signal (yellow = C.Video). Sometimes called Phono plug.

REAL TIME CONVERSION

Feature of a converter that treats, calculates and renders an input signal to its output in a very short time (almost instantaneously). This operation is not visible to the naked eye.

RECLOCKING

Reclocking is a process that is used to restore the clock rate attributes of a digital signal.

REDUCED BLANKING

A method of eliminating portions of the BLANKING time that are no longer necessary on digital displays, to allow for larger resolutions at lower BANDWIDTHs.

REFRESH RATE

Rate for redrawing a frame on the video image field or frame (Hz). It is the "Vertical" Frequency rate which is related to the flicker of the picture.

RJ45

Connector used for Ethernet devices that holds up to eight wires.

REMOTE CONTROL

Device or program enabling another device to be controlled from a distance.

RESOLUTION

Amount of horizontal and vertical information contained in an image. Composite NTSC is a 350 x 480 resolution and XGA (Computer) is a 1024 x 768 resolution. The higher the resolution, the better and sharper the picture will be.

RGB

Abbreviation for Red, Green and Blue. The 3 primary colors of light that are the basic additive components of the color television system and computer image. The weighted sum of R,G,B signals gives a "white" color, visible to the naked eye.

RGB HV

RGB signal with separated Horizontal sync. and Vertical sync.. The signal is transmitted by a 5 wires coaxial cable. It is usually used for PCs and is compatible with most computers.

RGB S

RGB signal with composite sync. which is transmitted by a 4 wires coaxial cable. Sometimes called RGB sync.

RS232

A worldwide serial digital interface standard used for the remote control of many devices usually used in the Audio and Video Industrial, fields.

R-Y
