Abstract
Procedimiento de multiplexado para la comunicación multimedia, que es compatible con el protocolo H.223 por medio del cambio de un cabezal de una unidad de datos de protocolo de multiplexado (MUX-PDU), que incluye las etapas de codificar datos de los media, y multiplexar los datos de los media codificados en la etapa (a) en unidades de un marco predeterminado, e introducir una segunda bandera de longitud predeterminada con una autocorrelación en el marco después de una primera bandera que presenta la apertura y el cierre del marco, con lo cual se aumenta la probabilidad de detectar la MUX-PDU por medio de un receptor mediante la adición de una bandera que presenta una alta autocorrelación al marco de la MUX-PDU del protocolo H.223, aumentando de este modo la flexibilidad respecto a errores.
