Patent ID: 7940197

Claim:
Network re-encoding method for re-encoding encoded symbols to be transmitted to at least one communication equipment (CE) connected to a network, comprising the step of re-encoding output nodes, defined by LT code symbols representative of encoded symbols and representative respectively of the results of XOR Boolean operation(s) between input nodes defining decoded symbols whose values have to be discovered and to which they are linked into a Tanner graph, by combining chosen input node(s) and/or output node(s) having known values and called partially decoded nodes, in order to produce new LT code symbols defining generated output nodes ready to be transmitted; wherein during said combining step one combines said partially decoded nodes by means of XOR Boolean operations therebetween; and wherein during said combining step one starts by determining among degrees of a current distribution of degrees of the generated output nodes the one having the highest difference with a same degree of a first chosen reference distribution, and which allows to produce a generated output node having this degree, then one produces a generated output node having this degree by combining at least one partially decoded node.
