Abstract
Disclosed is an encoding device, which is an encoding device that outputs an encoded signal including a signal in which an original signal is encoded, the original signal indicative of at least one of image and audio, which encoding device includes a frequency component extraction section that extracts a part of frequency components of the original signal from the original signal to generate a frequency component extraction signal and an encoding process section that encodes the frequency component extraction signal and the original signal while switching between the frequency component extraction signal and the original signal, and making the signal thus encoded be included in the encoded signal.
