Abstract
A quantized subset of set of image data is obtained. One or more iterations of inverse quantization are performed on the quantized subset until a de-quantized subset is produced that meets specified criteria. A block of an image frame is determined based at least in part on the de-quantized subset. The block is stored in a region of the memory allocated for storage of the block. A set of blocks that includes the block is output from the memory.
