Abstract

DISPOSITIVO DE REPRESENTACION DE IMAGEN INCLUYENDO CIRCUITO DE CONVERSION DE NUMERO DE CAMPO PROVISTO DE UN CIRCUITO DE CONVERSION (4) DE SINCRONISMO DE SEÑAL, EN EL CUAL EL NUMERO DE MEDIAS LINEAS EN EL CAMPO DE SEÑAL DE TELEVISION A SER CONVERTIDAS ES CONTADO POR MEDIO DE UN CONTADOR (57). ESTE NUMERO ES PASADO A OTRO CONTADOR (41) ADICIONAL EL CUAL CUENTA LA PROPORCION EN QUE SE DIFERENCIA ESTA CANTIDAD DE LA ACTUAL EN EL PRIMER CONTADOR CITADO. LA RELACION ENTRE LOS NIVELES DE CUENTA DE LOS CONTADORES ES ASUMIDA COMO IGUAL A LA RELACION ENTRE EL NUMERO DE CAMPOS DE UNA SEÑAL DE TELEVISION CONVERTIDA Y LA SEÑAL DE TELEVISION A CONVERTIR. TAMBIEN EN EL CASO DE POSIBLES DESVIACIONES DE LA SEÑAL A CONVERTIR DESDE UNA SEÑAL ESTANDAR, EL CONTADOR ADICIONAL (41) SITUA SEÑALES DE SINCRONISMO VERTICAL (V2) EN LA LOCALIZACION CORRECTA EN LA SEÑAL DE TELEVISION.FIG 1.
