The Making of Video Quality Standards
The Video Quality
Experts Group (VQEG) determines whether objective video quality
models are accurate enough for industry to trust. ITS helped
establish VQEG in 1997. ITS participates in VQEG by:
- Co-chairing VQEG meetings
- Independent oversight, to promote fairness and accuracy
- Analyzing data from VQEG sponsored subjective tests
- Writing subjective test plans and reports
- Hosting the VQEG website and email lists

The ITU groups responsible for video quality issues are: ITU-T
Study Group 9, ITU-T
Study Group 12 and
ITU-R Working Party 6C.
Within the US, key committees are:
