  1. HD FM/AM MONITORING GOLDENEAGLE HD HD Monitoring MARCH 2008

  2. Agenda • The facts • GoldenEagle HD mission • Philosophy • Description • Main features • Innovative features • Communication • Conclusion

  3. THE FACTS HD Monitoring MARCH 2008

  4. TheFacts • Developed based on Clear Channel specifications • First unit delivered to Clear Channel in October 2005 • About 600 units on the field in February 2008 • The most complete HD monitor on the market • New firmware release V1.5 now available

  5. MISSION HD Monitoring MARCH 2008

  6. 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.

  7. PHILOSOPHY HD Monitoring MARCH 2008

  8. 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 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…

  9. DESCRIPTION HD Monitoring MARCH 2008

  10. Description • Several products in one chassis: 4 in 1 = Monitoring HD FM/AM +SPS Tx Remote control (option) Monitoring Analog AM/FM/RDS Spectrum Analyzer/ Digital Demodulator (option) + + + • 3 versions • FM, AM and FM/AM

  11. Rear panel RF input for the analog FM receiver Slots for I/O (remote control) 2 Ethernet ports RF input for the HD receiver (AM) AES output RF input for the HD receiver (FM) 4 USB ports for tunneling/API VGA Output for Touchscreen display or external monitor L and R analog outputs RF input for the spectrum analyzer RS232 for tunneling/API

  12. Description Monitoring... ... at the studio… … at the transmitter site… …in any reception area…

  31. ANNEX HD Monitoring MARCH 2008

  32. Broadcast Manager 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.

  33. 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
