Abstract
A data processing apparatus includes an input terminal for receiving an audio signal, a 1-bit A/D converter for A/D converting the audio signal into a 1-bit bitstream signal, and a prediction unit for carrying out a prediction step on the bitstream signal so as to obtain a predicted bitstream signal. The data processing apparatus further includes a signal combination unit for combining the bitstream signal and the predicted bitstream signal so as to obtain a residue bitstream signal. A recording apparatus or a transmitter apparatus can use the data processing apparatus. The residue bitstream signal is data compressed by lossless encoding and then error encoded and channel encoded prior to transmission through a media.
