MISSION


PAQ4411.1

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


PAQ4411.1

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 pre-configured “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 consultation…

ANNEX


PAQ4411.1

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

Broadcast Manager


PAQ4411.1

CARTOGRAPHIC INTERFACEa 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 TOOLGroups 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
