If Closed Captions are enabled, the encoder reports whether or not it is receiving them:
•
Closed Captions: This reports Closed Caption insertion. This field will report 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.
If AFD insertion is enabled, the encoder reports whether or not it is receiving them, and what
AFD code is being inserted:
•
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.
If the input is SDI, the encoder reports the detected type of SDI signal:
