Abstract
An apparatus for encoding an image. In one embodiment, the apparatus comprises a hash function module for determining changes to a plurality of scan blocks of an image; an encoder module, coupled to the hash function module, for encoding each scan block in the plurality of scan blocks as layers of increasing quality; and selecting specific scan blocks having a specific quality layer for transmission in response to the hash function module change determination.
