Abstract

UN MÉTODO PARA SINCRONIZAR DATOS DE UN CONTENIDO INTERACTIVO CON EL AUDIO Y VIDEO DE UNA TRANSMISIÓN DE TELEVISIÓN DIGITAL. EL MÉTODO COMPRENDE LA EJECUCIÓN DE UNA APLICACIÓN PARA TELEVISIÓN DIGITAL QUE REALIZA LA SINCRONIZACIÓN Y LA APLICACIÓN PARA RECIBIR EVENTOS DE SINCRONIZACIÓN ES ENVIADA POR LA RADIODIFUSORA, Y QUE ES<br /> REGISTRADA COMO OYENTE DE EVENTOS DE UN OSM-CC CON MENSAJES DE EVENTO QUE DEFINE LOS VALORES DE UN CONTADOR QUE INCLUYE VALORES EN SECUENCIA CORRESPONDIENTE A LA SINCRONIZACIÓN ENTRE EL CONTENIDO INTERACTIVO Y EL AUDIO Y/O VIDEO; Y VALORES DEL INTERVALO DE TIEMPO QUE DECIDE CUANDO LA APLICACIÓN EJECUTADA COMPRUEBA SI EL CONTENIDO INTERACTIVO ESTÁ SINCRONIZADO CON EL AUDIO Y/O VIDEO;<br /> IDENTIFICAR EL VALOR DE EN SECUENCIA CORRESPONDIENTE A LA SINCRONIZACIÓN Y EL VALOR DEL INTERVALO DE TIEMPO, ENVIADOS POR LOS MENSAJES TRANSMITIDOS VIA OSM-CC; INICIAR UN CRONÓMETRO Y UN CONTADOR PROPIO; Y SINCRONIZAR LOS DATOS DE CONTENIDO INTERACTIVO DE LA APLICACIÓN EJECUTADA CON EL AUDIO Y/O VIDEO DE LA TRANSMISION DE TELEVISIÓN DIGITAL, DE ACUERDO CON EL VALOR ENVIADO POR EL EVENTO DE FLUJO DEL DSMCC EN CADA INTERVALO DE TIEMPO PREDETERMINADO; DONDE LA APLICACIÓN EJECUTADA ES CAPAZ DE MANTENER CONTEO CRECIENTE  DE LOS VALORES DE SECUENCIA Y MANTENER LA COMPROBACIÓN DE LA SINCRONIZACIÓN EN EL MISMO INTERVALO DE TIEMPO INFORMADO POR LOS EVENTOS DE FLUJO DEL DSM-CC, AUN CUANDO NO HAY SEÑAL, A TRAVÉS DEL CRONOMETRO Y EL CONTADOR INICIADOS.<br />
