Abstract
A method of transcoding a digital signal encoded according to a first encoding mode into a digital signal encoded according to a second encoding mode, the second encoding mode comprising a bit rate-distortion allocation of the encoded digital signal. The method comprises the steps of obtaining at least a first parameter of encoding the signal according to the first mode, obtaining at least a second parameter from an at least partial encoding of the signal according to the second mode, and selecting a bit rate-distortion allocation mode for the encoding of the signal according to the second mode, as a function of the first and second parameters.
