摘要

在本文中，我们提出并评估了两种新的MPEG-4 AVC视频流量模型的准确性。第一个预测了MPEG-4 AVC压缩视频的b帧大小。第二个预测了MPEG-4 AVC压缩视频的图片组(GOP)的大小。我们还提出了使用新的场景变化检测器度量来增强这些模型。这些流量模型可以被网络调度程序用来有效地提供MPEG-4 AVC视频带宽。

High-Definition MPEG-4 AVC Traffic Analysis and Bandwidth Prediction

In this paper, we propose and evaluate the accuracy of two new MPEG-4 AVC video traffic models. The first predicts the size of the B-frames of MPEG-4 AVC compressed video. The second predicts the size of the group of pictures (GOP) of the MPEG-4 AVC compressed video. We also propose an enhancement to these models using a new scene change detector metric. These traffic models can be employed by a network scheduler to provision MPEG-4 AVC video bandwidth efficiently.
