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.
EDH works as per
specifications
