Noun
DPCM (uncountable)
Initialism of differential pulse-code modulation.
An example of an encoded 8x8 FDCT block: : Since the DC coefficient value is statistically correlated from one block to the next, it is compressed using DPCM encoding. Source: Internet
DM is the simplest form of differential pulse-code modulation (DPCM) where the difference between successive samples are encoded into n-bit data streams. Source: Internet
The DC coefficients and motion vectors are DPCM -encoded. Source: Internet
Well-known schemes for lossless coding of continuous-tone images can be applied, achieving somewhat better compression than the Huffman coded DPCM used in JPEG. Source: Internet
