ABSTRACT:
A coding device comprises a coding circuit in which a range of values, which local decoded values are permitted to have is made narrower than a range of values, which input sample values are permitted to have when coding a differential value between an input sample value and its predictive value. A decoding device substitutes a decoded value to be subsequently decoded for a decoded value in which a gradient overload is produced when decoding a code provided by coding a differential value between an input sample value and its predictive value.
