Abstract

A flexible model called the group-of-pictures gamma-beta auto-regression (GOP GBAR) model based on gamma-distributed variables is proposed for variable-rate MPEG video sources. This model is an extension of Heyman´s (see IEEE/ACM Trans. Networking, vol.5, p.554-60, 1997) GBAR model for video teleconferencing. The GOP GBAR model explicitly accounts for MPEG GOP cyclicity and has convenient analytical properties with easily estimated parameters. Possible extensions of the GOP GBAR model are proposed to capture special features of MPEG video
