Abstract

UN APARATO DE GRABACION Y REPRODUCCION DIGITAL GRABA SIMULTANEAMENTE DOS CLASES DE SEÑALES DIGITALES DE UN PROGRAMA DE VIDEO IDENTICO, GENERADAS POR CODIFICACION DE ALTA EFICIENCIA, O UNA SEÑAL CON UNA VELOCIDAD DE BITS RELATIVAMENTE ALTA Y UNA SEÑAL CON UNA VELOCIDAD DE BITS RELATIVAMENTE BAJA, SOBRE APROXIMADAMENTE LA MISMA POSICION SOBRE LA CINTA. EL APARATO ESTA CONSTRUIDO DE MANERA QUE LA SEÑAL DE BAJA VELOCIDAD DE BITS SE USA COMUNMENTE PARA LA REPRODUCCION NORMAL Y LA BUSQUEDAREPRODUCCION. ADEMAS, EL TIEMPO DE GRABACION PUEDE PROLONGARSE REDUCIENDO LA VELOCIDAD DE BITS DE LA GRABACION.
