Abstract

PROCEDIMIENTO PARA LA EMISION EN TIEMPO SINCRONO DE INFORMACIONES POR VARIAS EMISORAS DE ONDA SINCRONIZADA. EN LA CENTRAL (Z) SE RETIENEN LAS INFORMACIONES A EMITIR EN UN ALMACEN (S), Y DESPUES, SE ENTREGAN A LAS DIFERENTES EMISORAS DE ONDAS SINCRONIZADAS (GWS1 ... GWSN). ALLI QUEDAN RETENIDAS EN ALMACENES RESPECTIVOS (S1 ... SN) DURANTE UN TIEMPO DE ESPERA, Y AL MENOS HASTA QUE LAS INFORMACIONES HAYAN RECORRIDO EL CAMINO DE MARCHA MAS LARGO POSIBLE. DESPUES DEL TIEMPO DE ESPERA SE EFECTUA, MEDIANTE UNA SEÑAL DE COMPAS, LA LLAMADA SINCRONA DESDE LOS ALMACENADORES (S1 ... SN) Y LA EMISION SINCRONA A TRAVES DE LAS EMISORAS SINCRONIZADAS.
