ITU-T P.918 PDF

This Recommendation describes a subjective test methodology, which can assess and diagnose the video quality based on underlying perceptual quality dimensions.

Traditional quality tests, as described in [ITU-T P.800] and [ITU-T P.910], provide valid methods for the overall video quality but do not give insights into reasons for possible quality losses.

This Recommendation describes a test methodology that not only yields overall quality scores for video but specifically allows participants to rate five underlying perceptual quality dimensions for video and video transmission in general. The perception-based assessment of video QoE is important when planning and implementing services, as well as for the development of instrumental quality prediction models, especially when the service on hand is aimed for usage by humans.
