Out of curiosity, is there a way to enable the legacy VT5 as a NDI source?

The VT5 is on Win7 machine and I am planning to use a Macbook Pro as the OBS/streaming machine, same network, same house, different room (mainly because the VT5 machine is noisy).

Would the NDI software tools allow this? (it seems that NDI is a more advanced version of iVGA).

Or would I need something a couple of converters ( VT5 Analog to SDI/HDMI) and (SDI/HDMI to NDI) like the Newtek Connect Spark?
