Abstract:
A signal processing system for a code string of a predetermined format obtained by coding a signal, the system comprising:first code string generation means for generating a first code string by replacing a part of the code string of the predetermined format with dummy data; second code string generation means for generating a second code string for complementing the dummy data part of the first code string; first code string provision means for providing the first code string; second code string provision means for providing the second code string; rewriting means for rewriting the dummy data of the first code string received from the first code string provision means to the second code string received from the second code string provision means; and switching means for switching and outputting the first code string and the code string from the rewriting means in accordance with a predetermined condition; wherein the code string of the predetermined format comprises normalization factor information of the signal; and the dummy data comprises dummy data corresponding to at least a part of the normalization factor information.
