Abstract
To facilitate the recovery data from an embedded data pattern through the use of a appropriately sized capture window that is randomly positioned within the data pattern, the embedded data pattern is composed of a plurality of identical, one dimensionally or two dimensionally regularly tiled embedded data blocks which contain sufficient spatial addressing information to permit the logical reconstruction of a complete data block from any set of fragments that collectively provide a full cover for the surface area of any one tile. To this end, the capture window is sized to include a shape which is completely registered with the data pattern in which is capable of tiling the recording medium in accordance with the tiling vectors.
