Abstract

Un método para codificar valores del parámetro de cuantificación delta. En un ejemplo, un decodificador de video puede recibir un valor de parámetro de cuantificación D (dQP) para un bloque de cuantificación actual de datos de video, donde el valor de dQP se recibe existan o no coeficientes de transformada distintos de cero en el bloque de cuantificación actual. En otro ejemplo, un decodificador de video puede recibir el valor de dQP para el bloque de cuantificación actual de datos de video solo en el caso que el predictor de QP para el bloque de cuantificación actual tiene un valor de cero, e inferir que el valor de dQP es cero en el caso de que el pronosticador de QP para el bloque de cuantificación actual tiene un valor distinto de cero, y no existen coeficientes de transformada distintos de cero en el bloque de cuantificación actual.
