PROBLEM TO BE SOLVED: To convert a non-sound code (CN code) encoded by an encoding method on the transmission side to a non-sound code conforming to an encoding method on the reception side without decoding to a CN signal. SOLUTION: A first non-sound code obtained by encoding a non-sound signal included in an input signal by the non-sound compressing function of a first sound encoding system is converted to a second non-sound code of a second sound encoding system without being temporarily decoded to a non-sound signal. For example, the first non-sound code is separated into a plurality of first element codes by a code separation part 61, and the first element codes are converted to a plurality of second element codes constituting the second non- sound code by CN code conversion parts 621 to 62n , and the second element codes obtained by this conversion are multiplexed to output the second non- sound code. |
