Methods and apparatus for encoding and decoding signals, methods for transmitting signals, and an information recording medium |
摘要 |
A method for encoding the information has a forward inverse transform step of forward orthogonal transforming an input signal using a pre-set windowing function to form an output spectral signal, and an encoding step of encoding the resulting output spectral signal from the forward orthogonal transform. The preset windowing function having a smaller slope of a characteristic curve at both skirt ends is employed. This allows efficient encoding when employing a transform constituting a waveform signal by overlapping waveform elements with both neighboring waveform elements for generating a waveform signal during inverse orthogonal transform, such as MDCT.
