Abstract
Providing emergency alert system (EAS) alerts to IP-based devices inside and outside a home is contemplated. The EAS alerts may be provided through television signals for output on one or more televisions and simultaneously to Internet-Protocol (IP)-based devices such as tablets, game consoles, cellular phones, mobile computer, IP-STBs, televisions with IP connectivity or non-television dependent devices.
Claims20
A system for providing emergency alerts comprising:
- a service provider configured to transmit television signals, the service provider being configured to transmit a first emergency alert system (EAS) message with the television signals, the service provider being configured to generate the first EAS message in response to receipt of an EAS source message from an emergency entity;
- and
- a gateway configured to process the television signals for output by a television, the gateway being configured to embed the EAS alert within the television signals output to the television according to information included within the first EAS message, wherein the gateway is further configured to transmit a first URL to a first device, the first URL pointing to a first EAS manifest stored at the gateway, the first device using the first URL to download the first EAS manifest from the gateway for use in generating the EAS alert.
A non-transitory computer-readable medium having computer-readable code embodied therein for controlling a gateway to facilitate an emergency alert system (EAS) alert, the computer-readable medium comprising instructions sufficient for:
- receiving an EAS message used to define the EAS alert;
- embedding the EAS alert within television signals output to a television connected via a wired connection to the gateway;
- generating an EAS manifest file having instructions sufficient to facilitate output of the EAS alert with a local device connected via a wireless connection to the gateway;
- and
- transmitting a universal resource locator (URL) to the local device, the URL pointing to a storage location on the gateway from which the local device downloads the EAS manifest file in order to output the EAS alert.
A method for providing an emergency alert system (EAS) alert comprising:
- receiving an EAS source message from an emergency entity, the EAS source message identifying the EAS alert;
- identifying a plurality of devices through which the EAS alert is to be output;
- identifying at least a first device and a second device of the plurality of the devices to be associated with a first gateway, the first gateway being configured to process television signals for output by the first device and to provide Internet access to the second device;
- identifying at least a third device of the plurality of devices to be connected to the Internet through a second gateway;
- transmitting a first EAS message to the first gateway, the first EAS message being sufficient to facilitate:
- i) instructing the first gateway to embed the EAS alert within the television signals;
- ii) storing a first EAS manifest file at the gateway, the first EAS manifest file having instructions operable with the second device to facilitate output of the EAS alert;
- iii) instructing the gateway to transmit a first locator pointing to the first EAS manifest file stored at the first gateway to the second device, the first locator instructing the second device to download the first EAS manifest file to facilitate output of the EAS alert;
- transmitting a second EAS message to a web server, the second EAS message being sufficient to facilitate:
- i) storing a second EAS manifest file at the web server, the second EAS manifest file having instructions operable with the third device to facilitate output of the EAS alert
- ii) instructing the web server to transmit a second locator pointing to the second EAS manifest file stored at the web server to the third device, the second EAS manifest instructing the third device to download the second EAS manifest file to facilitate output of the EAS alert.
