A multiprotocol encapsulation (MPE) encapsulator ( 6 ) receives or generates a copy or partial copy ( 10 ') of service information data ( 10 ) and generates associated forward error correction (FEC) data. In addition to transmitting service information data in a conventional way via a first set of channels, the MPE encapsulator transmits the copy 10' and the associated FEC data via a second set of channels.
