An apparatus for receiving media data, the apparatus comprising:

• processing circuitry configured to
• receive a media presentation description (MPD) file that includes an MPD event indicating a plurality of branches of a story map;
• determine 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,
• receive, from a server, media data corresponding to the user selected branch;
• and
• based on a determination that the user selection is not received during the active duration,
• receive, from the server, media data corresponding to a default branch in the plurality of branches of the story map.

A non-transitory computer-readable storage medium storing instructions which when executed by a computer for receiving media data cause the computer to perform:

• receiving a media presentation description (MPD) file that includes an MPD event indicating a plurality of branches of a story map;
• determining 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,
• receiving, from a server, media data corresponding to the user selected branch;
• and
• based on a determination that the user selection is not received during the active duration,
• receiving, from the server, media data corresponding to a default branch in the plurality of branches of the story map.
