Video Processor Description

BBG1022-2FS-OM (V1.3)
Note: Unless otherwise noted, the following functions are independently available
for Path 1 and Path 2 processing paths.
The BBG-1022-2FS video subsystem provides the functions described below.
Input Video Select/Quality Check Functions
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,
and a SD CVBS analog video input. This function also allows processed
outputs from one path to be routed to the alternate path input. For analog
inputs, waveform-based ancillary data is preserved for extraction and usage
later in the card processing chain.
The inputs 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.
frozen frame events to propagate an event alert. This alert can be used by the
card Presets function to invoke input video routing changes, GPO, and other
actions.
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 and/or burned into the output video. The function can monitor any
of the video inputs 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 or
CVBS 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 device; if the preferred format
is not detected, the device 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.
