Claim One:
1. A method for measuring quality of experience (QoE) of a mobile video service, the method comprising: pre-processing, with a processor coupled to a memory storing instructions, a peak signal-to-noise ratio (PSNR) of each segment of a sample video at each bit rate to obtain a differential PSNR (dPSNR) of each segment of the sample video at each bit rate, wherein the dPSNR of each segment is a difference between a PSNR of the segment at the bit rate and a PSNR of the segment corresponding to a maximum bit rate in the same sample video; determining, with the processor for the dPSNR of each segment, a preset parameter of a received video that is obtained according to the sample video, wherein the preset parameter comprises a mean dPSNR, a maximum (max) dPSNR, a minimum (min) dPSNR, and a variance (std) dPSNR; determining, with the processor, an enhanced PSNR (ePSNR) predictive model according to corresponding mean opinion scores (MOSs) and by linear fitting on the preset parameters, wherein ePSNR=a×mean dPSNR+b×max dPSNR+c×min dPSNR+d×std dPSNR, and wherein a, b, c, and d are parameters that enable correlation between the ePSNR and the MOS to be the largest; and determining, with the processor, an enhanced MOS (eMOS) predictive model by linear fitting on the determined ePSNR and the corresponding MOS, wherein eMOS=e×ePSNR+f, wherein each of a, b, c, d, e are non-zero at a same instant, and wherein each of a, b, c, d, e are finite.
