Abstract:
1. A transmission system comprising: a decoding device as a receiving device, the decoding device outputs an output signal by receiving, as an input, an encoded signal including a signal in which an original signal is encoded, the original signal being indicative of contents of at least one of image and audio, and the output signal being indicative of the contents, the decoding device including, an encoding device as a sending device, the encoding device including (i) a frequency component extracting filter configured to extract, from the original signal, a part of frequency components included in the original signal, to generate a frequency component extraction signal and (ii) an encoder configured to (a) encode the frequency component extraction signal and the original signal in such a manner that the encoding is carried out while switching over between the frequency component extraction signal and the original signal, and (b) make the signal thus encoded be included in the encoded signal.
