Abstract:
1. Device for inserting error correcting codes into at least one data stream intended to be sent as packets in a network, each of said streams including reference resynchronization indicators dispersed in said stream and the data lying between any two of said consecutive resynchronization indicators constituting a data block, said device for inserting codes comprising: a unit for determining successive data segments in said streams, and a unit for allocating a set of error correcting codes to each of said segments, said sets of codes having variable sizes depending on said segments, characterized in that said insertion device also comprises a unit for identifying said resynchronization indicators, and in that the unit for determining segments is designed to determine the segments by performing partitions of said data blocks and in that the allocating unit is designed to assign decreasing sizes to said sets of codes between any two of said consecutive resynchronization indicators.
