A Gamma-Based Framework for Modeling Variable-Rate MPEG Video Sources: The GOP GEAR Model
M R. Frey, S Nguyen-Quang
A flexible model called the GOP GBAR 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 GBAR model takes explicit account of MPEG GOP cyclicity and has convenient analytical properties with easily estimated parameters. Possible modifications of the GOP GBAR model are proposed to capture special features of MPEG video.
