QoE Evaluation for Live Broadcasting Video

The great variations of videographic skills in shot environment, photographic apparatus, compression and processing protocols give rise to very complicated impairments in the live broadcasting videos, which can adversely impact the quality of experience (QoE) of end users. Evaluating QoE of these videos is of great significance. Given the fact that there is still no publicly available database that studies the combined effects of the distortions in the live broadcasting videos, we have built the Live Broadcasting Video Database (LBVD) with the associated QoE scores. Towards depicting the distortions in live broadcasting videos, totally 1013 videos were included in the database, with diversified, authentic distortions. A subjective evaluation of these videos is conducted, and the correlation results between the tested state-of-the-art objective metrics and the subjective QoE scores on this database reveal that further studies are in urgent need for a better objective QoE metric dedicated to the live broadcasting videos.
