Forward Error Correction (FEC) is available for MPEG2TS streams only. FEC is configured
at the stream level and at the transmitter level. This topic explains how to configure FEC at
the stream level only. To configure it at the transmitter level see the Enable Forward Error
Correction (FEC) on a Transmitter topic.
FEC is a type of digital signal processing that improves data reliability by introducing a
known structure into a data sequence prior to transmission or storage. This structure enables
a receiving system to detect and possibly correct errors caused by noise and interference. As
the name implies, this coding technique enables the decoder to correct errors without
requesting retransmission of the original information. For detailed information about
VBrick's implementation of FEC see the Forward Error Correction (FEC) Theory of
Operation topic.
Note: If using FEC you may choose to
