Claim 13:
14. A video encoding apparatus comprising:
a computer readable storage medium having at least part of a program embodied therewith; and
a computer readable storage medium having computer readable program code embodied therewith, and a processor coupled to the computer readable storage medium, wherein responsive to executing the computer readable program code, the processor is configured to perform executable operations comprising:
encoding 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 a tile map representing a spatial layout of the one or more video tiles by associating each video tile with a position in the output video frame;
determining 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 boundary identifiers are configured to identify neighboring video tiles in the tile map,
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 a bitstream, the bitstream comprising the plurality of bitstream parts representing the encoded media data of video tiles and tile positioning information associated with the video tiles, the tile positioning information being embedded in the bitstream by the encoder apparatus.
