Abstract
UNA VIDEOGRABADORA DE DOBLE PLATINA, QUE TIENE PRIMERA Y SEGUNDA PLATINAS DE VIDEO (21, 31) EN UN ALOJAMIENTO COMUN, PUDIENDO AMBAS PLATINAS REPRODUCIR Y, AL MENOS UNA DE ELLAS, GRABAR. SE CONECTA UN CONJUNTO DE CONMUTADOR (22, 32) A AMBAS PLATINAS PARA PERMITIR LAS CONEXIONES SELECTIVAS DE LAS SEÑALES DE AUDIO Y VIDEO ENTRE LAS DOS PLATINAS. EXISTE UN DETECTOR (52) PARA DETECTAR LA POSICION DE LA FASE ANGULAR DE LOS CABEZALES DE CADA PLATINA PARA ASEGURAR QUE ESTAN EN FASE ANTES DE INICIARSE LA GRABACION Y UN CONTROLADOR (6) PARA CORREGIR LA POSICION DE LOS CABEZALES DE, AL MENOS, UNA DE LAS PLATINAS PARA ASEGURAR QUE LOS CABEZALES DE CADA UNA ESTARAN EN LA MISMA FASE ANGULAR. HAY, AL MENOS, DOS TIPOS DE CIRCUITOS DE DUPLICADO Y EL CONJUNTO DE CONMUTACION PERMITE LAS CONEXIONES SELECTIVAS DE LAS SEÑALES DE AUDIO Y VIDEO ENTRE LAS DOS PLATINAS.
