<p>Method, relay node and computer program product for processing transport packets, the transport packets conveying: (i) data stream units forming a data stream, and (ii) correction data units relating to the data stream units, where each transport packet contains information identifying the content of units in that transport packet. Transport packets are received at the relay node, the data stream units in the transport packets received at the relay node being insufficient to constitute the data stream. At least some of the correction data units and the data stream units in the received transport packets are used to generate substitute data stream units thereby to substantially recover the data stream at the relay node. The relay node packetises the data stream units of the substantially recovered data stream with correction data units to form output transport packets for transmission from the relay node, and then the output transport packets are transmitted from the relay node.</p> |
