Abstract
SISTEMA DE VIDEOTEX. ESTE SISTEMA TIENE UN CENTRO DE EMISION (2) CON UN MEDIO DE COMPOSICION (6) DE UNA REVISTA DE PAGINAS CON FILAS DE CARACTERES QUE PASAN A UN CIRCUITO DE TRATAMIENTO Y MEMORIZACION (8) DE SEÑALES NUMERICAS AGRUPADAS EN OCTETES DE DATOS Y OCTETES DE MANDO; EL CONJUNTO ESTA UNIDO A UN MULTIPLEXADOR (12) ENCARGADO DE DAR LAS INFORMACIONES EN LAS LINEAS DE UNA SEÑAL DE TELEVISION. LAS SEÑALES EMITIDAS POR LA ANTENA (16) LLEGAN AL CIRCUITO DE RECEPCION Y DEMODULACION (20) QUE LAS MANDA AL ORGANO DE VISUALIZACION (30), POR MEDIO DE LAS VIAS DE TRATAMIENTO DE LAS SEÑALES NUMERICAS (22) Y DE SEÑALES VIDEO DE IMAGEN (28).
