QoE Management in a Video Conferencing Application

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 164)

Abstract

In this paper a framework for managing the QoE for videos encoded with the H.264 codec and transmitted by video conferencing applications through limited bandwidth networks is introduced. We focus our study on the QCIF resolution and medium motion videos, one of the most pervasive video formats used by video conferencing applications across the Internet and cellular systems. Using subjective tests for measuring the level of video quality perceived by end users, we expose the relation between the main influential video parameters and the quality experienced by end users. Further, after investigating the effect of different frame rates and compression levels on video streaming bitrate and consequently on QoE, a QoE control mechanism is proposed for limited-bandwidth cases.
