Abstract
A method of compression by blocks of digital data representing physical quantities comprises a coding configuration step (E3) in which there is associated with each block of digital data a coding technique chosen from amongst a set (E) of acceptable coding techniques as a function of a criterion.The choice criterion is a function of optimization of the rate or distortion characterizing the coding configuration under the constraint of a given computational resource.Use notably in a transmission videophone system.
