Video Processor Description

BBG-1002-2UDXDI-OM (V1.0)
Note: Unless otherwise noted, the following functions are independently available
for Path 1 and Path 2 processing paths.
The BBG-1002-2UDX-DI video subsystem provides the functions described
below.
Input Video Select
Used in common as a routing source for both
control that allows the card to select from up to four 3G/HD/SD-SDI inputs.
This function also allows processed outputs from one path to be routed to the
alternate path input.
The input can be selected using DashBoard manual control, set to failover to
an alternate input upon loss of the target input, and can be externally selected
via a GPIO interface. An input
allows inputs to be filtered (screened) for only user-allowed raster sizes and
frame rates, with unallowed raster/rates being rejected as an input (input
unlock). Reclocked copies of any SDI input can be outputted by the card
when selected as a choice on the output crosspoint.
Timecode Processor
(See Figure 1-2.) This function provides for extraction of timecode data from
input video source, and in turn allow individual timecode strings to be
embedded into the output video. The function can monitor any of the video
inputs of the card for supported timecode formats such as ATC_LTC or
ATC_VITC for down-conversions to HD, and ATC_VITC or VITC
waveform (with selectable odd/even field line number control) for SD SDI
inputs. Waveform VITC timecode can also be extracted from a reference
input and used as the output timecode value. If the preferred format is
detected, the preferred format is used by the card; if the preferred format is
not detected, the card uses other formats (where available) as desired. An
internally-generated free-run timecode can be also be embedded on output
video if desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
receive, send and translate between audio/RS-485 LTC timecode formats and
the VBI formats described above.
