Exploring Temporal Loss Tolerance of Video Codecs for QoE Enhancement in Adaptive Streaming

Video streaming is not only for entertainment now, but also for lessons, communications, meetings, and even diagnosis. Quality of Experience (QoE) is the most important concerned aspect by content providers and platform providers. Among all the experience, enduring stalls is the most frustrating one. In this thesis, we present Bandwidth-Efficient Temporal Adaptation (BETA) and Temporal Adaptive Streaming over QUIC (TASQ), whose target is to improve the smoothness of video playbacks even under extreme network conditions. We investigate temporal loss tolerance for HEVC and AV1, and apply the optimization on video streaming. Results show a drastic improvement on the smoothness and the QoE.
