Abstract
The authors characterize variable-rate interframe video coding for an ATM (asynchronous transfer mode) -based environment, focusing on bursty characteristics of encoded information. Inter-frame DPCM (differential pulse code modulation), motion-compensated DPCM and motion-compensated DCT (discrete cosine transform) are examined. As a useful measure to characterize variable-rate video sources, the coefficient of variation is proposed to supplement conventional distribution and autocovariance. Modeling methods variable-rate coders using the AR (autoregressive) process and coefficients of variation are introduced. The fitness of each model is evaluated by estimating stochastic multiplexing effects for a simple one-buffer one-server situation.
