Leaky-bucket based rate control algorithm for C_VBRvideo encoding

Yunpeng Bai, Liao, Lin

Open publisher page 3 citations

Abstract

A rate control algorithm is presented for constrained variable bit rate (C_VBR) encoding to make the compressed video stream more friendly to the user network interface (UNI) than in free VBR coding. Experiments show that the algorithm would not only meet the delay constraint and traffic contract of VBR transfer so as to avoid the cell loss over UNI, but also benefit the statistical multiplexing by reducing the burstiness of the MPEG encoded stream.
