Claim:
1. A method comprising: processing at least one motion information item pertaining to a current image of a sequence of images, wherein said method comprises: a step of building, with a processing device, at least a list comprising motion information items, including at least one motion previously-selected motion information item, coming from a prediction by motion compensation on the basis of at least one reference image and having been preliminarily encoded, and at least one non-previously-selected motion information item, not preliminarily encoded; a first step of associating, with the processing device, at least one previously-selected motion information item of said list with a motion information item of said list, called a motion information item to be encoded, said first step of associating being implemented according to a first rule of optimization of the cost of encoding said motion information item to be encoded and delivering a modified list comprising at least one association; and a second step of associating, with the processing device, each non-previously-selected motion information item of said list not associated during said first step of associating, with a motion information item to be encoded identified among said non-previously-selected motion information items not associated during said first step of associating and said previously-selected motion information items associated during said first step of associating, said second step of associating being implemented according to a second rule aimed at ensuring that each of the motion information items of said list is associated, during said first or said second steps of association, with a single motion information item to be encoded, said second step of associating delivering a modified list comprising as many associations as there are motion information items in the list built during said building step; encoding at least one current block of said current image of said sequence of images, comprising: selecting a motion information item for said current block from among said motion information items of said modified list; and encoding a motion information item to be encoded associated, during said first or said second step of associating, with said motion information item selected during said step of selecting, delivering a motion information item encoded for said block; and generating a signal representing said at least one encoded block of said current image of said sequence of images, wherein said signal carries said encoded at least one motion information item.
