Introduction
BBG-1034-AUD-PRO-DSP Functional Description
Video Processor Description
The BBG-1034-AUD-PRO-DSP video subsystem provides the functions
described below.
Input Video Select/Quality Check Functions
A GUI-based control allows the device to select from up to four 3G/HD/
SD-SDI inputs, and a SD CVBS analog video input. For analog inputs,
waveform-based ancillary data is preserved for extraction and usage later in
the device 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 device
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
Event Setup function to invoke video routing changes, GPO, and other
actions.
Video Output Crosspoint
A four-output video matrix crosspoint allows independently applying the
processed video output or reclocked input to any of the four discrete coaxial
outputs (
SDI OUT 1
thru
SDI OUT 4
). For an SD output, a CVBS coaxial output
is available as a processed video output.
