Abstract

Se proporciona un método de decodificación. El método incluye: analizar un flujo de bits para obtener un elemento de sintaxis, en donde el elemento de sintaxis incluye por lo menos un índice de información de movimiento candidata óptima de un bloque actual (s151); determinar, con base en el elemento de sintaxis, que se construya una primera lista o una segunda lista para el bloque actual (s152), en donde la primera lista es una lista de información de movimiento candidata basada en bloque, y la segunda lista es una lista de información de movimiento candidata basada en subbloque; determinar información de movimiento óptima de la primera lista o la segunda lista con base en el índice (s153); y predecir el bloque actual con base en la información de movimiento óptima (s154). En este método, la lista de información de movimiento candidata basada en bloque (BLOCK) y la lista de información de movimiento candidata basada en subbloque (Sub-BLOCK) se distinguen entre sí. Esto reduce de forma efectiva los costos de transmisión de la información de movimiento candidata óptima.
