EDH works partially, converts edh errors to
eda, does not report all errors

·

Gennum chip modifies EDH data in
incoming SDI stream

·

If EDH is not present in incoming stream,
Gennum chip inserts it; therefore the
Encoder thinks EDH was there all along.
Error detection in this case is unreliable as
the CRCs and checksums are calculated
AFTER the errors have occurred.

·

If EDH is present in incoming stream (the
most likely scenario) the Gennum chip
detects CRC and checksum errors (edh),
turns those errors into edas and recalculates
CRCs. In this case the Encoder reports the
wrong type of errors, which would make
fault-finding very confusing for an operator
trying to find a fault in the SDI chain.
