Video Quality Experts Group (VQEG)

FRTV Phase I  is the first validation experiment conducted by VQEG.  This test examined Full References (FR) and No Reference (NR) objective video quality models that predicted the quality of standard definition television (625-line and 525-line). Models were submitted in 1999 and VQEG's Final Report was approved June, 2000. All NR models were withdrawn. 

The FRTV Phase I subjective data are included in the final report; and all video sequences are available to researchers. Models that are trained on these datasets must not be compared to the models submitted to VQEG for independent validation in 1999. Such a comparison is misleading, because the experiments contain mainly source scenes and HRCs that were unknown to the model developers

Resulting ITU Recommandations:

The ITU decided that the accuracy of the FR models was not sufficient to justify standardization. FRTV Phase I was a learning experience for VQEG on how to conduct a validation experiment. The validation data had insufficient discrimination power, due to the selection Hypothetical Reference Circuits (HRCs) spanning a narrow range range of quality.
