Emergency alert message detection on electronic device based on audio-video information

A method, comprising:

• in an electronic device:
• receiving first media content over a first broadcast channel;
• controlling 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;
• detecting, 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 correspond to an emergency at the geo-location;
• detecting an emergency alert audio in the received first media content;
• determining 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 is less than a threshold value;
• extracting an emergency alert message received over a second broadcast channel associated with the geo-location, based on the detected set of objects, and the determined static display portion, and the detected emergency alert audio in the received first media content;
• and
• controlling an output of an emergency alert signal associated with the extracted emergency alert message.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions that when executed by an electronic device, causes the electronic device to execute operations, the operations comprising:

• receiving first media content over a first broadcast channel;
• controlling 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;
• detecting, 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 correspond to an emergency at the geo-location;
• detecting an emergency alert audio in the received first media content;
• determining 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 is less than a threshold value;
• extracting an emergency alert message received over a second broadcast channel associated with the geo-location, based on the detected set of objects, and the determined static display portion, and the detected emergency alert audio in the received first media content;
• and
• controlling an output of an emergency alert signal associated with the extracted emergency alert message.
