Abstract
REJILLA DE CONMUTACION PARA LA DISTRIBUCION EN M SALIDAS A ELEGIR DE UNA SEÑAL SELECCIONADA ENTRE N SEÑALES DIRIGIDAS POR TANTO A LAS ENTRADAS EN LA REJILLA, CADA UNA DE LAS M SALIDA PUEDE A VOLUNTAD SE CONMUTADA EN UNA DE LAS N ENTRADAS EN FUNCION DE UNA SEÑAL DE TELECOMANDO. SE CARACTERIZA POR COMPUTAR UNA ESTRUCTURA DE SOPORTE (2) PARA UN CONJUNTO DE TARJETAS DE ENTRADA (1) QUE RECIBEN CADA UNA UNAS SEÑALES DE VIDEO (V), EN NUMERO CORRESPONDIENTE A UN SUBMULTIPLO DADO EL NUMERO TOTAL DE SEÑALES N A TRANSMITIR; AL MENOS UN CONJUNTO DE TARJETAS DE CONMUTACION (3), EN EL QUE CADA UNA SE REUNE CON UNA TARJETA DE ENTRADA (1); Y, AL MENOS UN SUBCONJUNTO DE TARJETAS DE SALIDA (5), TODAS REUNIDAS EN EL CONJUNTO DE TARJETAS DE CONMUTACION (3) Y LIBERANDO, CADA UNA, UNA SEÑAL CUALQUIERA SELECCIONADA ENTRE LAS SEÑALES RECIBIDAS POR CADA TARJETA DE CONMUTACION. LAS TARJETAS DE CONMUTACION TIENEN UN CONJUNTO DE CELULAS DE ENTRADA (E) MONTADAS EN PARALELO, EN NUMERO IGUAL AL SUBMULTIPLO QUE DEFINE EL NUMERO DE SEÑALES VIDEO A TRANSMITIR Y EN CONJUNTO DE CELULAS DE SALIDA (S); CADA CELULA DE ENTRADA Y CADA CELULA DE SALIDA ESTA REUNIDA POR UNA CELULA DE CONMUTACION (C), DEJANDO PASAR UNA SEÑAL SELECCIONADA DE ENTRADA HACIA LA SALIDA POR EFECTO DE UNA ORDEN DE COMANDO.
