Abstract

The use of adaptive transmission techniques through HTTP for the reproduction of video services is becoming more and more popular. Currently, there are problems of interoperability due to the large number of devices with different characteristics, which also used different techniques of adaptive transmission. Therefore, telecommunications service providers are looking for alternatives that allow them to support all this diversity of devices and technologies, in order to offer their users higher quality services. In this paper, we present a comparative performance evaluation of the main adaptive streaming techniques for Live Video Streaming services using QoE (Quality of Experience) as the key performance indicator. The study is carried out in an emulated LTE (Long Term Evolution) network composed by real devices (video server and client) interacting with an NS-3 simulated LTE network. We show for the constructed emulation scenario, the technology that presents the best performance in terms of delays and user mobility.

基于QoE度量的LTE网络自适应流技术的比较研究

通过HTTP使用自适应传输技术来复制视频业务正变得越来越流行。目前，由于设备数量众多，特性各异，采用的自适应传输技术也各不相同，因此存在互操作性问题。因此，电信服务提供商正在寻找能够支持所有这些设备和技术多样性的替代方案，以便为用户提供更高质量的服务。在本文中，我们使用QoE(体验质量)作为关键性能指标，对直播视频流媒体服务的主要自适应流媒体技术进行了比较性能评估。该研究是在一个模拟LTE(长期演进)网络中进行的，该网络由真实设备(视频服务器和客户端)与NS-3模拟LTE网络交互组成。对于构建的仿真场景，我们展示了在延迟和用户移动性方面表现最佳性能的技术。
