Closed Captioning Processor

This function provides support for closed captioning setup. When enabled,
the function selects from current input video, analog SD, or SDI as the source
of closed captioning data. The function also 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 (on up-convert of SD, only CEA 608 closed captioning is generated).

Metadata Extractor/Re-inserter

This function extracts and preserves Dolby

®

metadata from the input SDI, and

in turn allows the metadata to be re-inserted in the output SDI. This allows
scaling and/or format conversions without losing Dolby

®

metadata. (The

9061 does not offer Dolby

®

decoding or encoding, but will pass Dolby

®

E

and/or Dolby

®

Digital™ encoded signals and metadata intact.) The extracted

metadata is buffered and then output on a user-selectable line number on the
SDI output, and on the

RS-485 I/O

connector (on cards equipped with

appropriate Rear I/O Module).
