如今，HTTP自适应流（HAS）已经成为一种可靠的分发技术，在用户感知的体验质量（QoE）和内容和网络服务提供商的资源利用方面提供显著的优势。通过权衡视频质量，HAS能够适应可用带宽和显示要求，以便它可以通过互联网将视频内容传送到各种设备。然而，到目前为止，还没有足够的知识如何适应技术影响最终用户的视觉体验。因此，本文提出了一种不同的比特率自适应流的单视场和立体视频的策略进行了比较分析。这是通过测试最终用户对视频质量变化的响应的主观实验来完成的，考虑到视觉舒适性问题。实验结果对不同适应策略的用户体验质量的影响因素有了很好的了解。
Nowadays, HTTP adaptive streaming (HAS) has become a reliable distribution technology offering significant advantages in terms of both user perceived Quality of Experience (QoE) and resource utilization for content and network service providers. By trading-off the video quality, HAS is able to adapt to the available bandwidth and display requirements so that it can deliver the video content to a variety of devices over the Internet. However, until now there is not enough knowledge of how the adaptation techniques affect the end user's visual experience. Therefore, this paper presents a comparative analysis of different bitrate adaptation strategies in adaptive streaming of monoscopic and stereoscopic video. This has been done through a subjective experiment of testing the end-user response to the video quality variations, considering the visual comfort issue. The experimental outcomes have made a good insight into the factors that can influence on the QoE of different adaptation strategies.
