Configuring Forw ard Error Correction Settings
Due to its nature (occasionally packet loss, packet reordering, and/or stream jitter) a
traditional IP network is not the perfect channel for transmitting broadcast -quality
compressed video content. Forward Error Correction (FEC) developed by the Pro-
MPEG forum is a unique technology to enhance the robustness of video traffic over
IP networks. The D9824 supports Pro-MPEG FEC Code of Practice (COP) #3 release2
and SMPTE-2022, which is based on the exclusive or (XOR) boolean operator applied
to a number of data packets. When a FEC packet is created by performing the XOR
boolean operation on a number of RTP packets, a missing RTP packet can always be
reconstructed by performing the XOR operation on the FEC packet and the
remaining RTP packets.
FEC = RTP1 XOR RTP2
RTP1 = FEC XOR RTP2
RTP2 = FEC XOR RTP1
