Closed Captioning Processor
This function provides support for closed captioning setup. The function
allows the selection of the ancillary data line number where the ancillary
closed caption data is outputted when the output is HD. When receiving
HD-SDI, both CEA 608 and CEA 708 are supported, with CEA 608 and
CEA 708 (containing CEA 608 packets) converted to line 21 closed
captioning on outputs down-converted to SD.
