Fine Granularity Adaptive Multi-Receiver Video Streaming
In: Fourteenth annual Conference on Multimedia Computing and Networking (MMCN07), ed. by Roger Zimmermann and Carsten Griwodz, SPIE
Efficient delivery of video data over computer networks has been
studied extensively for decades. Still, multi-receiver video delivery
is challenging, due to heterogeneity and variability in network
availability, end node capabilities, and receiver preferences. Our
earlier work has shown that content-based networking is a viable
technology for fine granularity multi-receiver video streaming. By
exploiting this technology, we have demonstrated that each video
receiver is provided with fine grained and independent selectivity
along the different video quality dimensions region of interest,
signal to noise ratio for the luminance and the chrominance planes,
and temporal resolution. Here we propose a novel adaptation scheme
combining such video streaming with state-of-the-art techniques from
the field of adaptation to provide receiver-driven multi-dimensional
adaptive video streaming. The scheme allows each client to
individually adapt the quality of the received video according to its
currently available resources and own preferences. The proposed
adaptation scheme is validated experimentally. The results demonstrate
adaptation to variations in available bandwidth and CPU resources
roughly over two orders of magnitude and that fine grained adaptation
is feasible given radically different user preferences.
