Abstract

SE COMPONE EL DESEO DE OFRECER A LOS PARTICIPANTES DE UNA RED DISTRIBUIDORA DE TELEVISION POR CABLE, JUNTAMENTE CON EL SERVICIO PARA ESTA TELEVISION POR CABLE DE UN VIDEO DE LLAMADA. EL TIEMPO DE LA PARTE DEL CONDUCTOR DE FIBRA OPTICA DE LA RED DISTRIBUIDORA DE LA TELEVISION POR CABLE NO ALCANZA AL PARTICIPANTE (111), SINO QUE SE TERMINA EN EL CIERRE (ONTJ) DE RED OPTICA Y DE ALLI RESPECTIVAMENTE SE AJUSTA A TRAVES DE UNA RED (108 DAD DE LAS SEÑALES DE VIDEO INDIVIDUALES DE LOS PARTICIPANTES PUEDEN SER TRANSMITIDAS A LOS PARTICIPANTES, CON ELLO PUEDEN RECIBIR RESPECTIVAMENTE LAS SEÑALES DE VIDEOLLAMADAS. DE ACUERDO CON LA INVENCION SE CONSIGUE LA TRANSMISION A PARTIR DE LA CENTRAL (100) DIGITAL EN SISTEMA MULTIPLEX DE TIEMPO Y MULTIPLEX DE ONDA A TRAVES DE LA RED (101-107) DE DISTRIBUCION DE CONDUCTOR DE FIBRA OPTICA HASTA LA DESCONEXION OPTICA (ONTJ). EN CADA CIERRE DE RED OPTICA SE CONSIDERA SI UNA PARTE DE LA SEÑAL DE VIDEO INDIVIDUAL DEL PARTICIPANTE, QUE DETERMINA PARA EL PARTICIPANTE,ESTA CONECTADA EN LA CONEXION (ONTJ) DE RED OPTICA. LAS VIDEOSEÑALES INDIVIDUALES DEL PARTICIPANTE EXTRAIDAS SON TRANSMITIDAS DE FORMA MODULADA (M1-M6) Y GUIADAS CONJUNTAMENTE EN SISTEMA MULTIPLEX DE FRECUENCIA DE LAS SEÑALES DE TELEVISION POR CABLE, QUE SON DISTRIBUIDAS SOBRE LA RED (108110) DE CONEXION ELECTRICA A LOS PARTICIPANTES (111) CONECTADOS AL CIERRE (ONTJ) DE RED OPTICA.
