摘要： In order to determine a quantiser step size for quantising a signal comprising audio or video information, a first quantiser step size and an interference threshold are supplied (502). According to the invention, the actual interference introduced by means of the first quantizer step size is determined (504) and compared with the interference threshold (506). Even if the comparison indicates that the actually introduced interference is higher than the threshold, a second coarser quantizer step size is used (508), that is then used for the quantisation (514) if it emerges that the interference introduced by the coarser second quantizer step size is lower than the threshold or the interference introduced by the first quantiser step size (512). In this way, the quantisation interference is reduced during the coarsening of the quantisation and thus during an increase in the compression gain.
