Multipath The radio wave propagation phenomenon that results in the transmitted
signals. reaching the receiving antenna by two or more paths. This condition is
not desirable and usually results in signal fading and interference.
MUX
Multiplex
The combining of multiple signals into a single transmission.
NIT Network Information Table
Omni-Directional
Antenna
The final transmit element of the microwave system that radiates the signal
approximately equally throughout a 360 degree circle. Does not require aiming
of the antenna.
PAL phase-alternating
line
A color encoding used in broadcast television systems in large parts of the
world.
PAT
Program Association
Table
Indicates which PID the PMT is to be found
PID Packet Identifier
PMT-PID
Program Map Table
Yields information about the Program, Video PID, Audio PID, and PCR PID.
The PMT-PID default is 200 for BMS systems.
PCR-PID
Program Clock
Reference
A time stamp indicating the system time clock value when the stamped packet
leaves the encoder buffer and enters the decoder buffer used to Synchronize
the receiver System Time Clock (STC) with the transmitter STC. Default is 101
for BMS systems.
RF: Radio Frequency That portion of the Electromagnetic Spectrum that is used for radio and
television transmission.
SDI: Serial Digital
Interface
A digitized video format used for broadcast grade video.
SDT Service Description Table
Stand-by The condition of an RF system where all but the transmit circuits are
energized. In this status the system may be switched into transmit mode
instantaneously. (See Transmit)
TNC Connector Threaded version of the BNC connector (See BNC connector)
Transmit The condition of an RF system where it is sending out signal. (See Stand-by)
YUV The YUV model defines a color space in terms of one luminance and two
chrominance components. YUV is used in the PAL system of television
broadcasting, which is the standard in much of the world.
