Abstract
Se proporciona un método para decodificar una corriente de bits por medio de un dispositivo electrónico. Una trama de imagen es recibida de la corriente de bits. Una unidad de bloque se determina a partir de la trama de imagen. Un índice de modo de intra-predicción que corresponde a uno de una pluralidad de modos de candidatos de ángulo ancho cada uno que tiene un parámetro de ángulo se determina para la unidad de bloque con base en la corriente de bits. Una pluralidad de muestras de referencia que colindan con la unidad de bloque se determina. El dispositivo electrónico determina si el índice de modo de intra-predicción es diferente de los índices predefinidos cada uno que corresponde a uno de los modos de ángulo ancho predefinidos en los modos de candidatos de ángulo ancho. Una pluralidad de muestras filtradas es generada por un filtro de interpolación con base en las muestras de referencia cuando el índice de modo de intra-predicción es diferente de los índices predefinidos. La unidad de bloque se reconstruye con base en las muestras filtradas a lo largo de una dirección de modo del índice de modo de intra-predicción.
