N2 - An improved motion estimation method for robust video coding is proposed. It is designed to enhance packet loss resilience in lossy environments. The proposed motion estimation is based on an end-to-end rate-distortion optimisation framework. Initially, the end-to-end reconstructed distortion is efficiently estimated considering the distortion caused by quantisation, error propagation, and error concealment. Then, the total bit rate for coding the residual is estimated using a quadratic rate-distortion model. The results are incorporated into the Lagrangian optimisation during motion estimation. Optimised motion vectors are selected in the sense of coding efficiency and robustness. A comparative evaluation with conventional robust video coding techniques was conducted. The experimental results demonstrate a superior performance of the proposed method.
