Abstract
The invention concerns a method of coding a set of coefficients representing physical quantities. The method includes the step of selecting, for each coefficient to be coded, a first or second coding mode according to a coding cost, the first coding mode including the calculation of an amplitude model, and the determination of a path (P) amongst the coefficients. The method also includes the steps of coding the length of the path, coding the coefficients for which the first coding mode has been selected, by the first coding mode, and coding the coefficients for which the second coding mode has been selected, by the second coding mode.
