The apparatus (300) comprises a DWT engine (308), a code block manager (310) and entropy encoder (314). The code block manager (310) comprises at least one controller (412, 414, and 416), which losslessly compress the transform coefficients and stores them in a code block store (418) for buffering. The entropy coder (314) comprises at least one entropy encoder (422, 424, 426), each comprising a decoder (1206, 1204,) for decoding the losslessly compressed transformed coefficients prior to entropy encoding (1202).
