Abstract
AbstractA variable segmentation scheme based on intrinsic video rate characteristics (VSIVRC) is proposed for efficient dynamic bandwidth allocation to transport pre‐stored variable bit rate (VBR) video across networks. The proposed scheme is evaluated with a set of real‐life MPEG video traces and also compared with two fixed segmentation schemes: equal data segmentation (EDS) and equal frame segmentation (EFS). The obtained results show that the proposed VSIVRC scheme significantly outperforms both EDS and EFS in terms of range of selective bandwidth, matchness between arrival stream and playback stream, buffer occupancy and bandwidth allocation as well.
