THIS INVENTION RELATES TO A METHOD, A DEVICE AND A SOFTWARE APPLICATION PRODUCT FOR N-LEVEL QUANTIZATION OF VECTORS, WHEREIN N IS SELECTABLE PRIOR TO SAID QUANTIZATION FROM A SET OF AT LEAST TWO PRE-DEFINED VALUES THAT ARE SMALLER THAN OR EQUAL TO A PRE-DEFINED MAXIMUM NUMBER OF LEVELS M. A REPRODUCTION VECTOR FOR EACH VECTOR IS SELECTED FROM AN N-LEVEL CODEBOOK OF N REPRODUCTION VECTORS THAT ARE, FOR EACH N IN SAID SET OF AT LEAST TWO PRE-DEFINED VALUES, REPRESENTED BY THE FIRST N REPRODUCTION VECTORS OF THE SAME JOINT CODEBOOK OF M REPRODUCTION VECTORS. THE INVENTION FURTHER RELATES TO A METHOD, A DEVICE AND A SOFTWARE APPLICATION PRODUCT FOR RETRIEVING REPRODUCTION VECTORS FOR VECTORS THAT HAVE BEEN N-LEVEL QUANTIZED, TO A SYSTEM FOR TRANSFERRING REPRESENTATIONS OF VECTORS, TO A METHOD, A DEVICE AND A SOFTWARE APPLICATION PRODUCT FOR DETERMINING A JOINT CODEBOOK, AND TO SUCH A JOINT CODEBOOK ITSELF.
