摘要

视频流是一种很有前途的多媒体应用,在无线/移动通信中越来越受欢迎。视频的质量在很大程度上取决于内容的类型。本文的目的有三个方面。首先,利用基于空间(边缘)和时间(运动)特征提取的聚类分析,将视频序列分成代表不同内容类型的组。其次,我们通过实验研究丢包对视频内容的影响,从而找到用户对服务质量感知可接受的上、中、下质量边界的阈值。最后,确定无线网络上不同内容类型的最小发送比特率,以满足服务质量(QoS)要求(例如,达到平均意见评分(MOS)大于3.5的通信质量)。我们测试了12个不同的视频片段,反映了不同的内容类型。我们选择峰值信噪比(PSNR)和可解码帧率(Q)作为端到端视频质量指标,并选择MPEG4作为视频编解码器。这项工作应该有助于优化内容交付网络中特定内容的带宽分配。

Impact of Video Content on Video Quality for Video over Wireless Networks
Video streaming is a promising multimedia application and is gaining popularity over wireless/mobile communications. The quality of the video depends heavily on the type of content. The aim of the paper is threefold. First, video sequences are classified into groups representing different content types using cluster analysis based on the spatial (edges) and temporal (movement) feature extraction. Second, we conducted experiments to investigate the impact of packet loss on video contents and hence find the threshold in terms of upper, medium and lower quality boundary at which users’ perception of service quality is acceptable. Finally, to identify the minimum send bitrate to meet Quality of Serive (QoS) requirements (e.g. to reach communication quality with Mean Opinion Score (MOS) greater than 3.5) for the different content types over wireless networks. We tested 12 different video clips reflecting different content types. We chose Peak-Signal-to-Noise-Ratio (PSNR) and decodable frame rate (Q) as end-to-end video quality metrics and MPEG4 as the video codec. The work should help optimizing bandwidth allocation for specific content in content delivery networks.
