These errors result in the transmission error flags
EDH
and
EDA
and the non-transmission related flags
IDH
and
IDA
.
In Figure 9, the AES/EBU audio encoder has generated an
error during the audio formatting process and reported an
IDH
(Internal device error Detected Here) error.
The signal from the audio encoder then experiences
degradation from a faulty cable, before it reaches the router.
In this case, the cable is marginal and is producing random
infrequent errors. A GS9001 device in the router flags these
errors as
EDH
(Error Detected Here) for Active Picture, Full
Field or both. Incoming
IDH
flags are also recoded as
IDA
(Internal device error Detected Already).

The next device in the chain is a distribution amplifier (DA)
which is receiving its input from the router. The GS9001 device
in the DA will recode the incoming
EDH
flag as
EDA
(Error
Detected Already) and pass the
IDA
flag.
An additional transmission error occurs between the DA and
the production switcher which is flagged as
EDH
. The GS9001
in the production switcher now has a list of error flags that can
be reported locally or through a communications interface to
a central maintenance station.
