PCI-X (Peripheral Component Interconnect eXtended) is a computer bus and expansion
card standard that enhanced the PCI Local Bus for higher bandwidth demanded by
servers.
PCM
Pulse-code modulation (PCM) is a digital representation of an analog signal.
Quad
Quadraphonic (or quadrophonic) sound – also called 4.0 stereo – uses four channels in
which speakers are positioned at the four corners of the listening space, reproducing
signals that are (wholly or in part) independent of one another.
Rack unit
A rack unit or U (less commonly, RU) is a unit of measure used to describe the height
of equipment intended for mounting in a 19-inch rack or a 23-inch rack (the dimension
referring to the width of the rack).
RF
A radio frequency (RF) connector is an electrical connector designed to work at radio
frequencies in the multi-megahertz range.
RGB
RGB stands for Red Green Blue, and its color model is an additive color model in which
red, green, and blue light are added together in various ways to reproduce a broad
array of colors.
RGBA
RGBA stands for Red Green Blue Alpha. It uses the RGB color model with extra
information, and is normally used as an transparency/opacity channel.
Ring buffer
A circular buffer or ring buffer is a data structure that uses a single, fixed-size buffer
as if it were connected end-to-end. This structure lends itself easily to buffering data
streams.
Safe Area (aka Action Safe Area)
Depending on how a television set is adjusted, viewers can see a larger area than
the Title Area (aka Title Safe Area) . The safe area is in Viz Artist shown as a green
rectangle in the preview window. This area can be considered a “safe margin” to
create a buffer and avoid that elements are butted up against the edge of the screen.
However, the area outside the safe area is often used to place graphics (for example
tickers that run horizontally across the screen) that butt up against the edges of the
screen.
SATA
The Serial Advanced Technology Attachment (SATA) computer bus has the primary
function of transferring data between the motherboard and mass storage devices (such
as hard disk drives and optical drives) inside a computer.
