Abstract

Se proporcionan métodos y aparatos para determinar predictores de parámetro de cuantificación a partir de una pluralidad de parámetros de cuantificación contiguos. Un aparato incluye un codificador (300) para codificar datos de imagen para al amenos una porción de una imagen utilizando un predictor de parámetro de cuantificación para un parámetro de cuantificación actual que será aplicado a los datos de imagen. El predictor de parámetro de cuantificación se determina utilizando múltiples parámetros de cuantificación a partir de porciones contiguas previamente codificadas. Una diferencia entre el parámetro de cuantificación actual y el predictor de parámetro de cuantificación se codifica para dar señal a un descodificador correspondiente.
