Abstract
La presente invención describe la clasificación de contenido estéreo no correlacionado (en lo sucesivo, "clasificación de UNCLR") y la detección de diafonía (en lo sucesivo, "detección de XTALK") en una señal de sonido estéreo de entrada. La presente invención también describe la selección del modo estéreo, por ejemplo, una selección automática del modo estéreo LRTD/DFT. Además, la invención usa dicha clasificación para seleccionar uno de un primer modo estéreo y un segundo modo estéreo para codificar una señal de sonido estéreo que incluya un canal izquierdo y un canal derecho; detectar diafonía en una señal de sonido estéreo que incluya un canal izquierdo y un canal derecho en respuesta a características extraídas de la señal de sonido estéreo que incluya los canales izquierdo y derecho; o clasificar contenido estéreo no correlacionado en una señal de sonido estéreo que incluya un canal izquierdo y un canal derecho en respuesta a características extraídas de la señal de sonido estéreo que incluya los canales izquierdo y derecho.
