Consider the following 4 x 4 pixel macroblock which displays the output from the Discrete Cosine Transform (DCT) stage of MPEG intra-frame video coding process. 179 110 20 42 8 If a constant (Q-Table) quantisation value of 22 is applied to all DCT coefficients, what will be the resulting DCT macroblock after quantising? You must include your calculations for the 4 values in the top row of the macroblock. If thresholding is now applied to the quantised DCT macroblock, where a threshold value of 1=3 is used, what will be the corresponding macroblock values?
