A method of encapsulating an encoded bitstream representing one or more images, the method comprising: providing tile description information comprising spatial parameters for dividing an image area into one or more tiles; providing tile picture item information identifying a portion of the bitstream representing a tile of a single image; providing reference information linking said tile picture item to said tile description information, and outputting said bitstream together with said provided information as an encapsulated data file. Embodiments of the invention make it possible to easily identify, select and extract tiles from images by parsing syntax elements and without complex computation. |
