Abstract

La presente invención se refiere a un método de intra-predicción, y a un codificador y decodificador que lo utilizan. El método de intra-predicción de acuerdo con una modalidad de la presente invención consiste en los pasos de: derivar un modo de predicción de un bloque actual, y generar un bloque de predicción con respecto al bloque actual con base en el modo de predicción del bloque actual. Cuando el modo de predicción del bloque actual es un modo de predicción intra-angular, los valores de las muestras limítrofes de entre las muestras limítrofes izquierdas y las muestras limítrofes superiores del bloque de predicción, las cuales no. Están posicionadas en: una dirección de predicción del modo de predicción. intra-angular, se derivan con base en las muestras de referencia posicionadas en la dirección de predicción del modo de predicción intra-angular y don base en las muestras de referencia adyacentes.
