摘要

本文提供了一种为包含流媒体内容的多元学习平台提供 QOE 增强功能的方法。我们演示了如何利用 Lighthouse 工具增强多元平台的 QOE。在 Lighthouse 工具的帮助下,页面加载速度提高了 75%。我们还演示了如何利用 CMAF 格式的 DASH 内容提高视频流内容的播放质量。与单比特率媒体相比,基于 DASH 的媒体可提供更好的视频播放质量。研究还评估了学习者对学习平台特定互动功能的偏好。最不喜欢的功能是静态内容。这项研究的结果提供了经验数据,有助于教学设计人员在经验数据的指导下选择功能,并改善教学学习平台的 QOE。

An Interactive Multimedia Model for Developing QOE-Enhanced E-Learning Platforms
This paper provides an approach to providing QOE enhancement for a multifaceted learning platform that includes streamed media content. We demonstrate how the QOE of a multifaceted platform can be enhanced using the Lighthouse tool. The Lighthouse tool helped improve the page load speed by 75%. We also demonstrate how the playback quality of the video streaming content can be enhanced using CMAF-formatted DASH content. When compared to single-bit rate media, DASH-based media provided better video playback quality. The study also evaluates the learners` preferences for specific interactive features of a learning platform. The least preferred feature uniquely had static content. The results of this study provide empirical data that would help instructional designers make feature selection choices that`s guided by empirical data and improve the QOE of their instructional learning platforms.
