Abstract

UNA ESTACION DE DIFUSION DIGITAL (5) SE CONFIGURA PARA "DEVOLVER" Y AÑADIR PROGRAMACION INTERACTIVA A UNA SEÑAL DE TELEVISION TRANSMITIDA POR UNA RED REMOTA (10). ANTES DE TRANSMITIR LA SEÑAL DE TELEVISION, LA RED REMOTA INSERTA UN DISPARADOR DENTRO DEL INTERVALO VERTICAL EN BLANCO DE LA SEÑAL. EL DISPARADOR CONTIENE INFORMACION DE COMANDOS PARA CONTROLAR LA CARGA Y REPRODUCCION DE UN PROGRAMA INTERACTIVO DESIGNADO. DESPUES DE COMBINAR EL DISPARADOR CON LA SEÑAL DE TELEVISION, LA SEÑAL COMBINADA SE MODULA Y SE TRANSMITE DESDE LA RED REMOTA A TRAVES DE UN ENLACE DE SATELITE (62). ESTA SEÑAL COMBINADA SE RECIBE EN LA ESTACION DE DIFUSION DIGITAL DONDE SE DIGITALIZA Y SE ENRUTA A TRAVES DE UNA RED DE VIDEO PARA LA ASIGNACION DE CANAL Y OTROS PROCESOS. DESDE LA RED DE VIDEO, LA SEÑAL DE TELEVISION DIGITALIZADA SE ENVIA A UN DESCODIFICADOR VBI QUE EXTRAE EL DISPARADOR. EL DISPARADOR EXTRAIDO SE ENVIA A UN ADMINISTRADOR Y SERVIDOR DE FLUJO INTERACTIVO PARA CONTROLAR LA CARGA O REPRODUCCION DE UNPROGRAMA INTERACTIVO IDENTIFICADO POR EL DISPARADOR. EL RESTO DE LA SEÑAL DE TELEVISION DIGITALIZADA SE ENVIA A UN CODIFICADOR DE VIDEO DONDE SE COMPRIME. UNA UNIDAD DE GENERACION AVI DE LA ESTACION DE DIFUSION DIGITAL COMBINA ENTONCES LA SEÑAL DE TELEVISION COMPRIMIDA Y EL PROGRAMA INTERACTIVO PARA FORMAR UNA SEÑAL AVI QUE SE DIFUNDE A LOS USUARIOS FINALES POR MEDIO DE UN ENLACE POR SATELITE.
