SELECTION OF DECODING FUNCTIONS DISTRIBUTED TO THE DECODER

摘要

The invention relates to a method for transmitting at least one current image part, characterised in that: an encoding function is selected (10) from a finished set of encoding functions by applying (14) at least one first type of chosen function, said first type of chosen function(s) using image data which has already been decoded; the current image part is encoded (20) by means of the selected encoding function; the encoded image part is transmitted (30) towards a decoder (6); and information describing the chosen function(s) of the first type is transmitted (34) towards the decoder. The invention also relates to the corresponding decoding method.
