DPCM (Differential PCM) A PCM technique that codes the difference between sample points to compress the digital data. Because audio waves propagate in predictable patterns, DPCM predicts the next sample and codes the difference between the prediction and the actual point. The differences are smaller numbers than the numerical value of each sample on the full scale and thereby reduce the resulting bitstream. See PCM, ADPCM and sampling.DPCM (communications) Want to thank TFD for its existence?

DPCM (Differential Pulse Code Modulation): The value of each pixel of an image generally is related to that of adjacent pixels and tends to have a value close to those adjoining it. In order to increase the compression ratio while preserving decent reconstructed image quality, DC coefficients are coded by DPCM and only the most important AC coefficients are coded using classified vector quantization (CVQ). |
