1. A method performed by a server device for handling media data streams, the method comprising:
obtaining multiple streams of source media data of varying resolution each having multiple source frames, wherein each source frame is divided into a plurality of tiles;
selecting a subset of tiles from at least two of the multiple streams of source media data, wherein the selected subset of tiles is comprised in an output frame, wherein the selected subset of tiles varies in scale and resolution, wherein selecting the subset of tiles is based on user gaze information and allocated bandwidth; and
determining layout information for the selected subset of tiles in the output frame, wherein the layout information comprises scale, source tile index and output tile index.
