ONFIGURING THE
Description
There are two latency paths that may be used: fast
and interleaved. For either path, a forward error
correction (FEC) scheme is employed to ensure
higher data integrity. For maximum noise
immunity, an interleaver may be used to
supplement FEC.
An interleaver is basically a buffer used to introduce
a delay, allowing for additional error correction
techniques to handle noise. Interleaving slows the
data flow and may not be optimal for real-time
signals such as video transmission.
