Enhancement of Video Streaming QoE by Considering Burst Loss in Wireless LANs

抄録

In order to enhance QoE of audio and video IP transmission, this paper proposes a method for mitigating the spatial quality impairment during burst loss periods over the wireless networks in the video output scheme SCS, which is a QoE-based video output scheme. SCS switches between two common video output schemes: frame skipping and error concealment. The proposed method pauses video output with an undamaged frame during the burst loss period in order not to pause video output on a degraded frame. We perform an experiment with constant thresholds, the table-lookup method, and the proposed method under various network conditions. The result shows that the effect of the proposed method on QoE can differ with the contents and GOP structures.
