Abstract

UN CIRCUITO PARA GRABAR Y REPRODUCIR UNA SEÑAL DE REFERENCIA (TBC) PARA SU USO EN SISTEMAS DE GRABACION/REPRODUCCION DE VIDEO INCLUYE UN CIRCUITO PARA AÑADIR A UNA SEÑAL DE VIDEO QUE VA A SER GRABADA UNA SEÑAL DE REFERENCIA TBC EN LA QUE LA SEÑAL DE REFERENCIA TBC TIENE UN PERIODO QUE VARIA ADAPTATIVAMENTE CORRESPONDIENDOSE CON UNA VARIACION DE SINCRONIZACION DE LA SEÑAL DE VIDEO; Y UN CIRCUITO PARA EXTRACTAR Y REPRODUCIR UNA SEÑAL DE REFERENCIA TBC A PARTIR DE UNA SEÑAL DE VIDEO LEIDA DEL MEDIO DE GRABACION EN ORDEN A CORREGIR ERRORES DE LA CORRIENTE DE VARIACION LINEAL EN LA SEÑAL DE VIDEO. EL CIRCUITO CORRIGE UN ERROR DE LA CORRIENTE DE VARIACION LINEAL DE LA SEÑAL DE VIDEO DE ACUERDO CON UNA SEÑAL DE REFERENCIA TBC REPRODUCIDA CON LA SEÑAL DE VIDEO A PARTIR DEL MEDIO DE GRABACION DURANTE LA OPERACION DE REPRODUCCION.
