摘要
动态自适应HTTP流(Dynamic Adaptive Streaming over HTTP, DASH)是一种为自适应多媒体传输而设计的标准。本文介绍了一种自适应多媒体和多媒体传输系统,该系统采用DASH扩展来支持多种感知媒体。使用现实生活测试平台的测试表明,当采用将用户暴露于多感官内容的建议解决方案时,用户满意度如何提高。这项工作背后的动机是创造远程自适应多感官媒体(多媒体)内容交付的第一个解决方案,以提高用户满意度并提高他们的体验质量。建立并测试了基于dash的多媒体传输系统(DASH-MS)。这项工作的重点是远程多感官媒体系统的一个基本问题:同步,并展示了拟议的DASH-MS如何解决这个问题。现实生活主观测试的结果表明,当用户接触到具有多媒体效果的内容时,用户满意度的平均水平更好,或者至少等于那些没有包含此类效果的内容。此外,满意度的最高值与这些效果正确同步的情况相对应。最后,用户似乎更喜欢提前效果而不是后期效果。
A DASH-based Mulsemedia Adaptive Delivery Solution
The Dynamic Adaptive Streaming over HTTP (DASH) is a standard designed for adaptive multimedia delivery. This paper describes an adaptive multimedia and mulsemedia delivery system which employs an extension of DASH to support multiple sensorial media. Testing using a real-life test-bed shows how user satisfaction increases when employing the proposed solution which exposes users to multi-sensorial content. The motivation behind this work is the creation the first solution for remote adaptive multi-sensory media (mulsemedia) content delivery in order to enhance user satisfaction and increase their quality of experience. A DASH-based mulsemedia delivery system (DASH-MS) was built and tested. This work focuses on a fundamental issue for remote multi-sensory media systems: synchronization and shows how the proposed DASH-MS addresses it. Results of real life subjective testing indicate that the average levels of user satisfaction when exposed to content with the mulsemedia effects are better or at least equal to those when no such effects were included. Additionally, the highest value of the level of satisfaction corresponds to the case when these effects were correctly synchronized. Finally, users seem to have preferred effects in advance than late effects.
