Closed Captions:
This reports Closed Caption insertion. This field will report either
Present
or
Not Present
. If Closed Captions are reported as
Not Present
, the possible
reasons are:
o
If the caption source is EIA-608 Line 21, it means that the encoder cannot find a
valid closed caption waveform on that line.
o
If the caption source is SMPTE-334 VANC, it means that the encoder is either not
receiving closed caption messages, or it is receiving EIA-708 messages without a
caption field.
Note that it is possible for the encoder to be receiving closed caption data that is empty
(without actual captions). These will be reported as
Present
.
AFD:
This reports AFD insertion. This field will report either
Not Present
(if no AFD is
being received) or
Code XXXX
, if AFD is being received; XXXX is the current AFD
code being inserted. If AFD Source is set to Manual AFD Selection, this field will report
the selected manual code.
HDR Metadata:
This field will report either
Present
or
Not Present
, depending on
whether or not HDR metadata is being detect in the video signal.
SCTE 104 to SCTE 35 Injection:
this function includes the following three indicators in
the tab:
o
SCTE 35 Packets Injected:
shows a count of how many SCTE 35 packets have
been successfully injected in the transport stream for this encoder. Successful
SCTE 35 injections are also logged, see the Admin Event Log Tab.
o
SCTE 35 Packets Dropped:
if there are too many SCTE 104 messages, it may
not be possible to insert all the SCTE 35 packets due to internal limitations in the
9992-ENC. The 9992-ENC can insert up to 10 SCTE 35 packets per second,
which is sufficient for all usual ad insertion applications. If this indicator is
nonzero, contact Cobalt Digital.
o
SCTE 104 Errors:
shows a count of SCTE 104 errors in the incoming signal. A
nonzero count indicates that the device upstream of the 9992-ENC is non-
compliant. Contact the vendor of that equipment.
SMPTE 2038:
this function includes the following two indicators in the tab:
o
SMPTE-2038 Injection Rate:
shows the current average injection rate for ANC
packets carried using SMPTE-2038, over the last 2-second interval. This can be
used to set the maximum injection rate.
