Claim Text:
1. An apparatus comprising a decoding unit configured to decode a data stream, the data stream representing at least one coded image and being stored on a non-transitory computer readable medium, wherein the data stream includes: a plurality of context adaptive entropy encoded sub-streams for a subset of blocks of the at least one coded image, each of the plurality of context adaptive entropy encoded sub-streams including a row of consecutive blocks of quantized coefficients of transformed residual values; wherein, a first context adaptive entropy encoded sub-stream includes a first row of consecutive blocks within a first subset of blocks; a second context adaptive entropy encoded sub-stream includes a second row of consecutive blocks within a second subset of blocks; the second row of consecutive blocks is immediately after the first row of consecutive blocks in a raster order of an image decoded from the coded image; and the second row of consecutive blocks is not immediately after the first row of consecutive blocks in the data stream.
