On Smoothing Algorithms for Transmission of Stored MPEG Video

In this paper, we consider smoothing algorithms in delivering stored varied-bit-rate (VBR) MPEG video over high-speed network. The required network bandwidth of a video service significantly affects its cost. Video smoothing techniques promise reduced bandwidth variablity and consequently reduced bandwidth requirement. Because of varying frame size, MPEG video introduces burstiness during transmission, when left unalleviated, will affect network management and resource utilization. Various smoothing algorithms have been proposed to tackle bursty transmissions, giving optimal transmission schedules under various constraints. The first part of the paper gives a survey of the state-of-art smoothing algorithms for stored VBR videos. In the second part of the paper our work on satisfying each video bandwidth request under limited available bandwidth
