Abstract :
This paper presents an analysis, simulation, and discussion of the effects of communication errors on four-bit differential pulse-code modulation (DPCM) sampled imagery. Simulations are presented that describe the effects of inserting periodic "PCM updates" in order to correct communication errors in the DPCM transmission of photographic scenes that have been scanned and sampled at the Nyquist rate.
