A reduced-complexity but effective search scheme for rate-distortion (RD) optimisation of motion vector and displaced-frame-difference coding is proposed. Through predicting the relative order of the RD-Lagrange rests, a large proportion of suboptimal displacement Vector positions are eliminated. In comparison with a popular H.263 test model, the proposed scheme leads to a similar to 0.5dB improvement in the peak signal-to-noise ratio.
