A dual transmission stream processing device includes an adaptor which receives a normal stream and generates an adaptation field in each packet of the normal stream; a stuffer which generates a dual transmission stream by stuffing a turbo stream into the adaptation field in a certain packet of the packets constructing the normal stream; and a supplementary reference signal stuffer which reconstructs the dual transmission stream such that a supplementary reference signal, the turbo stream, and the normal stream are combined by stuffing the supplementary reference signal into a first area which is part of the adaptation field of the packets constructing the normal stream. Accordingly, the channel status can be easily acquired as the turbo stream and the normal stream are transmitted effectively.

L'invention concerne un dispositif de traitement d'un double flux de transmission, ce dispositif comprenant un adaptateur qui reçoit un flux normal et génère un champ d'adaptation dans chaque paquet du flux normal; un dispositif de bourrage qui génère un double flux de transmission en bourrant un flux turbo dans le champ d'adaptation d'un certain paquet parmi les paquets construisant le flux normal; et un dispositif de bourrage de signaux de référence supplémentaires qui reconstruit le double flux de transmission de sorte qu'un signal de référence supplémentaire, le flux turbo et le flux normal soient combinés en bourrant le signal de référence supplémentaire dans une première zone faisant partie du champ d'adaptation des paquets construisant le flux normal. L'état du canal peut donc être facilement recueilli lorsque le flux turbo et le flux normal sont transmis de manière efficace.
