MISSION
HD Monitoring MARCH 2008
PAQ4411.1
GoldenEagle HD mission
To help broadcasters to keep their listeners loyal
By monitoring 24/7 quality and continuity of the HD signals
By ensuring a transparent blend between digital and analog
programs (time and level alignment)
To help broadcasters to comply with FCC rules
By monitoring the NRSC mask,…
By triggering automatic actions when facing out of tolerance
conditions
To help broadcasters with their HD transitions
By providing innovative tools with permanent and automatic
monitoring capabilities as well as remote control capabilities.

PHILOSOPHY
HD Monitoring MARCH 2008
PAQ4411.1
Philosophy
A smart modulation monitor
GE HD can monitor multiple stations continuously on an automatic
scanning cycle, using an external antenna or directly connected to
the RF probe
GE HD makes sure the critical parameters are within preconfigured “normal” windows
Out of tolerance conditions automatically generate an alarm
(emails, voice message, relay, SNMP trap), and/or automatic
actions
GE HD can be reached remotely via TCP/IP for real-time
measurements, audio streaming, configuration, event log

Broadcast Manager
BROADCAST MANAGER is an optional software package for
remote monitoring of multiple broadcast sites. It is a userfriendly web server system that can manage configuration,
alarms, measurements and data from remote GOLDENEAGLE
HDs and other Audemat-Aztec monitors.

Broadcast Manager
CARTOGRAPHIC INTERFACE
a map interface displays a clear and immediate view of the
status of all stations in your network. (3 levels of zoom).
REAL TIME ALARM MANAGEMENT
The map allows the user to see quickly which site has
an alarm on it by a flashing red light .The user can access
the equipment and analyze the alarm directly from this map.
Enhanced rerouting of alarms to engineers (Fax, Email, SMS).
Last 3 alarms can be displayed on all MANAGER pages.
STRATEGIC DECISION MAKING TOOL
Groups all relevant information from the network into
centralized open database.
Database can be filtered and sorted to generate statistics
for decision making purposes.
These statistics provide a clear view of network efficiency
and enable the user to optimize maintenance tasks
