Quality assessment of streaming services in mobile devices

Abstract

Recently, mobile broadcast services such as DMB, multimedia streaming services and IPTV, caused rapid increase of multimedia services sent over the Internet. It is important to define, measure and evaluate the elements related to the quality of providing the services over the Internet. In this paper, we propose multimedia quality measurement model that evaluates the quality of multimedia from consumers point of view. We selected some parameters that affect the quality of multimedia on application level as well as network level, and then use these parameters to create multiple altered versions of an original video. All videos are then uploaded to YouTube, the popular streaming site. Then each video is viewed by a subject using multiple devices. For each video and device, subjects give Mean Opinion Score (MOS) rating. Then we determined the influence of parameters on videos and devices.
