Abstract

The paper describes experimental study of Quality of Experience of compressed audiovisual materials when the bandwidth available is changing. We propose a model of QoE multimodal assessment for audiovisual programs of various contents and in a wide range of compressed video and audio data bitrates. On the basis of the model an optimization problem of audio and video bit rate allocation in bandwidth-limited systems can be solved. The approach proposed is based on a cross-modal audiovisual interaction and takes into account that optimal audio and video codec parameters in bandwidth-limited multimedia systems can be content-adaptive.

自适应比特率视频流压缩材料的多模态质量评估
本文对可用带宽发生变化时压缩视听材料的体验质量进行了实验研究。我们提出了一个多模态QoE评估模型,用于各种内容的视听节目和在大范围的压缩视频和音频数据比特率。在此模型的基础上,可以解决带宽有限的系统中音视频比特率分配的优化问题。该方法基于跨模态视听交互,并考虑到带宽有限的多媒体系统中最优音视频编解码器参数可以自适应内容。
