Abstract
Un codificador (100) incluye: circuitería; y una memoria acoplada a la circuitería. La circuitería, en operación, almacena un primer parámetro en una corriente de bits, el primer parámetro indica, como un modo de predicción, uno de (i) un modo de predicción múltiple en el cual se genera una imagen de predicción al superponer una imagen de inter-predicción de un bloque actual y una imagen de intra-predicción del bloque actual y (ii) uno de una pluralidad de modos de predicción que incluyen un modo no rectangular en el cual se genera una imagen de predicción para cada partición no rectangular en el bloque actual, y codifica el bloque actual de acuerdo con el modo de predicción.
