| description | We take an analytical approach to study Quality of
user Experience (QoE) for video streaming applications. First,
we show that random linear network coding applied to blocks of
video frames can significantly simplify the packet requests at the
network layer and save resources by avoiding duplicate packet
reception. Network coding allows us to model the receiver’s buffer
as a queue with Poisson arrivals and deterministic departures.
We consider the probability of interruption in video playback as
well as the number of initially buffered packets (initial waiting
time) as the QoE metrics. We characterize the optimal trade-off
between these metrics by providing upper and lower bounds on
the minimum initial buffer size, required to achieve certain level
of interruption probability for different regimes of the system
parameters. Our bounds are asymptotically tight as the file size
goes to infinity. |
