Implementation of QoE Model Based on Pixel Density

Abstract

Dynamic Adaptive Streaming over HTTP popular known as DASH is a standard developed by ISO/IEC MPEG. DASH implements the convenient and smooth transmission of video streams over heterogeneous end user devices over the IP network with limited bandwidth. Device screen size, design layout and resolution are some of the device context parameters which impact video quality on mobile devices. This paper presents the implementation and the application of the new proposed model over DASH by using an open source libdash library. The implementation has shown that the proposed model performs better than the default Libdash quality adaptation in terms of average stalling numbers and average stalling time.
