Abstract :
This paper analyzes transmission-error induced distortion in decoded video. A recursion model is derived that relates the distortion in successive P-frames. The model takes into account of non-integer motion vectors used for motion-compensated temporal prediction and concealment, unconstrained intra prediction, and in-loop deblocking filtering. Experimental data show that the model is quite accurate over a large range of packet loss rates and encoder intra rates.
