Abstract
The method is characterized in that the step for selecting a coding mode from the inter modes and from the intra modes is broken down into two sequential steps, a step for preselecting the intra coding mode for preselecting an intra mode for the current macroblock from the intra coding modes, and a coding decision step, part of the effective coding of the current macroblock for selecting the mode of coding the current macroblock from the inter modes and the preselected intra mode and in that the preselection step for the current macroblock is carried out during the coding decision step for a preceding macroblock.
