- Abstract
Video services are becoming more and more popular for mobile network users and require greater and greater resources and provisions from telecommunications service providers. But operators suffer from problems of interoperability between the different adaptive transmissions techniques they employ in an attempt to satisfy the quality of experience (QoE) of the service provided to users and improve network performance. This article presents a comparison of four such streaming techniques - DASH (dynamic adaptive streaming over HTTP), HDS (HTTP dynamic streaming), HLS (HTTP2 live streaming) and HSS (HTTP smooth streaming) - used in a live video playback by a user in different test scenarios on an emulated long-term evolution (LTE) network. Comparison of performance was carried out using the mean opinion score (MOS) metric calculated based on ITU-T Recommendation P.1203. This recommendation focuses on bitstream-based parametric quality assessment of progressive downloads and adaptive audiovisual streaming services through a reliable transport protocol. From the results obtained in the evaluation of the different adaptive transmission techniques for the test scenarios presented, it is observed that the DASH protocol presented a better performance in the QoE evaluation using the MOS metric compared to the other protocols analyzed.
