Abstract:
Online media consumption is the main driving force for the recent growth of the Web. As especially realtime
media is becoming more and more accessible from a wide range of devices, with contrasting screen
resolutions, processing resources and network connectivity, a necessary requirement is providing users with
a seamless multimedia experience at the best possible quality, henceforth being able to adapt to the specific
device and network conditions.
This paper introduces a novel approach for adaptive media streaming in the Web. Despite the pervasive pullbased
designs based on HTTP, this paper builds upon a Web-native push-based approach by which both the
communication and processing overheads are reduced significantly in comparison to the pull-based counterparts.
In order to maintain these properties when enhancing the scheme by adaptation features, a server-side
monitoring and control needs to be developed as a consequence. Such an adaptive push-based media streaming
approach is int
roduced as main contribution of this work. Moreover, the obtained evaluation results provide
the evidence that with an adaptive push-based media delivery, on the one hand, an equivalent quality of experience
can be provided at lower costs than by adopting pull-based media streaming. On the other hand, an
improved responsiveness in switching between quality levels can be obtained at no extra costs.
