ProMPEG FEC Support for IP Streaming

G.1

Introduction

The ProMPEG Forward Error Correction (FEC) scheme is designed to recover lost
or corrupted packets caused when transferring MPEG-2 transport streams, or newer
MPEG standards encapsulated as an MPEG-2 transport streams, over an IP
network.

The MX8400 supports ProMPEG FEC to the ProMPEG Code of Practice #3 release
2 standard on both input and output ports of the ProMPEG FEC option card.

FEC packets are generated for every column and

optionally

for every row. To

generate the FEC packets, RTP frames based on their sequence numbers are
arranged in a rectangle of dimensions D * L. The payload of the FEC packet
generated is the exclusive-OR of all RTP frames in the row/column it protects.

shows the arrangement of the RTP frames and the FEC packets that

protect them.

Configuration of ProMPEG FEC Inputs

If a transport stream is protected using ProMPEG FEC, and arrives at the input of
the MX8400 ProMPEG FEC card, then the FEC streams and their parameters are
automatically detected. Hence configuration of ProMPEG FEC inputs is not
required.
