CA 2706711

A method and apparatus for selecting a coding mode are described. For example, the method receives at least one block of a signal to be encoded. The method determines a frame vertical pixel difference in the at least one block and determines a field vertical pixel difference in the at least one block. The method then compares the frame vertical pixel difference with the field vertical pixel difference to determine a first coding mode for the at least one block.

L'invention concerne un procédé et un appareil pour sélectionner un mode de codage. Par exemple, le procédé reçoit au moins un bloc d'un signal à encoder. Le procédé détermine une différence de pixel vertical de trame dans le bloc et détermine une différence de pixel vertical de champ dans le bloc. Le procédé compare ensuite la différence de pixel vertical de trame avec la différence de pixels verticale de champ pour déterminer un premier mode de codage pour le bloc.
