Abstract
Se presenta un metodo y sistema para codificar y decodificar contenido de video digital. El contenido de video digital comprende una corriente de imagenes que pueden ser, cada una, intra-imagenes, imagenes pronosticadas o imagenes bi-pronosticadas. Cada una de las imagenes comprende macrobloques que, a cu vez, pueden ser divididos en bloques mas pequenos. El metodo incluye la codificacion y decodificacion de cada imagen en dicha corriente de imagenes ya sea en modo de cuadro o en modo de campo.
