Abstract

Un decodificador de video puede determinar, con base en elementos de sintaxis en una corriente de bits que comprende una representación codificada de los datos de video, muestras cuantificadas residuales de un bloque de los datos de video. Adicionalmente, el decodificador de video puede determinar valores residuales cuantificados con base en las muestras cuantificadas residuales. Después de determinar los valores residuales cuantificados, el decodificador de video puede cuantificar a la inversa los valores residuales cuantificados. El decodificador de video puede generar valores predichos ejecutando intra predicción para el bloque utilizando muestras no filtradas de las muestras de límite de bloque de encima o izquierda. Además, el decodificador de video puede reconstruir valores muestra originales del bloque con base en los valores residuales cuantificados a la inversa y los valores de predicció
