This paper studies the quality evaluation of three-dimensional col-our-plus depth videos over error prone IP networks. Scalable and multiple-description coding techniques are utilized for transmis-sion. In order to study the impact of packet losses to the perceived 3D video quality, path diversity is characterized by asymmetric packet losses. Mean Opinion Score (MOS) for the multiple description scheme is affected by both the encoding parameters and the sensed packet loss rate at each 3D description. Moreover, the effect of 3D video reconstruction through interpolation using a single, reliably delivered description has been compared against using all delivered descriptions, and it is found out that subject’s rate the 3D videos reconstructed using a single descriptions higher scores under severe packet loss rate conditions.
