DATA ENCODING APPARATUS, DATA ENCODING METHOD, DATA OUTPUT APPARATUS, DATA OUTPUT METHOD, SIGNAL PROCESSING SYSTEM, SIGNAL PROCESSING APPARATUS, SIGNAL PROCESSING METHOD, DATA DECODING APPARATUS, AND DATA DECODING METHOD

An apparatus for encoding data includes a receiving section, a signal-deteriorating factor generation section, and a data-encoding section. The signal-deteriorating generating section generates a signal-deteriorating factor and includes a phase-shifting section to shift a phase of data received at the receiving section. The data-encoding section obtains encoded data by performing encoding processing on the data in which the signal-deteriorating factor is generated and includes an encoding section to perform encoding by use of sub-sampling on the data whose phase is shifted by the phase-shifting section.
