Abstract

Basic characteristics of variable-rate video coders applied to asynchronous transfer mode (ATM) transmision are described. Burstiness of video information is evaluated for conference-type scenes using various coding algorithms. Three measures (distribution, autocorrelation, and coefficient of variation) are introduced to evaluate burstiness. Video sources are modeled and characterized by the autoregressive process and coefficient of variation. Video quality improvement achieved with variable rate transmission is evaluated using signal-to-noise ratio (SNR) and subjective ratings. An improvement of 5-10 dB in temporal SNR and 1 rank in mean opinion score are reported.
