9980-CSC-3G Functional Description
Figure 1-1 shows a functional block diagram of the 9980-CSC-3G. In addition
to a YCbCr proc features with RGB processing controls color corrector, the
9980-CSC-3G includes an advanced frame sync/pattern generator.
9980-CSC-3G Input/Output Formats
The 9980-CSC-3G provides the following inputs and outputs:
•
Inputs:
•
3G/HD/SD SDI IN A thru SDI IN D
– four 3G/HD/SD-SDI inputs.
SDI IN A
or
SDI IN B
can be set to failover to
A
or
B
in absence of
opposite channel of this pair.
•
Outputs:
•
3G/HD/SD-SDI OUT (1-4)
– four 3G/HD/SD-SDI buffered video
outputs. Each output can be independently set as processed output
video or selected input video reclocked.
Input Video Select Function
A GUI-based control allows the card to select from up to four 3G/HD/
SD-SDI inputs.
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 card
when selected as a choice on the output crosspoint.
Video Output Crosspoint
A four-output video matrix crosspoint allows independently applying the card
processed video output or reclocked input to any of the four card discrete
coaxial outputs (
SDI OUT 1
thru
SDI OUT 4
).
Using the appropriate rear module, an additional output (
RLY BYP B
) provides
a relay-protected output that outputs a copy of
SDI OUT 1
crosspoint selection
in normal operation. In power loss failover
RLY BYP B
passive outputs the
signal connected to
SDI IN B
.
