Abstract

Un dispositivo codificador de video que incluye una sección transcodificadora de datos codificados 131 para transcodificar primeros datos codificados generados por una primera sección codificadora de video 11 para generar segundos datos codificados, en donde la sección transcodificadora de datos codificados 131 incluye: una sección de adición de modo de predicción 1312 para generar modos de intra-predicción inutilizables por la primera sección codificadora de video 11 y utilizables por una segunda sección codificadora de video 14; y una sección de selección de modo de predicción 1313 para evaluar los modos de predicción generados por la sección de adición de modo de predicción 1312 y, sobre la base de los resultados de la evaluación, seleccionar un modo de predicción usado por la segunda sección codificadora de video 14.
