A plug-in hybrid vehicle is driven by one or more electric motors powered by a battery system with supplemental electric power provided by a gasoline engine powered generator. The method comprises the steps of demodulating and decoding an input signal having input data to produce a data output, remodulating the data output to produce a pseudo-training sequence including an idealized input signal, and generating equalizer parameters from the pseudo-training sequence. Next, if the vertical component of the estimated frame motion vector is an odd value, the bottom field pixels in the received macroblock are matched with top field pixels in a reference frame that correspond to motion vectors obtained by scaling the vertical component of the original motion vectors depending on a field-to-field distance.
