Introduction
9066 Functional Description
Option +LTC allows bidirectional transfer and conversion
between VBI formats over SDI and audio LTC, as well as RS-485 LTC.
Audio LTC can be received or sent over a selected balanced analog audio
input, or as digital audio over a selected embedded or AES input.
Figure 1-2 Timecode Processor
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).
