Figure 1-4 Timecode Processor
Closed Captioning Processor
This function provides support for closed captioning setup. When enabled,
the function allows passage of timecode data. When up-conversion from SD
to an HD is active, the function converts waveform-based timecode data to
packet-based timecode 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).
Wings Insertion
Option
+WINGS
allows a symmetrical L-R wings insertion to be integrated
into the card program video output. Wings video is accommodated using a
separate wings SDI input. The wings user interface displays wings timing
relative to the card output video, allowing wings timing offset to be adjusted
such that wings can be properly framed. (The option and its host card does not
provide timing offset control of the wings video; offset must be provided by a
external frame sync card or device controlling the wings video feed.)
The wings L/R insertion width can be manually configured, or can be set to
automatically track with aspect ratio as set by the host card (on cards
equipped with aspect ratio control).
