Claim Text:
1. A method, comprising: receiving, by a zone headend device for a local zone, a local emergency alert service (EAS) message that is intended for a particular geographic locality; processing, by the zone headend device, the local EAS message for delivery over a television conditional access system; sending, by a regional headend device for a region of multiple zones including the local zone, a polling signal to the zone headend device; receiving, by the zone headend device and from the regional headend device, a response to the polling signal indicating that a local EAS message has been received; sending, by the regional headend device and to the zone headend device, a first request for the local EAS message; sending, by the regional headend device, another polling signal to another zone headend device for another local zone; receiving, by the regional headend device and from the other zone headend device, a response to the other polling signal indicating that another local EAS message has been received; sending, by the regional headend device and to the other zone headend device, a second request for the other local EAS message; receiving, by the regional headend device, the local EAS message, in response to the first request, and the other local EAS message, in response to the second request; and processing, by the regional headend device, the local EAS message and the other local EAS message for in-band delivery with regional programming for broadcast quadrature amplitude modulation (QAM) and over-the-top streaming; receiving, by the regional headend device, a regional EAS message from an emergency message source; processing, by the regional headend device, the regional EAS message for in-band delivery with regional programming for over-the-top streaming; sending, by the regional headend device, the regional EAS message to a national headend device for multiple regions including the region; receiving, by the national headend device, the regional EAS message; and processing, by the national headend device, regional EAS message and other regional EAS messages for in-band delivery with live linear national programming for over-the-top streaming, wherein each of the zone headend device, the regional headend device, and the national headend device are different devices.
