This control determines whether closed captions will be encoded on line 21
according to EIA 608B on the program SDI and broadcast analog outputs.
The encoding of captions on the monitor analog output is set by the Mon CC
Enable/Disable menu item on the Output Picture menu.
Set the control to Off to disable closed caption encoding.
Set the control to On to encode closed captions that have been extracted
from SMPTE 334M VANC data on the incoming HD video.
This control determines whether vertical interval time code (VITC) will be
inserted on the program SDI and broadcast analog outputs. 525 VITC Line
and 625 VITC Line menu items set the insertion line for the VITC. The time
bits will be converted from the RP188 ancillary time code on the HD Video
input. The User bits can be set to the original time or user bits by the VITC
User Bits menu item.
This control determines whether VITC User bits will contain the original time
numbers or the original user bit numbers. The VITC generator must be
enabled using the VITC Generator menu item.
When the incoming video is at a different frame rate than the
downconverted video, it is often useful to carry the original time code
information in the VITC user bits.
For other applications it is necessary to carry the user bits from the
incoming time code into the VITC User Bits.
This control determines the line number where VITC will be inserted in 525
line video when the VITC Generator control is set to On.
