Nicola J Fedele, Alfonse A Acampora: DPCM system with rate-of-fill control of buffer occupancy. RCA Corporation, Allen LeRoy Limberg Henry I Steckler William H Meise, November 10, 1987: US04706260 (87 worldwide citation)

In a differential pulse code modulator for image-representative signals, a coder codes difference signals to produce coded signals which have a highly variable rate, which depends upon motion in the image being represented. A rate buffer receives the coded signals and generates a control signal repr ...
