Patent ID: 8116255

Claim:
A data stream processing device for a communication satellite of a communication network, comprising: processing means arranged, in an event of receipt of a carrier modulated with a first incoming data stream using a first modulation and the first incoming data stream comprising at chosen locations insertion blocks, i) to detect said insertion blocks and at least one characteristic of the carrier of said first incoming data stream, chosen from among an amplitude, a frequency, a phase and a timing, ii) to modulate, in accordance with said first modulation and based on each detected characteristic, data packets to be transmitted to a common destination with a destination of the first incoming data stream, and iii) to replace one or more of said insertion blocks detected in said carrier modulated with the first incoming data stream with said modulated packets so that the carrier modulated with the first incoming data stream and said modulated packets are transmitted with said first modulation by said satellite to said common destination.
