ATM network impairment valuation of an experimental 3D videophone for virtual reality telecommunication system

ATM network impairments in terms of CER, CLR, CMR, CDV and CTD are applied to an experimental 3D videophone for audio and 3D video signals quality evaluation study. The effects of the impairments on both signals are evaluated by comparison between unimpaired and impaired sequences. A subjective assessment method together with the IT-R five-grade impairment scale is adopted in performing the evaluation. The results show ATM network impairments effects on both signals can maintain scale 4 of the IT-R five-grade scale. Therefore, good quality of audio and 3D video signals transmission can be confirmed for IT-T ATM performance objectives.
