摘要

在可变比特率(VBR)视频源中，帧中的相邻片之间具有很强的相关性。对于由帧相关表示的帧也是如此。VBR视频源可以通过生成细胞的速率的峰值速率、平均速率和标准偏差进行统计表征。考虑到VBR视频源的各种相关特性和统计特性，通过对所需带宽的估计，可以提高VBR视频源的传输效率。本文提出了一种基于ATM的BISDN中VBR视频源传输带宽的动态预测和分配方案。通过仿真对该方案的性能进行了评价。仿真结果表明，该方案在带宽利用率和小区损失率方面均优于传统方案。

Dynamic bandwidth allocation for VBR video sources in ATM based BISDN

With variable bit rate (VBR) video sources, adjacent slices in a frame are strongly correlated with each other. This is also the case for the frame represented by frame correlation. VBR video sources can be statistically characterized by peak rate, average rate, and standard deviation of the rate of generated cells. Taking account of each correlative and statistical properties, VBR video sources can be more efficiently transmitted by estimating the required bandwidth. In this paper, we propose a scheme that predicts and allocates dynamically transmission bandwidth for VBR video sources in ATM based BISDN. The performance of the proposed scheme is evaluated through simulations. Simulation results show that the proposed scheme is superior to the conventional ones in terms of bandwidth utilization and cell loss rate.<>
