Реферат: A method of content compression including receiving a first block of samples including at least a first sample and a second sample, calculating a predictor value for the first block of samples, calculating a residual between the predictor value and the first sample, quantizing the residual to generate a quantized residual, de-quantizing the quantized residual to generate a de-quantized residual, reconstructing the first sample using the de-quantized residual and the predictor value to generate a first reconstructed sample, calculating an error value based on the first sample and the first reconstructed sample, and modifying the second sample by the error value.
