Abstract

Método para el multiplexado/demultiplexado adapativo, multiplexor/demultiplexor (MUX/DEMUX) que utiliza dicho método y elemento que lo comprende. El método comprende las etapas de realización de un primer proceso para el multiplexado/demultiplexado que posee la complejidad de la recomendación H.223; realización de un segundo proceso para el multiplexado/demultiplexado que posee por lo menos la complejidad de la recomendación H.223/Anexo A; e inserción de una o más etapas del tercer proceso para el multiplexado/demultiplexado que poseen complejidades diferentes entre las etapas (a) y (b) . El elemento MUX/DEMUX adaptativo en el sistema H.324 incluye uno o más elementos MUX/DEMUX que poseen complejidades diferentes, entre un elemento MUX/DEMUX H.223/Anexo A y un elemento MUX/DEMUX H.223. Con ello se mejora la resistencia a los errores y el rendimiento según las circunstancias.
