Common distribution and rendering for emergency alert services

摘要

A system and method for are provided for common distribution and rendering of communications capability for emergency alert services. A zone headend device, for a local zone, receives a local emergency alert service (EAS) message that is intended for a particular geographic locality. The zone headend device processes the local EAS message for delivery over a television conditional access system and sends the local EAS message to a regional headend device for a region of multiple zones including the local zone. The regional headend device receives the local EAS message and another local EAS message from another zone headend device. The regional headend device processes 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.

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.
