Glossary
DMP-8000:
a Digital Media Player that sends display content to the Video Image Processor (VIP).
Lanyard attachment ring:
a ring found on the back of each module and on the display doors
that attaches to a lanyard and prevents the module from falling.
Light Emitting Diode (LED):
a low-energy, high-intensity lighting unit.
Line filter:
a device that removes electromagnetic noise from the power system to avoid
interference with local communication channels.
Louver:
a plastic shade positioned horizontally above each pixel row. Louvers increase the
contrast level on the display face and direct LED light for easier viewing.
Module:
a display board with LEDs, a driver board or logic card, a housing, a module latch
assembly, and a louver. Each module is individually removable from either the front or rear of the
display.
Module latch:
a safety device that mechanically holds the module firmly in the display. The
latches are centered near the top and bottom of the module.
Pixel:
the smallest single point of light on a display that can be turned on and off. For LED
displays, a pixel is the smallest block of light-emitting devices that can generate all available
colors.
Power supply:
a display component that converts incoming AC line voltage to low DC voltage.
In the BLD series, one power supply powers multiple modules, one controller, or a ProLink Router
(PLR).
ProLink Router (PLR):
a data interface component that receives a signal from the display control
system and converts and distributes the signal. There is typically one PLR per display section.
Remote power controller:
a device capable of remotely controlling the display and
components. Current billboards use either an iBoot PDU or optional SmartLink
TM
.
Serial Advanced Technology Attachment (SATA):
a type of cable that allows high speed signal
from flow from device to device. In digital billboards, these cables run signal from module to
module and from the PLR to the modules.
Termination block:
an electrical point usually used to connect internal power and signal wires to
wires of the same type coming into the display from an external source.
VIP-5160:
a Video Image Processor that sends video signal to the display and controls dimming,
color settings, and test patterns.
Webcam:
a camera connected to the internet used to monitor the display. Current billboards
use a Mobotix PoE camera.
