摘要 |
A coding method according to the present invention comprises: transforming an input signal (S110a); scanning and quantizing coefficient values which compose the transformed output signal (S120); and entropy coding the quantized coefficients (S130), wherein the transforming (S110a) includes: generating a first transformed output signal by performing a first transform on the input signal using a first transform coefficient (S112); 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 the generated second transformed output signal and a second partial signal that is the remaining part of the first transformed output signal other than the first partial signal (S116a), and a signal corresponding to the second transformed output signal and a signal corresponding to the second partial signal are processed differently in at least one of the scanning, the quantizing, and the entropy coding. |
