| 摘要 |
The invention concerns a device (D) for processing data streams in a satelli te communication of a communication network. Said device (D) comprises processi ng means (MT), upon receiving a first incoming data stream whereof the carrier has a first modulation and comprising in selected locations selected inserti on blocks, i) for detecting the insertion blocks and at least one characteristi c of the carrier of the first incoming stream, selected among its frequency, i ts phase its rhythm and its amplitude, ii) for modulating in accordance with th e first modulation and taking into account each detected characteristic, data packets to be transmitted to a common destination with that of the first incoming stream, and iii) for replacing with the modulated packets some at least of the insertion blocks detected in the first incoming stream which ha s not been modulated, so that the resulting stream is transmitted by the satellite, with its first original modulation, to the common destination to be demodulated therein as if it had been constituted by a single modulator.</SD OAB>
