Jackson, MS, and Columbia, MD - Oct 15, 2012 - Global Security Systems (GSS), the systems integrator and service provider of GSSNet, Alert FM and Alert Studio, and iBiquity Digital have teamed to deliver a comprehensive Emergency Alert System (EAS) that provides emergency audio and text content over analog FM and HD Radio.
The system is Common Alert Protocol-compatible (CAP) and Integrated Public Alert and Warning System-compliant (IPAWS). In addition, multi-channel HD Radio technology empowers emergency officials to potentially broadcast different languages using different channels during a crisis.
HD Radio permits comprehensive text messaging with actionable control information to be delivered via HD Radio, allowing a receiver to remain in standby mode - a reduced power state - until an alert activates that receiver. Using GSS technology, complementary brief text messages can be provided by the Alert FM RBDS-based system.
An alert message can be originated by Alert Studio and delivered from any applicable IPAWS (or other) alert depository to the radio station, via the GSSNet satellite data delivery system. After satellite distribution, the audio and text message can be processed by an alert processor and then distributed to the analog FM system, HD Radio system, and Alert FM RBDS-based system for broadcasting OTA.
On the receiver side, the alert messages are heard on analog FM and HD Radio receivers. Enabled HD Radio receivers can display comprehensive text, store it and further act on the provided content. Enabled ALERT FM RBDS-based text receivers may display brief text. Receivers that support both technologies may refine the cooperating receiving systems, thus enhancing the user experience.
The system is currently installed and operational on two Greater Media HD Radio stations in the Detroit market. According to Mike Kernen, chief engineer, Greater Media Detroit, "The combination of HD Radio Technology and capabilities provided by GSS offers the most complete alert and warning content in the broadcast radio environment."
