Throughput and delay analysis in video streaming over block-fading channels

In a streaming application video packets are required to be decoded and displayed in the order they are transmitted as the transmission continues. This results in perpacket delay constraints, and in the wireless setting the resulting channel can be modeled as a physically degraded fading broadcast channel with as many virtual users as the number of packets. Two important quality of user experience (QoE) metrics, throughput and inter-decoding delay, are considered jointly, and lower and upper bounds on both metrics are presented. © 2013 IEEE.
