摘要：Methods and arrangements are provided for compressing, transporting anddecompressing/rendering concentric mosaic image data. The methods and arrangementscompress concentric mosaic image data using reference block coding (RBC) techniques.
Such RBC techniques selectively divide each of the frames of the concentric mosaic imagedata into blocks, and then predictively encodes each of these blocks. Some of the blocksare independently encoded as anchor blocks. Each of the remaining blocks is encoded asa predicted block with motion compensation to the anchor frame. The resultingcompressed data file includes indexing information that can be used to selectively,randomly access the compressed data during decompression/rendering. A bitstream canbe selectively tailored to provide portions of the compressed data file, as needed, forexample, during rendering of a particular user-selected view of the concentric mosaicimage scene.
