Abstract:
1. A method of transferring information signals between two separate send/receive interfaces which are part of the same communication device, the method including processing of said signals, wherein said two interfaces use, at least for information data useful to users, referred to as user data, similar transmission structures and protocols, and in particular similar formats and apply opposite processing sequences for a particular incoming signal, and wherein one of said interfaces converts modulated data into baseband data and the other of said interfaces converts said baseband data into modulated data, or vice-versa, said method also comprising the steps of: distinguishing between user data and signaling data, applying to said signaling data all processing operations needed to enable it to be interpreted by each of said interfaces, and applying to said user data only processing operations needed to transfer it from a first of said interfaces to the other of said interfaces without reconstituting or interpreting its content, wherein, when the following two processing sequences i) and ii) are applied to said signaling data: i) demodulation, burst demultiplexing, burst decomposition, decryption, and ii) source coding, channel coding, coded data interleaving, encryption, then only the following restricted processing sequences iii) and iv) are applied to said user data by the interfaces concerned: iii) demodulation, burst demultiplexing, burst decomposition, decryption, and iv) encryption.
