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 receives a user selection of one of the plurality of branches of the story map during an active duration of the MPD event. The user selected branch corresponds to a next period that is connected to a current period. The processing circuitry receives, from a server, media data of the next period corresponding to the user selected branch.
