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.
