Claim:
1. A method of processing video data, the method comprising: generating a prediction signal (PS) corresponding to a Macro Block (MB); calculating a prediction residue signal (PRS) of the MB from the prediction signal (PS); predicting a reconstructed prediction residual signal (RPRS) from a reconstructed residue reference frame (RRRF); identifying an error of residue signal (EORS) by subtracting the RPRS from the PRS; comparing the PRS of the MB and the EORS; identifying a residue signal having a least error value based on a result of the comparison; and generating an encoded bit stream for transmission based on the residue signal having the least error value, wherein the residue signal is identified by correlating the prediction residue signal of the MB and the reconstructed prediction residue signal (RPRS) of a reference frame.
