Introduction
BBG-1002-UDX-FS Functional Description
Video Processor Description
Note: Unless otherwise noted, the following functions are independently available
for Path 1 and Path 2 processing paths.
The BBG-1002-UDX-FS video subsystem provides the functions described
below.
Input Video Select/Quality Check Functions
Used in common as a routing source for both
Path 1
/
Path 2
is a GUI-based
control that allows selecting 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 processing chain.
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
Allowed Rasters
and
Allowed Frame Rates
filter
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 unit when
selected as a choice on the output crosspoint.
(Option +QC)
. Quality Check allows criteria such as black/
frozen frame events to propagate an event alert. This alert can be used by the
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 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 unit; if the preferred format is not detected, the
unit 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.
When licensed with option
+LTC
, this function also can
receive, send and translate between audio/RS-485 LTC timecode formats and
the VBI formats described above.
