AJA FS2 - SDI2 Input Protect

In 1080p50/60 mode, the system always assumes that the input is a single 1080p50/60
signal (even if there is SMPTE 352 data to the contrary).
In D
ual Stream mode, the system always assumes (even if there is SMPTE 352 data to the
contrary) that the input consists of two multiplexed independent 3G video streams. The
signals are demuxed as shown.

5 SDI2 Input Protect This parameter allows you to protect Input SDI 2 from being taken by a Dual Stream
selection made with parameter 4 above.
In the Nor
mal setting (default), the SDI 2 video signal always comes from the SDI 2
physical input. Choosing Auto Detect or Dual Stream in parameter 4 does not switch away
from the physical input.
In the D
ual Stream setting, the FS2 assumes both channels of Dual Stream 3G video are
muxed onto a single wire at the SDI1 input. The SDI 2 video signal is then taken internally
from the SDI 1 Stream 2 signal instead of the SDI2 In connector.
The following table shows the selec
tions and their results. In the table, SDI1-1 and SDI1-2
are the two muxed streams entering the SDI1 Input.

SDI2 cannot be used by Dual Stream 3G SDI video on SDI Input 1.
Allows SDI2 to be used by a Dual Str
