DATA SIGNAL ENCODING

摘要

FIELD: information technology. ^ SUBSTANCE: very crude quantisation which exceeds a measure defined by a masking threshold without or only with very small quality losses is provided by quantisation of not a directly pre-filtered signal, but prediction errors obtained in accordance with adaptive prediction ahead the pre-filtered signal. ^ EFFECT: due to the adaptability applied ahead, the quantisation error does not have negative effect on prediction on the side of the decoder. ^ 49 cl, 10 dwg
