When highly redundant information that expresses five tones using 4 bits is transferred to a printer in terms of a unit data length in data transfer, efficiency is very poor. First spectral coefficients for the first and the second frame are derived using the first warp information and a first weighted representation of the first and the second frame, the first weighted representation derived by applying a first window function to the first and the second frames, wherein the first window function depends on the first warp information. The schedule is printed on paper divided into sections by lines of perforation.
