Abstract
EN UN APARATO REPRODUCTOR DE VIDEO, UN CIRCUITO DE INSERCION DE INFORMACION DE PLEGAMIENTO DE FRECUENCIA COMPRENDE UN DETECTOR DE CAMPO E/O 30 PARA DETECTAR SI LA SEÑAL DE VIDEO PRESENTE ES DE UN CAMPO DE NUMERO PAR O NUMERO IMPAR, UN GENERADOR DE INFORMACION DE PLEGAMIENTO DE FRECUENCIA 40 PARA GENERAR INFORMACION DE PLEGAMIENTO DE FRECUENCIA DF QUE REPRESENTA EL ESTADO DE PLEGAMIENTO DE FRECUENCIA DE ACUERDO AL RESULTADO DETECTADO DEL DETECTOR DE CAMPO E/O 30, UN SUMADOR 60 PARA SUMAR UNA SEÑAL DE VIDEO PLEGADA FL A LA INFORMACION DE PLEGAMIENTO DE FRECUENCIA DF, Y UN FIJADOR DE POSICION 50 CONECTADO ENTRE EL SUMADOR 60 Y EL GENERADOR DE INFORMACION DE PLEGAMIENTO DE FRECUENCIA 40 PARA SUMINISTRAR LA INFORMACION DE PLEGAMIENTO DE FRECUENCIA GENERADA AL SUMADOR 60 EN CUALQUIER MOMENTO ARBITRARIO. EN UN APARATO REPRODUCTOR DE VIDEO, UN CIRCUITO DE SEPARACION DE INFORMACION DE PLEGAMIENTO DE FRECUENCIA COMPRENDE UN DETECTOR DE POSICION 120 PARA DETECTAR LA POSICION DONDE LA INFORMACION DE PLEGAMIENTO DE FRECUENCIA ES INSERTADA EN LA SEÑAL DE VIDEO REPRODUCIDA, Y UN SEPARADOR DE INFORMACION DE PLEGAMIENTO DE FRECUENCIA 130 PARA SEPARAR LA INFORMACION DE PLEGAMIENTO DE FRECUENCIA INCLUIDA EN LA SEÑAL DE VIDEO REPRODUCIDA DE ACUERDO AL RESULTADO DETECTADO DEL DETECTOR DE POSICION 120.
