Abstract

UN APARATO DE REGISTRO Y REPRODUCCION DIGITAL QUE REGISTRA DOS TIPOS DE SEÑALES DIGITALES DE UN PROGRAMA DE VIDEO IDENTICO, GENERADAS MEDIANTE UNA CODIFICACION MUY EFICIENTE, O UNA SEÑAL DE VELOCIDAD DE TRANSFERENCIA DE BITS RELATIVAMENTE ALTA Y UNA SEÑAL DE VELOCIDAD DE TRANSFERENCIA DE BITS RELATIVAMENTE BAJA, EN APROXIMADAMENTE LAS MISMAS POSICIONES DE LA CINTA. CUANDO LA SEÑAL DE BAJA VELOCIDAD DE TRANSFERENCIA DE BITS SE UTILIZA NORMALMENTE PARA UNA REPRODUCCION Y UNA BUSQUEDA-REPRODUCCION NORMALES O CUANDO SOLO SE UTILIZA PARA LA BUSQUEDA-REPRODUCCION, LA CANTIDAD DE DATOS DE BUSQUEDA-REPRODUCCION SE AJUSTA COMO SI LOS DATOS DE UNA SERIE DE CUADROS FUERAN UNA UNIDAD PARA UN TRABAJO DE EDICION QUE SE PUEDE REGISTRAR EN UN NUMERO ENTERO DE PISTAS.
