Analysis and Improvement of MPEG-DASH-based Internet Live Broadcasting Services in Real-world Environments
Namgi Kim, Byoung-Dai Lee · KSII Transactions on Internet and Information Systems · 2019
Adaptive bitrate streaming is a crucial element in the implementation of high-quality streaming of media content over the Internet.Dynamic adaptive streaming over HTTP (MPEG-DASH) has lately emerged as the de facto solution for over-the-top (OTT) video streaming services.In this paper, we perform macro-level analysis on a real-world MPEG-DASH-based Internet live broadcasting service to gain insight into its behavior throughout the end-to-end service-provision chain, from broadcasters to viewers.Based on this analysis, we propose methods to improve the quality-of-experience (QoE) of MPEG-DASH-based services, particularly with regard to reducing broadcasting delays between recording and viewing of videos, as well as synchronizing client terminals.
