Abstract
In an information processing apparatus, for example, a video tape recorder, a recording section records an input signal on a recording medium. Substantially at the same time, a playback section plays back the input signal from the recording medium to output a playback signal. A learning section generates prediction coefficients based on characteristics of the playback signal and the original input signal. Then, when the playback section plays back the input signal recorded on the recording medium to output the playback signal, a classification-adaptation section corrects the playback signal based on the prediction coefficients generated by the learning section, outputting a corrected playback signal.
