Abstract

Un proceso para seleccionar un conjunto de transformación para un bloque de predicción. El proceso puede usarse tanto en un codificador como en un decodificador. Por ejemplo, el proceso puede usarse tanto en un codificador como en un decodificador para un bloque de predicción que se haya predicho a partir de un bloque de referencia. En algunas modalidades, tanto el bloque de predicción como el bloque de referencia son bloques intra.
