摘要 |
A coding method according to the present invention comprises: transforming an input signal to generate a transformed output signal; quantizing the transformed output signal to generate quantized coefficients; and entropy coding the quantized coefficients to generate a coded signal, wherein the transforming includes: generating a first transformed output signal by performing a first transform on the input signal using a first transform coefficient; and generating a second transformed output signal by performing, using a second transform coefficient, a second transform on a first partial signal which is a part of the first transformed output signal, and outputting the transformed output signal including (i) the generated second transformed output signal and (ii) a second partial signal which is the remaining part of the first transformed output signal other than the first partial signal.
