什么是适应逻辑?基于HTTP的自适应流媒体系统的主客观性能评估

Which Adaptation Logic? An Objective and Subjective Performance Evaluation of HTTP-based Adaptive Media Streaming Systems

Christian Timmerer, Matteo Maiero, Benjamin Rainer

摘要:

互联网上的多媒体内容传输主要使用超文本传输协议(HTTP)作为其主要协议,并且存在多种专有解决方案。MPEG标准HTTP动态自适应流传输(DASH)提供了可互操作的解决方案,并且近年来已经提出了各种自适应逻辑/算法。然而,据我们所知,没有对各种逻辑/算法进行全面评估。因此,本文提供了十个不同的自适应逻辑/算法,在过去几年中提出了一个全面的评价。评价是客观和主观的。前者在受控环境中使用预定义的带宽轨迹,后者在现实环境中采用众包完成。结果将提供有关在实际部署场景中可以采用哪种策略的见解。此外,本文中描述的评估方法可用于评估任何其他/新的自适应逻辑,并将其直接与本文报告的结果进行比较。

英文摘要:

Multimedia content delivery over the Internet is predominantly using the Hypertext Transfer Protocol (HTTP) as its primary protocol and multiple proprietary solutions exits. The MPEG standard Dynamic Adaptive Streaming over HTTP (DASH) provides an interoperable solution and in recent years various adaptation logics/algorithms have been proposed. However, to the best of our knowledge, there is no comprehensive evaluation of the various logics/algorithms. Therefore, this paper provides a comprehensive evaluation of ten different adaptation logics/algorithms, which have been proposed in the past years. The evaluation is done both objectively and subjectively. The former is using a predefined bandwidth trajectory within a controlled environment and the latter is done in a real-world environment adopting crowdsourcing. The results shall provide insights about which strategy can be adopted in actual deployment scenarios. Additionally, the evaluation methodology described in this paper can be used to evaluate any other/new adaptation logic and to compare it directly with the results reported here.
