This paper analyzes how transmission errors in the texture and depth map jointly affect the synthesized virtual view in 3-D video coding. In particular, we propose a framework that decouples the effects attributed to transmission errors in texture and depth to facilitate theoretical analysis. The synthesis distortion due to depth map errors is characterized in the frequency domain using a new approach that combines the energy density of the reconstructed texture and channel errors. Experimental results show that our analytical model can accurately estimate the rendering view quality.
