摘要：
We propose a packet dropping algorithm for various packet loss rates. A network-based packet loss visibility model is used to evaluate the visual importance of each H.264 packet inside the network. During network congestion, based on the estimated loss visibility of each packet, we drop the least visible frames and/or the least visible packets until the required bit reduction rate is achieved. Based on a computable perceptually-based metric, our algorithm performs better than an existing approach (dropping B packets or frames).
