Unfortunately, such an approach requires the additional nonlinear mapping with the regression function according to VQEG recommendation [31].

Presently this model has 4 different flavors: Video Quality Expert Group (VQEG) Proponent A (NTT, Japan), VQEG Proponent B (OPTICOM, Germany), VQEG Proponent C (Psytechnics, UK), and VQEG Proponent D (Yonsei University, South Korea).
For majority of the models, the video sequences that are selected from the VQEG database are very short in duration (roughly 10 s only) and hence their ability to portray a real life-streaming scenario is questionable.

In order to increase the precision of in [12] proposed method the extended experiments on greater variety of a video material using the Video Quality Experts Group (VQEG) test sequences are carried out [15].
This metric was submitted to be independently evaluated on MPEG-2 and H.263 video systems by the video quality experts group (VQEG) in their phase II full reference television (FR-TV) test.
From the VQEG Hybrid / Bit-stream Group test plan [20], the DMOS value is calculated using the following formula.
Some other methods pending for standardization are: VQEG and ITU-T Study Group or an independent lab research activities.
The SDTV video programs provided by VQEG [16] which have multiple characteristics of codec effects were selected as the test video sequences.
