Abstract

SE PROPONE UN PROCEDIMIENTO QUE SIRVE PARA LA TRANSMISION CONJUNTA DE SEÑALES MODULADAS DIGITALES Y ANALOGICAS DE RADIO Y/O DE TELEVISION, EN PARTICULAR EN UNA ESTACION DE CABLES DE BANDA ANCHA. EL PROCEDIMIENTO PREVE TRANSMITIR EN AL MENOS UN CANAL UNA SEÑAL DIGITAL DE RADIO Y/O TELEVISION JUNTO CON UNA SEÑAL DE TELEVISION ANALOGICA, CARACTERIZADO PORQUE EL ESPECTRO DE FRECUENCIA DE AL MENOS UNA DE LAS SEÑALES DIGITALES DE RADIO Y/O TELEVISION SE LIMITA A UNA GAMA DE FRECUENCIA INFERIOR A LA ANCHURA DE AL MENOS UN CANAL. PARA REDUCIR LA INFLUENCIA DE LA SEÑAL DE TELEVISION ANALOGICA A TRAVES DE AL MENOS UNA SEÑAL DIGITAL DE RADIO Y/O TELEVISION, AL MENOS UNA DE LAS SEÑALES DIGITALES DE RADIO Y/O TELEVISION DEBE ESTAR POR DEBAJO DE UN NIVEL DE SEÑALES PREDETERMINADO, MIENTRAS QUE EL NIVEL MAXIMO DE LA SEÑAL ANALOGICA DE TELEVISION DEBE SOBREPASAR UN VALOR PREDETERMINADO QUE ES CLARAMENTE SUPERIOR AL NIVEL DE PREDETERMINADO DE SEÑAL DE AL MENOS UNA DE LAS SEÑALES DE RADIO Y/O TELEVISION. PARA EVITAR QUE SE PRODUZCA UNA MODULACION CRUZADA ENTRE SEÑALES MODULADAS ANALOGICAS Y DIGITALES DE RADIO Y/O TELEVISION, LA AMPLITUD DEL ESPECTRO DE FRECUENCIA DE AL MENOS UNA SE LAS SEÑALES DIGITALES DE RADIO Y/O TELEVISION DEBE ESTAR POR DEBAJO DE UN VALOR PREDETERMINADO QUE DEBE SER CLARAMENTE INFERIOR A LA AMPLITUD DE LA PORTADORA DE IMAGEN DE LA SEÑAL ANALOGICA DE TELEVISION.
