1. A method for processing media data, comprising:
receiving an omnidirectional bitstream, wherein the omnidirectional bitstream comprises an overlay control structure of omnidirectional media format (OMAF), wherein the overlay control structure comprises an associated region structure (AssociatedSphereRegionStruct) indicating information about a region associated with an overlay, wherein the omnidirectional bitstream further comprises, in the overlay control structure, trigger type information for the region associated with the overlay, wherein the trigger type information comprises information describing a trigger operation that is one of an action of a user or a state of a user, and wherein the information about the region associated with the overlay is sphere region information;
obtaining, the overlay and the information about the region associated with the overlay, wherein the information about the region associated with the overlay indicates the region associated with the overlay; and
displaying the overlay in response to the trigger operation for the region associated with the overlay being detected, wherein the trigger operation on the region associated with the overlay is caused by a user and used to control display or undisplay of the overlay.
