Abstract
Official abstract text for this publication.
A binary allocation in a hierarchical coding/decoding comprising a coding/decoding of a digital signal enhancement layer. The signal comprises a succession of L samples, each sample being represented by a mantissa and an exponent. The method comprises the allocation of a predetermined number N b of enhancement bits to a part at least of the L samples of highest exponent values. In particular, the method comprises the steps: a) enumerating the exponents of the L samples each having a given value, b) calculating at least one aggregate of enumerations of exponents by decreasing values of exponent until the predetermined number N b is approximated from above, for c) determining a threshold value of largest exponent iexp0 of sample for which no more enhancement bit is available, and allocating the N b enhancement bits, according to chosen rules, to the samples whose exponent is greater than the aforesaid threshold value iexp o .
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for bit allocation in a hierarchical coding/decoding comprising coding/decoding of a digital signal enhancement layer comprising a succession of L samples, each sample comprising a mantissa and an exponent, the method comprising the allocation of a predetermined number N b of enhancement bits to at least some of the L samples having the greatest exponent values, wherein the method is implemented by a processor of a coder/decoder and comprises…
