【摘要】：目前,對(duì)視頻業(yè)務(wù)體驗(yàn)質(zhì)量(QoE)的客觀(guān)評(píng)估方法中,視頻圖像質(zhì)量下降造成的可見(jiàn)顯示損傷持續(xù)時(shí)間對(duì)用戶(hù)體驗(yàn)質(zhì)量的影響往往被忽略。針對(duì)該問(wèn)題,討論了可見(jiàn)顯示損傷持續(xù)時(shí)間對(duì)用戶(hù)體驗(yàn)質(zhì)量的影響。同時(shí),分析了造成可見(jiàn)顯示持續(xù)損傷的客觀(guān)原因,構(gòu)建了包含分層客觀(guān)指標(biāo)和主觀(guān)評(píng)估結(jié)果的貝葉斯網(wǎng)絡(luò)。在此基礎(chǔ)上,提出了針對(duì)視頻業(yè)務(wù)體驗(yàn)質(zhì)量的無(wú)參考評(píng)估方法,并通過(guò)主觀(guān)測(cè)試驗(yàn)證了該方法的準(zhǔn)確性。
[Abstract]:At present, in the objective evaluation method of video service experience quality (QoS), the effect of visual display damage duration caused by video image quality degradation on user experience quality is often ignored.Aiming at this problem, the effect of visible display injury duration on user experience quality is discussed.At the same time, the objective causes of visible and continuous damage are analyzed, and a Bayesian network is constructed, which includes hierarchical objective indexes and subjective evaluation results.On this basis, a non-reference evaluation method for video service experience quality is proposed, and the accuracy of the method is verified by subjective test.
