TCP is Bottleneck of Video Streaming via OTT

Abstract

Video Services using Over-The-Top (OTT) becomes extremely popular in all countries but video streaming through unguaranteed path in Internet cause a lot of problems to keep the Quality of Experience (QoE) on a suitable level. In the previous works of research, the influence of Quality of Service (QoS) parameters on re-buffering effect were done. Here we continue this research for video with higher resolution 1080p, 2K or also 4K. The primary purpose of this research is to investigate how delay and packet loss influence on re-buffering effect in HLS, RTMP and MPEG-DASH streaming protocols delivering high resolution video.
