Abstract
A method for decoding a coded data stream representative of at least one image, the image being divided into blocks, a set of at least two prediction modes being available for predicting a current block. The method includes: obtaining at least two categories of prediction modes from the set; eliminating at least one category in accordance with at least one first predetermined elimination criterion; updating the categories not eliminated by deleting prediction modes that are common with the at least one eliminated category; and decoding, from the data stream, an information identifying for the current block a prediction mode among the modes of the updated categories.
