Abstract: A method and apparatus for event-based media playback. A media device infers one or more actionable events in a media content item using one or more neural network models and determines a respective start location for each of the actionable events in the media content item. The media device receives user input indicating a selection of one of the actionable events and selectively initiates playback of the media content item at the start location associated with the selected actionable event.
