The document proposes a receiver-driven adaptive layer switching algorithm for scalable video transmission over variable bandwidth networks. The algorithm relies on an estimator at the receiver to trigger adjustments to the number of video layers sent by the source based on available throughput without prior knowledge of channel qualities. Simulations show the algorithm can accommodate different channel qualities efficiently.

1. RECEIVER-DRIVEN ADAPTIVE ENHANCEMENT LAYER SWITCHING ALGORITHM FOR
SCALABLE VIDEO TRANSMISSION OVER LINK-ADAPTIVE NETWORKS
ABSTRACT:
A receiver-driven adaptive layer switching algorithm is proposed for adapting the video bitrate to
match the achievable network throughput. It relies on aQoS-constrained equivalent bandwidth
estimator employed at the receiver, which is used for triggering the adjustment of video layers at
the video source. Simulations are conducted to illustrate its efficiency by showing that it is
capable of accommodating different channel qualities without their prior knowledge.
