Summary:In this work we present an end-to-end optimized video streaming
system comprising of synergistic interaction between a source
packetization strategy and an efficient and responsive, TCP-friendly
congestion control protocol [Linear Increase Multiplicative Decrease
with History (LIMD/H)]. The proposed source packetization scheme
transforms a scalable/layered video bitstream so as to provide graceful
resilience to network packet drops. The congestion control mechanism
provides low variation in transmission rate in steady state and at the
same time is reactive and provably TCP-friendly. While the two
constituent algorithms identified above are novel in their own right, a
key aspect of this work is the integration of these algorithms in a
simple yet effective framework. This “application-transport”
layer interaction approach is used to maximize the expected delivered
video quality at the receiver. The integrated framework allows our
system to gracefully tolerate and quickly react to sudden changes in the
available connection capacity due to the onset of congestion, as
verified in our simulations
