Abstract

Un codificador de audio o video y un decodificador de audio o video se basan en una combinación de dos canales de audio o video (201, 202) a fin de obtener una primera señal de combinación (204) como una señal media y una señal residual (205) que puede derivarse mediante el uso de una señal lateral predicha derivada de la señal media. La primera señal de combinación y la señal residual de predicción se codifican (209) y escriben (212) en un flujo de datos (213) junto con la información de predicción (206) derivada mediante un optimizador (207) en base a un objetivo de optimización (208) y un indicador de dirección de predicción que indica una dirección de predicción asociada con la señal residual. Un decodificador utiliza la señal residual de predicción, la primera señal de combinación, el indicador de dirección de predicción y la información de predicción para derivar una primera señal de canal decodificada y una segunda señal de canal decodificada. En un ejemplo de codificador o en un ejemplo de decodificador, se puede aplicar una transformada real a imaginaria para estimar la parte imaginaria del espectro de la primera señal de combinación. Para calcular la señal de predicción utilizada en la derivación de la señal residual de predicción, la primera señal de combinación con valor real se multiplica por una porción real de la información de predicción compleja y la parte imaginaria estimada de la primera señal de combinación se multiplica por una porción imaginaria de la información de predicción compleja.
