Abstract
Embedded differential pulse code modulation (DPCM) is performed in response to coding locations of DPCM non-zero residuals during entropy coding utilizing adaptive run-length (ARL) coding. In this manner the need to code zero residuals is eliminated. After adaptive run-length coding, the non-zero residuals are coded in the regular mode, such as utilizing exponential Golomb coding. Overall compression is improved for blocks containing any significant number of zeros.
