Abstract

DISPOSITIVO DE GRABACION Y REPRODUCCION DE UNA SEÑAL DE VIDEO, POR EJEMPLO UN GRABADOR DE CINTAS DE VIDEO, ADAPTADA A UN CANAL SELECCIONADO PARA SER UNO DE LOS MUCHOS CANALES DE UHF DE TELEVISION. UN MICROCONTROLADOR DEL DISPOSITIVO ACTIVA UN SELECTOR DE UHF PARA CADA CANAL UHF POR TURNO Y CHEQUEA EL NIVEL DE LA SEÑAL DEL CANAL. SE SELECCIONA UN CANAL LIBRE QUE NO CONTIENE SEÑALES, SOLO CUANDO EL CANAL INMEDIATAMENTE INFERIOR NO CONTIENE UNA TRANSMISION DE TELEVISION BUSCADA. UNA VEZ HECHA LA SELECCION, EL MICROCONTROLADOR LLEVA LA FRECUENCIA DEL CANAL DE REPRODUCCION A LA DEL CANAL SELECCIONADO.
