Avoiding Cellular Congestion in Emergencies
Using conventional TV broadcasts that are enhanced with data and Mobile DTV transmissions, the Mobile EAS demonstration shows the system's capabilities. The system will deliver multimedia alerts (utilizing video, audio, text, and graphics) to Mobile DTV-equipped cellphones, tablets, laptops, and in-car navigation systems. Utilizing the inherent one-to-many architecture of broadcasting, M-EAS alerts to mobile devices avoid the roadblocks and chronic congestion of cellular systems during emergencies.
The Mobile EAS system would complement the recently activated cellular-based system that transmits up to 90-character text messages to mobile phones.
"Mobile DTV will be a significant enhancement for local public safety communications because millions of devices will receive alerts simultaneously – just as easily as reception by a single device. Video, photos, graphics of evacuation routes, text and audio can all be transmitted through the system to reach anyone with a mobile device, including those with disabilities," said Wayne Luplow, vice president for LG's Zenith R&D subsidiary, which together with PBS developed the core technology enabling M-EAS.The new alerting application developed for Mobile EAS utilizes existing standards for implementation. The U.S. broadcast standard for mobile television, the ATSC A/153 Mobile DTV Standard, uses Internet Protocol (IP) at its core. The use of IP allows the new application to be flexible and extensible. Data delivery, non-real-time delivery, and electronic service guides are all included. Mobile EAS is compliant with the international Common Alerting Protocol and designed for full incorporation into the U.S. Integrated Public Alert and Warning System. www.MobileEAS.org SOURCE MobileEAS.org
