Fast Path FEC
Correction
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.
Interleaved Path
FEC Correction
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.
Fast Path CRC
Error
The number of Fast Path Cyclic Redundancy Check errors.
Interleaved Path
CRC Error
The number of Interleaved Path Cyclic Redundancy Check
errors.
Loss of Signal
Defect

Fast Path HEC
Error
Fast Path Header Error Concealment errors.
Interleaved Path
HEC Error
Interleaved Path Header Error Concealment errors.
