Patent ID: 7500019

Claim:
A method for the insertion of information to synchronize a destination node with a data stream transmitted from an entry terminal in a heterogeneous network, the heterogeneous network including at least one sub-network conveying packets of a first type and one basic network conveying packets of a second type, the entry terminal being connected to the sub-network, the sub-network being connected to the basic network by means of an entry node forming the packets of the second type from at least one sub-part of at least one packet of the first type, wherein the size of the useful information of packets of the second type is independent of the size of packets of the first type, wherein, at the occurrence of at least one predetermined event, the entry node: forms a synchronization packet of the second type such that the beginning of useful information of the synchronization packet corresponds to the beginning of the packet of the first type; inserts a synchronization marker in the synchronization packet; and modifies the size of a packet of the second type preceding the synchronization packet such that the end of the useful information of said packet of the second type corresponds to the end of a packet of the first type.
