Abstract

Para CD Super Audio (SACD) las senales DSD son codificadas sin perdida, usando enmarcado, prediccion y codificacion de entropía. Además de las senalescodificadas eficientemente, un gran numero de parámetros, esto es la informacion secundaria, debese r almacenada también en el SACD. Cuando menor sea lacapacidad de almacenamiento requerida para la informacion secundaria, mayor será la ganancia total de la codificacion. Por lo tanto se aplican técnicas decodificacion también a la informacionsecund aria para así comprimir la cantidad de datos de la informacion secundaria
