Abstract
Se proporciona un método de decodificación de video que incluye: determinar un modo de predicción de un bloque actual para que sea uno de un modo de salto y un modo de combinación; cuando se va a usar un vector de movimiento, que es determinado a partir de una lista de candidatos de combinación del bloque actual, y una diferencia de vector de movimiento de combinación, se obtiene información de candidatos de combinación que indica un candidato en la lista de candidatos de combinación mediante la codificación de entropía sobre un flujo de bits aplicando una pieza de información de contexto; se determina un vector de movimiento base a partir de un candidato determinado a partir de la lista de candidatos de combinación, con base en la información de candidatos de combinación; y se determina un vector de movimiento del bloque actual usando un índice de distancia de una diferencia de vector de movimiento de combinación del bloque actual y un índice de dirección de la diferencia de vector de movimiento de combinación para usar el vector de movimiento base y la diferencia de vector de movimiento de combinación.
