Abstract

The method is characterized in that the pre-analysis phase performs correlation level calculations of the even and odd field blocks of the current picture with the even and odd blocks of the current picture with the even and odd field blocks of the reference picture based on motion vectors calculated during this phase and corresponding to the blocks to impose, during the coding mode decision stage and among the inter coding modes, the inter coding between fields of the same parity or of opposing parity or the inter coding between frames, according to the correlation levels.
