description A wireless video transmission system includes: a coarse compression module to compress a video sub-frame and to generate coarse data of the video sub-frame: a coarse decompression module to generate a coarse sub-frame from the coarse data; an error frame extractor to generate an error sub-frame from the coarse sub-frame and from the video sub-frame; a refinement data encoder to generate a set of transform coefficients from the error sub-frame, and to select a subset of transform coefficients from the set of transform coefficients according to an end-of-block (EOB) indication in the coarse data; and a data combining and modulation module to combine and transmit the coarse data and a refinement data including the subset of transform coefficients.
