摘要：
A flexible model called the group-of-pictures gamma-beta auto-regression (GOP GEAR) model based on Gamma-distributed variables is proposed for variable-rate MPEG video sources. This model is an extension of Heyman's GBAR model for video teleconferencing, The GOP GEAR model explicitly accounts for MPEG GOP cyclicity and has convenient analytical properties with easily estimated parameters. Possible extensions of the GOP GEAR model are proposed to capture special features of MPEG video.
