The device may determine whether to retrieve a media resource associated with the emergency alert message based on the parsed syntax elements.
Claims5
A primary device for transferring an advanced emergency alert table, the primary device comprising:
- a processor, and
- a memory associated with the processor;
- wherein the processor is configured to transfer the advanced emergency alert table to a companion device,
- the advanced emergency alert table includes (i) a header element representing a container for a basic alert envelope, (ii) an advanced emergency alert text element containing a specific text of an emergency notification and (iii) optionally a live media element containing information of emergency-related live Audio/Visual service and a media element containing component parts of a multimedia resource,
- the header element includes an event description element representing a description of an emergency event, wherein the event description element includes a first language attribute representing a code denoting a language of a respective element of the event description element,
- the advanced emergency alert text element includes a second language attribute representing a code denoting a language of a respective element of the advanced emergency alert text element,
- the first language attribute is represented by formal natural language identifiers and not exceed 35 characters in length as defined by BCP 47, and
- the second language attribute is represented by formal natural language identifiers as defined by BCP 47, and not exceed 35 characters.
