Suitability of Transport Techniques for Video Transmission in IP Networks

The paper discusses the problem of video transmission in an IP network. authors consider ability using most popular codecs that use both MPEG2 Transport Stream and Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH). main emphasis was given to ensuring quality service assessment methods, taking into account not only service- or network provider’s point view but also end user’s perspective. Two approaches were presented, i.e. objective subjective methods. presented results evaluation for H.264/MPEG-4, H.265/HEVC VP9 codecs. measurements, proved by statistical analysis user opinion scores, confirmed H.265 real time streaming transmissions, while HTTP with H.264 codec inadequate. a connection between dynamics bandwidth changing MPEG-DASH mechanism operation their influence on experienced users.
