Dynamic resolution switching for live streaming
Xin Xiong, Yixu Chen, Hai Wei +2
Conventional adaptive bitrate (ABR) streaming systems typically rely on static bitrate ladders to optimize Quality of Experience (QoE). While operationally simple, this "one-size-f…

This paper reports IEEE International Conference on Multimedia \& Expo (ICME) 2025 Grand Challenge on Generalizable HDR and SDR Video Quality Measurement. With the rapid developmen…
HDRSDR-VQA: A Subjective Video Quality Dataset for HDR and SDR Comparative Evaluation
Bowen Chen, Cheng-han Lee, Yixu Chen +3
We introduce HDRSDR-VQA, a large-scale video quality assessment dataset designed to facilitate comparative analysis between High Dynamic Range (HDR) and Standard Dynamic Range (SDR…
Video Quality Assessment for Resolution Cross-Over in Live Sports
Jingwen Zhu, Yixu Chen, Hai Wei +2
In adaptive bitrate streaming, resolution cross-over refers to the point on the convex hull where the encoding resolution should switch to achieve better quality. Accurate cross-ov…
