1. An electronic device, comprising:
circuitry configured to:
receive first media content over a first broadcast channel;
control a display device associated with the electronic device to render second media content, wherein the second media content is different from the first media content;
detect, from the received first media content, a set of objects associated with a geo-location corresponding to the electronic device, wherein the set of objects corresponds to an emergency at the geo-location;
detect an emergency alert audio in the received first media content;
determine a static display portion in at least one image frame of the received first media content based on the detected set of objects, wherein the static display portion corresponds to a portion of the at least one image frame in which a rate of change of pixel location of the detected set of objects is less than a threshold value;
extract an emergency alert message received over a second broadcast channel associated with the geo-location, based on the detected set of objects, the determined static display portion, and the detected emergency alert audio in the received first media content; and
control an output of an emergency alert signal associated with the extracted emergency alert message.
