MPEG
(Moving Picture Expert Group) A family of standards that utilizes
complex compression techniques to encode audio-video information
into a signal.
NTSC
(National Television Systems Committee) A United States based
organization, which develops technical standards for broadcasting.
PAL
(Phase Alternating Line) The European standard for video
broadcast.
PAM
Removable, frequency determining module called the RF Power
Amplifier Module of the CamPac2.
PID
(Package Identifier) Information located at the beginning of a
transmitted packet that tells the receiver what to do with the packet.
QPSK
(Quadrature Phase Shift Keying) A digital frequency modulation
technique where a single phase carrier is modulated into a four
phase signal, with each quadrant represented by a two digit binary
number. The signal is then transmitted and demodulated by the
receiver into frequency independent voltage levels.
SDI
(Serial Digital Interface) A digital video format utilizing a 270 Mbps
(for Standard Definition) or 1.5Gbps (for High Definition) data rate.
The signal consists of a 10-bit, serial interface for both digital video
and four channels of embedded digital audio. SDI requires a
standard 75-ohm BNC connector and coax cable for connection to a
device.
Symbol
A single Symbol can be considered one phase-state of a QPSK
signal. All four Symbols used together can be considered the baud
rate of the signal.
Transport Stream
When several video and analog inputs are multiplexed into a single
data stream for transmission.
