Abstract

EN UN PROCESO PARA LA CONVERSION DE SEÑALES DE TELEVISION DIGITALIZADAS O SEÑALES RGB DIGITALIZADAS EN UN RECEPTOR DE TELEVISION CON UNA PRIMERA FRECUENCIA VERTICAL EN UNA SEÑAL DE TELEVISION CON UNA FRECUENCIA VERTICAL DOBLE Y/O FRECUENCIA DE LINEAS DOBLE, PARA LO CUAL LAS SEÑALES DE TELEVISION O LAS SEÑALES RGB SE EXPLORAN CON UNA PRIMERA FRECUENCIA DE CICLO PARA UN PROCESADO DE LA SEÑAL DIGITAL Y LAS SEÑALES SE ALMACENAN EN UNA MEMORIA POR LO MENOS UNA DE CADA FILA Y SE SELECCIONAN CON UNA FRECUENCIA DE CICLO DEFINIDA FIJA MAS ELEVADA, PARA ADAPTACION A UNA REPRODUCCION ACOPLADA A FILAS, SE SOMETE LA SEÑAL DIGITALIZADA CON UN FILTRO DE INTERPOLACION A UNA COMPRESION O A UNA EXPANSION Y SE ESCRIBE CON LA PRIMERA FRECUENCIA DE CICLO EN LA MEMORIA.
