abstract = "Live video streaming has seen tremendous growth in the
past decade. An important fact in live streaming is
that the demand for low playback-latency inherently
conflicts with the desire for high QoE. This requires
different types of live services to seek different
latency-QoE tradeoffs according to their
service-requirements. However, our investigations
revealed that it is fundamentally difficult for
existing streaming algorithms to keep consistent
latency in changing network conditions, let alone
achieve the service-desired latency-QoE tradeoff. To
tackle the challenge, this article develops a novel
framework called Flexible Latency Aware Streaming
(FLAS) that not only can achieve consistent low
latency, but also control the latency-QoE tradeoff
flexibly. Specifically, FLAS generates a set of
adaptation logics offline, each optimized for a
candidate tradeoff point, then selects the most
appropriate one to run online. We first show how FLAS
can be applied to optimizing the existing algorithms,
then developed a novel Genetic Programming approach to
fully exploit FLAS's potential. Extensive evaluations
show that FLAS can precisely control latency all the
way down to 1s and achieve substantially higher QoE
than state-of-the-arts. FLAS can be readily implemented
into real streaming platforms, offering a practical and
reliable solution for live-streaming services.",
