Abstract

The collaborative nature of opera production offers a unique opportunity to strengthen societal cohesion and empower marginalized voices through storytelling. However, existing live streaming approaches, such as HTTP-Adaptive Streaming (HAS), are not equipped to handle the complexities of co-created opera content, resulting in suboptimal user experiences. To address these limitations, this article introduces the Live Stream Adaptation for Opera (LSAO), a solution designed as part of the EU Horizon 2020 TRACTION project. LSAO is a network-aware adaptive scheme designed to optimize the delivery of live co-created opera performances by dynamically adjusting audiovisual quality based on varying network conditions. Unlike traditional streaming solutions, LSAO prioritizes the unique demands of opera, ensuring seamless delivery and preserving artistic features. The evaluation of LSAO involved an online live opera show featuring four distinct performances by six artists located in globally distributed locations. Delivered to 35 remote viewers across 12 countries and 3 continents, the LSAO system was evaluated based on user feedback on the quality of their streaming experience. The results demonstrate the effectiveness of LSAO in enhancing audio and video quality levels, leading to heightened user enjoyment during live co-created opera performances. Through its approach and successful evaluation, LSAO represents a significant advancement in the delivery of live co-created opera content.

一种实时自适应流媒体解决方案，用于提高共同创作Opera的体验质量

歌剧制作的合作性质为通过讲故事加强社会凝聚力和增强边缘化声音提供了独特的机会。然而，现有的直播方法，如http自适应流媒体（HAS），无法处理共同创建的歌剧内容的复杂性，导致次优用户体验。为了解决这些限制，本文介绍了Live Stream Adaptation for Opera (LSAO)，这是一个作为EU Horizon 2020 TRACTION项目的一部分而设计的解决方案。LSAO是一种网络感知的自适应方案，旨在根据不同的网络条件动态调整视听质量，从而优化现场共创歌剧表演的交付。与传统的流媒体解决方案不同，LSAO优先考虑歌剧的独特需求，确保无缝传输并保留艺术特色。对LSAO的评估涉及一场在线现场歌剧表演，由分布在全球各地的六位艺术家进行四场不同的表演。LSAO系统已交付给3大洲12个国家的35名远程观众，该系统是根据用户对其流媒体体验质量的反馈进行评估的。结果证明了LSAO在提高音频和视频质量水平方面的有效性，从而提高了用户在现场共同创作的歌剧表演中的享受。通过它的方法和成功的评估，LSAO代表了现场共同创作的歌剧内容交付的重大进步。

期刊介绍： The Society’s Field of Interest is “Devices, equipment, techniques and systems related to broadcast technology, including the production, distribution, transmission, and propagation aspects.” In addition to this formal FOI statement, which is used to provide guidance to the Publications Committee in the selection of content, the AdCom has further resolved that “broadcast systems includes all aspects of transmission, propagation, and reception.”
