    • A method of motion prediction of multimedia video coding includes the steps of a) defining that each of macroblocks of enhancement layers has corresponding BL_Residual, EL_Residual, and EL_ResidualME; b) acquiring the BL_Residual that the current macroblock corresponds to from one of the enhancement layers; c) identifying whether the BL_Residual is zero; if it is zero, apply the motion prediction of video coding to the current layer and then proceed to the step e); if it is not zero, proceed to the next step d); d) comparing the BL_Residual that the current macroblock corresponds to with a threshold; if the BL_Residual is smaller than the threshold, apply the motion prediction of video coding to the current layer; if the BL_Residual is bigger than the threshold, proceed to cross-layer-mode motion prediction of video coding; and e) ending.

    • The present invention provides a device and method for applying 1-D and 2-D DCT and IDCT transforms to sets of input data, typically 8×8 or 16×16 matricies of coefficients. In one embodiment, the present invention provides input lines, logic to pre-add input values and generate operands and one or more adder networks that effectively carry out the multiplication operations required to apply a DCT/IDCT transform. The device may apply a 1-D transform twice to accomplish a 2-D transform. Alternatively, the present invention may either include successive stages of logic for the second 1-D transform or it may send data transformed once back through the same logic to pre-add and adder networks for the second 1-D transform. Calculations may be carried out after Booth encoding of operands. The processing may be split between producing vp, a vector of sums of output values, and producing vn, a vector of differences of output values, which vectors may be recombined to produce an output vector v.
