摘要

A forward error correcting method in a multi protocol encapsulation-forward error correction (MPE-FEC) system, in which FEC modes are selected. The forward error correcting method includes comparing a number of received ERASUREs with a number of reference ERASUREs, selecting an ERASURE ONLY mode in which FEC is performed based on information about locations and sizes of errors, when the number of received ERASUREs is less than or equal to the number of reference ERASUREs, wherein the ERASURE ONLY mode is an FEC mode, selecting a NORMAL RS mode in which FEC is performed with respect to errors whose locations and sizes are not known, when the number of received ERASUREs is greater than the number of reference ERASURES, wherein the NORMAL RS mode is an FEC mode, and performing FEC in the selected FEC mode.
