An MPEG-DASH Methodology for QoE-Aware Web3D Streaming

Recent advances in web technologies have now created a ubiquitous environment for cross-platform and cross-device multimedia applications. Media files can now be reproduced in a wide range of devices, from mobile phones to desktop computers and web-enabled televisions, using a common infrastructure. This trend towards unifying the technological infrastructure, however, has given rise to a new array of problems resulting from the varying technological capabilities of the different devices and environments. This paper, proposes an adaptive streaming framework for the display of 3D models on a wide range of web-enabled devices. The open, XML-based X3D language for 3D graphics is combined with the MPEG-DASH standard for adaptive streaming. The end result is a framework that can adaptively display 3D graphics in the face of network or computational limitations, and dynamically adapt data flow to maximize user Quality of Experience in any situation.
