Abstract

LA INVENCION SE REFIERE GENERALMENTE A CANALES MULTIPLES PARA TRANSMITIR Y PARA RECIBIR INFORMACION, PARTICULARMENTE INFORMACION DE AUDIO QUE REPRESENTA UN CAMPO DE SONIDO MULTIDIRECCIONAL. MAS PARTICULARMENTE, LA INVENCION SE REFIERE A DISPOSITIVOS Y METODOS QUE SUMINISTRAN SEÑALES QUE SON COMPATIBLES CON RECEPTORES MULTICANAL Y CON DESCODIFICADORES DE MATRIZ TALES COMO LA MATRIZ MP UTILIZADA PARA LA BANDA DE SONIDO DE MUCHAS PELICULAS. EN UN TRANSMISOR MULTICANAL, UNA RED PREPARA LAS SEÑALES INTERMEDIAS QUE SE CODIFICAN MEDIANTE PROCESADORES DE ANALISIS DE SEÑAL EN UNA SEÑAL PARA SU TRANSMISION O ALMACENAMIENTO SUBSECUENTE. EN UN RECEPTOR MULTICANAL, LA INFORMACION EXTRAIDA DE LA SEÑAL CODIFICADA RECIBIDA SE COMBINA EN UNA RED Y SE PROCESA MEDIANTE PROCESADORES DE SINTESIS DE SEÑAL PARA SUMINISTRAR SEÑALES DE SALIDA QUE SEAN COMPATIBLES CON UN DESCODIFICADOR DE MATRIZ.
