Claim 11:
12. A method of forming a bitstream by a video encoder apparatus comprising:
encoding, by the encoder apparatus, media data of one or more video tiles for an output video frame into a plurality of bitstream parts, each one of the bitstream parts being associated with a different one of the video tiles and each one of the one or more video tiles being associated with a tile identifier;
determining, by the encoder apparatus, tile positioning information comprising the tile identifiers of the one or more video tiles and one or more boundary identifiers associated with each video tile of the one or more video tiles,
wherein the tile identifiers and boundary identifiers determine a tile map defining a spatial layout of the one or more video tiles in the output video frame,
and wherein a position of a given video tile relative to that of at least one more other given video tile is specified, without reference to coordinates of a coordinate system, by a predetermined relation between one or more boundary identifiers of the given video tile and one or more other boundary identifiers of the at least one more other given video tile; and

forming, by the encoder apparatus, the bitstream, the bitstream comprising the plurality of bitstream parts representing the encoded media data of the one or more video tiles and tile positioning information associated with the one or more video tiles, the tile positioning information being embedded in the bitstream by the encoder apparatus.
