Abstract
Various aspects of a system and method for block-based compression of digital content are disclosed herein. The method comprises quantization, by an encoder, of each block of a plurality of blocks of a digital content based on a computed quantization value. A differential pulse code modulation (DPCM) is computed, by the encoder, to generate quantized residuals of the quantized plurality of blocks. Entropy coding on each of the quantized plurality of blocks is performed by the encoder based on the generated quantized residuals. A compressed bitstream of the digital content is generated by the encoder. The compressed bitstream that comprises depth-first refinement of the entropy-coded quantized plurality of blocks, is generated.
