Abstract
De acuerdo con la presente invención, la información de mapeo de movimiento de intercapa puede utilizarse para permitir la predicción de vector de movimiento temporal (TMVP - temporal motion vector prediction) de una capa de mejora de un flujo de bits. Por ejemplo, una imagen de referencia y un vector de movimiento (MV - motion vector) de un bloque de video de intercapa pueden determinarse. La imagen de referencia puede determinarse con base en un bloque de video de capa base intercalado. Por ejemplo, la imagen de referencia puede ser una imagen de referencia de intercapa intercalada de la imagen de referencia del bloque de video de capa base intercalado. El MV puede determinarse con base en un MV del bloque de video de capa base intercalado. Por ejemplo, el MV puede determinarse al determinar el MV del bloque de video de capa base intercalado y escalar el MV del bloque de video de capa base intercalado de acuerdo con una relación espacial entre la capa base y la capa de mejora. La TMVP puede realizarse en la imagen de la capa de mejora utilizando el MV del bloque de video de intercapa.
