1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform:
define or extend a file format data structure for a mask item to comprise:
a cell size to indicate dimensions of a region, in pixels, wherein the region is represented by a mask value;
a mask coding method to indicate a coding method applied to a particular area of a media, wherein the region maps to the particular area of the media, wherein the mask coding method is represented by a mask coding method value;
one or more mask coding parameters to indicate additional encoding or decoding parameters needed to process the particular area of the media; and
a mask configuration for the mask item comprising mask related information as a mask configuration structure.
