The popularity of 3D videos increased significantly in recent years. Transfering of 3D contents over the Internet is a big challenge for Internet Service Providers because to ensure proper quality of service is important for customers’ perceived quality of experience.

The main goal of my thesis was to introduce the relation between the quality of service (QoS) and the quality of experience (QoE) and to evaluate the nature of this relation by means of an appropriate statistical tool.

I was supposed to summarize 3D technologies and video-codings available nowadays. I introduced terms of QoS and QoE as well as the factors influencing them and the theoretical realtionship between them. In addition, I also showed the proper way of statistical analysis.

It was necessary to measure the quality of experience based on the quality of service degradation and to determine the relation between the QoS and QoE based on the results. QoE measurements were also performed by changing of the quality of 3D video-coding. To achieve the purpose of my assignment it was necessary to transfer 3D video-streams over a network. It was accomplished by a Gigabit Passive Optical Network (GPON) in the laboratory of the department. Measurements of quality of experience of the 3D video-streams were made by subjective methods.

The results of the measurements were processed by IBM SPSS Statistics software. My main objective was to summarize the results clearly and to show the relation between each measurement and finally to provide graphical representation of the relation between QoS and QoE.

My thesis is usable for planning and implementing quality of experience measurements as well as giving guidance to perform a statistical treatment for subjective measurements. Those who are interested in this theme can get acquainted with the relation between QoS and QoE of 3D video streams.
