ENVISION中SVC流的PDKEEPAAA评估
QoE assessment for SVC streaming in ENVISION
摘要：
可伸缩视频编码由于其能够处理终端异构性和网络条件变化的能力，在许多多媒体服务中的内容交付中引起了极大的兴趣。在我们以前的工作中，在EXPERISION的保护下，我们提出了一种播放平滑机制，通过减少流在适应不断变化的网络条件时所经历的质量变化来确保分层流的均匀交付。在本文中，我们研究由此产生的视频质量，从最终用户的感知在不同的网络条件下的损失和延迟。因此，我们采用了双重刺激损害量表（DSIS）方法。结果表明，在不同的网络配置下，平滑的视频片段的平均意见得分较高。这证实了所提出的平滑机制的有效性。
英文摘要：
Scalable video coding has drawn great interest in content delivery in many multimedia services thanks to its capability to handle terminal heterogeneity and network conditions variation. In our previous work, and under the umbrella of ENVISION, we have proposed a playout smoothing mechanism to ensure the uniform delivery of the layered stream, by reducing the quality changes that the stream undergoes when adapting to changing network conditions. In this paper we study the resulting video quality, from the final user perception under different network conditions of loss and delays. For that we have adopted the Double Stimulus Impairment Scale (DSIS) method. The results show that the Mean Opinion Score for the smoothed video clips was higher under different network configuration. This confirms the effectiveness of the proposed smoothing mechanism.
