Subjective Video Quality Test Standards
The International
Telecommunications Union
(ITU) creates Recommendations (standards) that
describe how subjective video quality experiments should
be performed. Key Recommendations are:
- ITU-R Rec.
BT.500 - a highly controlled environmentvideo for rating
the video quality of
broadcast television signals. The intention
is that environmental variables cannot influence people's opinion
(e.g., lighting, background noise, wall decorations, wall color,
distance to screen).
- ITU-T Rec.
P.910 - a controlled environment for rating the
video quality of multimedia services such
as videotelephony, videoconferencing and video-on-demand.
- ITU-T Rec.
P.911 - combines P.910 and P.800, to provide
audiovisual quality ratings.
- ITU-T Rec.
P.912 - analyzes whether or not a video link can be used for a
specific task, such as reading license
plates.
- Proposed new Recommendation: Draft ITU-T Rec.
J.av-dist "Methods for subjectively assessing
audiovisual quality of internet video and distribution quality
television, including separate assessment of video quality and
audio quality".
