ATSC 3.0 advertising notification using event streams
An Event Streams ‘event’ which contains information about ads is sent via ATSC 3.0 to a receiver player along with an xlinkResolution signal. This information includes but is not limited to time stamps for when the ads will start and stop. When this xlinkResolution is sent to the receiver player, the receiver player sends a notification to a broadcaster app containing the information about start and stop time for presenting the ad. Using this information, the broadcaster app updates itself so that, for example, the broadcaster app can present a message on a user interface regarding the subject of the ad, or present content related to but different from the ad along with the ad itself.

receiving first content from a source of content;
presenting the first content on at least one output device;
receiving at least one data element indicating replacement content;
sending, from a receiver app to a broadcaster app, information related to the data element;
identifying, using the broadcaster app, the replacement content using the information related to the data element;
sending, from the broadcaster app to the receiver app, indication of the replacement content to be presented in lieu of original content along with at least one start time of play of the replacement content;
commencing play of the replacement content at the start time;
sending, from the receiver app to the broadcaster app, indication of the start time; and
responsive to receiving from the receiver app the indication of the start time, the broadcaster app updating itself at least in part by presenting a message on a user interface (UI) about the replacement content, or presenting content on the UI that is related to the replacement ad, or both.
