ABSTRACT:
The present invention relates to a method of encoding a sequence of pictures, a picture being divided into blocks of data, said encoding method comprising the steps of:—computing a residual error block from a difference between a current block contained in a current picture and a candidate area using of a prediction function,—computing an entropy of the residual error block,—computing an overall error between said current block and said candidate area,—estimating a power consumption of a video processing device adapted to implement said prediction function,—computing a rate-distortion value on the basis of the entropy, the overall error and the estimated power consumption of the video processing device,—applying the preceding steps to a set of candidate areas using a set of prediction functions in order to select a prediction function according to the rate-distortion value.
