Abstract (en)
[origin: US2006036435A1] A maximum of Nmax bits for encoding is defined for a set of parameters which may be calculated from a signal frame. The parameters for a first sub-set are calculated and encoded with N0 bits, where N0<Nmax. The allocation of Nmax-N0 encoding bits for the parameters of a second sub-set are determined and the encoding bits allocated to the parameters for the second sub-set are classified. The allocation and/or order of classification of the encoding bits are determined as a function of the encoding parameters for the first sub-set. For a total of N available bits for the encoding of the total parameters (N0<N=Nmax), the parameters for the second sub-set allocated the N-N0 encoding bits classified the first in said order are selected. Said selected parameters are calculated and encoded to give the N-N0 bits. The N0 encoding bits for the first sub-set and the N-N0 encoding bits for the selected parameters for the second sub-set are finally introduced into the output sequence of the encoder.
