Abstract
Un método de ejemplo de decodificación de datos de video que incluye recibir uno o más elementos de sintaxis de los datos de video indicativos de si se aplica un primer tipo de esquema de codificación o un segundo tipo de esquema de codificación a los valores residuales de un bloque de datos de video codificados con salto de transformada, donde los valores residuales son indicativos de una diferencia entre el bloque y un bloque de predicción, y donde, en el salto de transformada, los valores residuales no se transforman de un dominio de muestra a un dominio de frecuencia. El método incluye determinar un tipo de esquema de codificación para aplicar a los valores residuales con base en el uno o más elementos de sintaxis, determinar los valores residuales con base en el tipo determinado de esquema de codificación y reconstruir el bloque con base en los valores residuales determinados y el bloque de predicción.
