Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable storage mediums for receiving media data. One apparatus includes processing circuitry that receives a media presentation description (MPD) file that includes an MPD event indicating a plurality of branches of a story map. The processing circuitry determines whether a user selection from among the plurality of branches of the story map is received during an active duration of the MPD event. Based on a determination that the user selection is received during the active duration, the processing circuitry receives, from a server, media data corresponding to the user selected branch. Based on a determination that the user selection is not received during the active duration, the processing circuitry receives, from the server, media data corresponding to a default branch in the plurality of branches of the story map.
