Abstract

Apparatus and methods for efficiently and flexibly providing emergency alert data (e.g., EAS messages) to subscribers of a content-based network, such as for example Internet protocol television (IPTV) subscribers. In one exemplary embodiment, the apparatus includes a server performing real-time receipt and encapsulation of the EAS data (which may comprise audio, video, and/or text), transport of the EAS data to client devices over the network, and use of one or more applications running on the client devices to decode and display/present the EAS data in a manner which effectively guarantees that it will be perceived by the viewer. In one variant, instant messaging (IM) infrastructure is used to authenticate clients and receive and display at least portion of the EAS data via a separate transport process. Server and client-side apparatus adapted for EAS data receipt, decoding and display are also disclosed.

Claims

1. In a packet network comprising at least one server and a plurality of client devices in direct or indirect signal communication with said server, a method of delivering alert data to one or more of said client devices, said method comprising:

receiving said alert data from one or more alert sources, said alert data comprising video and audio;

formatting said alert data in a format suitable for transport over said network;

delivering said alert data to said one or more client devices over said network;

in response to said delivery of said alert data to said one or more client devices, receiving one or more authentication requests from said one or more client devices;

authenticating said one or more client devices; and

when said one or more client devices are authenticated, causing said client devices to;

(i) display at least a first portion of said video alert data on a display device associated with respective ones of said client devices; and

(ii) present said audio alert data in place of said audio of at least one multimedia program being contemporaneously viewed on said display device.

2. The method of claim 1, wherein said network comprises at least one multimedia server configured to send multimedia programs, and at least one data server different from said multimedia server and configured to send said alert data.

3. The method of claim 1, further comprising causing said client devices to access one or more selected program streams carrying video signals relating to said alert data.

4. The method of claim 1, wherein said act of formatting comprises creating multiple packet formats for the same data, said packet formats being selected to be consistent with one or more differing requirements or capabilities of different ones of said plurality of client devices.

5. The method of claim 1, wherein said act of delivering is performed by using an Internet Protocol (IP) transport for said alert data different from that used for said at least one multimedia program.

6. The method of claim 1, wherein said act of delivering for at least a portion of said alert data is performed by using an Internet Protocol (IP) transport that is the same as that used for said at least one multimedia program.

7. The method of claim 1, wherein said act of authenticating is performed using at least an instant messaging-based authentication mechanism.

8. A method of distributing both media content and emergency alert information over a packet network, said method comprising:

receiving emergency alert information, said alert information comprising at least video;

generating alert data relating to said alert information, said alert data comprising at least one alert video stream;

inserting said generated alert data into a content stream comprising at least said media content;

transmitting said single content stream to said one or more client devices over said packet network; and

directing said one or more client devices to display at least a first portion of said alert data on respective display devices associated therewith.

9. The method of claim 8, further comprising formatting said alert data, said formatting comprising creating multiple packet formats for the same data, said packet formats being selected to be compatible with the capabilities of various different ones of said one or more client devices.

10. The method of claim 8, wherein said alert information further comprises an audio portion.

11. The method of claim 10, wherein:

said packet network comprises at least one multimedia server configured to send multimedia programs; and

said act of directing further comprises directing said one or more client devices to present said audio portion of said alert data in place of said audio of at least one of said multimedia programs.

12. The method of claim 8, wherein said alert information is received via an over-the-air (OTA) broadcast.

13. The method of claim 8, wherein said packet network comprises at least one multimedia server configured to send multimedia programs, and wherein said method further comprises:

delivering said one or more multimedia programs to said one or more client devices over a first transport stream associated with a first process running on said one or more client devices; and

delivering said alert data to said one or more client devices over a second transport stream different from said first and associated with a second process running on the same ones of said one or more client devices on which said first process is running.

14. The method of claim 8, wherein said act of directing further comprises causing said client devices to access one or more selected program streams carrying video signals relating to said alert data.

15. The method of claim 8, further comprising authenticating at least one of said client devices prior to said transmitting said alert data thereto.

16. A method of providing emergency alert system (EAS) services to a non-EAS enabled device in an IPTV-enabled network via at least one server entity, said method comprising:

authenticating said at least one server entity;

receiving from one or more alert sources EAS data in a first format;

converting said EAS data from said first format to a second format, said second format being suitable for transport over said network; and

providing said EAS data to said non-EAS enabled device, said non-EAS enabled device comprising at least an IPTV video decoder, said IPTV video decoder of said non-EAS enabled device decoding and displaying at least a first portion of said EAS data.

17. The method of claim 16, wherein said act of providing said EAS data comprises unicast delivery to said non-EAS enabled device.

18. The method of claim 16, wherein said act of providing said EAS data comprises multicast or broadcast delivery to a plurality of non-EAS enabled devices in said IPTV network.

19. The method of claim 16, wherein said EAS data is provided to said non-EAS enabled device based at least in part on a geographic location of said device, said geographic location being determined at least in part by at least one of (i) a MAC address, and/or (ii) an IP address, of said device.

20. The method of claim 16, wherein said method further comprises authenticating said non-EAS enabled device.

21. The method of claim 20, wherein said act of authenticating comprises sending and receiving a series of messages between said non-EAS enabled device and said server entity.

22. The method of claim 21, wherein said act of authenticating further comprises sending and receiving messages to and from a digital certificate authority (CA) server.
