Abstract
There is provided an apparatus for enabling recovery of missing information in a digital communication system. The apparatus includes a Forward Erasure Correction (FXC) encoder for computing FXC parity superpackets across information superpackets for subsequent recovery of any entire ones of the information superpackets that have been at least partially comprised due to synchronization loss.

An apparatus for enabling recovery of missing information in a digital communication system, comprising:
- a Forward Erasure Correction (FXC) encoder for computing FXC parity superpackets across information superpackets for subsequent recovery of any entire ones of the information superpackets that have been at least partially compromised due to synchronization loss;
- and
- a multiplexer for multiplexing the information superpackets and the FXC parity superpackets prior to any transmission thereof.
An apparatus for recovering missing information in a digital communication system, comprising:
- a Forward Erasure Correction (FXC) decoder for decoding FXC parity superpackets previously computed across information superpackets to recover any entire ones of the information superpackets that have been at least partially compromised due to synchronization loss;
- wherein said FXC decoder further decodes FXC sync transport packets to determine superpacket sequence numbers and superpacket positions for both the FXC parity superpackets and the information superpackets.
