Abstract
When a selective decision of the field mode/frame mode for orthogonal transform is made for each macroblock composed of a plurality of blocks in a motion picture coding system wherein coding of an interlaced TV signal proceeds in the frame structure and an orthogonal transform is made in the unit of a block, the respective variances of the blocks within the macroblock are calculated, the calculated results are substituted respectively into an monotonously increasing and saturation tending nonlinear function to evaluate the sum of these functional values, and such a decision is made as to select the smaller mode in sum.
