Abstract
A movement estimation method and system are disclosed for high definition digital television frames. The movement is estimated for a current block Bc of the even fields T.sub.2k, 2r-1 of the uneven frames with which n movement vectors are associated, with the current block Bc of the even fields T.sub.2k, 2r of the even frames there is associated, by relative addressing, a movement vector with respect to s vectors of the preceding frame I.sub.2r-1 surrounding the frame B'c of the current block Bc. The s vectors are chosen by eliminating the vector redundancies among the n vectors. The invention is applicable to broadcasting and transmission of digital television signals by HD-MAC or HD-MAC NB narrow band channel.
