Abstract
METODO Y APARATO PARA LA CODIFICACION MULTIPLEXADA DE INFORMACION DIGITAL DE AUDIO EN UN MEDIO DE ALMACENAMIENTO QUE COMPRENDE UNOS CANALES DIGITALES DE AUDIO DE CALIDAD EXTRA-ALTA O ULTRALARGA CON UNA VELOCIDAD TOTAL DE BITS DE DATOS QUE EXCEDE LA VELOCIDAD DE BITS DE DATOS MAXIMA PARA UN MEDIO DE ALMACENAMIENTO DIGITAL, SE GRABAN EN EL MEDIO DE AUDIO. LA GRABACION SE LOGRA COMPRIMIENDO LAS TASAS DE BITS DE DATOS DE LAS SEÑALES DE ENTRADA DE MULTIPLES CANALES DE TAL FORMA QUE SU VELOCIDAD TOTAL DE BITS DE DATOS DESPUES DE LA COMPRESION NO EXCEDE EL MAXIMO PARA EL MEDIO DE ALMACENAMIENTO, MULTIPLEXANDO LAS SEÑALES DE AUDIO COMPRIMIDAS, CODIFICANDO LA SEÑAL MULTIPLEXADA EN UN FORMATO PREDETERMINADO, Y GRABANDO LA SEÑAL CODIFICADA EN EL MEDIO DE ALMACENAMIENTO. UN APARATO PARA GRABAR SEÑALES DE AUDIO DIGITALES CON UNA TASA DE BITS DE DATOS PREDETERMINADA EN UN MEDIO DE ALMACENAMIENTO DIGITAL PERMANENTE.
