Abstract
Un decodificador de video obtiene una bandera de transposición del flujo de bits. El decodificador de video determina un vector de entrada con base en muestras vecinas para un bloque actual de los datos de video. La bandera de transposición indica si se transpone el vector de entrada. Además, el decodificador de video determina una señal de predicción. La determinación de la señal de predicción incluye multiplicar una matriz MIP por el vector de entrada. La señal de predicción incluye valores correspondientes a un primer conjunto de ubicaciones en un bloque de predicción para el bloque actual y la matriz MIP corresponde al índice de modo MIP. El decodificador de video aplica un proceso de interpolación a la señal de predicción para determinar los valores correspondientes a un segundo conjunto de ubicaciones en el bloque de predicción para el bloque actual.
