Dual Loop / Dual Switcher Schematic

 

 

Dual Loop / Dual Switcher, February 2, 2021

With the addition of the second Roland Switcher (found a good price on a used one, coming soon), the Device should be complete.

The first layout switched between the main Nikon feedback loop (with the two monitors and the half-mirrored glass) and the second input (which started out as just the phone, then the phone’s output on the rotating monitor, then evolved to the Canon feedback loop).

Now, the layout itself is fractal in nature, and the main switcher switches between the Nikon feedback loop (with the two monitors and the half-mirrored glass) and the Canon loop, which itself has a switcher that goes between that loop and the phone (or the phone keyed over that loop). Or, the main switcher keys that second input Canon loop (with phone involvement) over the main Nikon loop. Yikes.

Once again I’m not sure what all this will look like, and once again I’m posting before it’s all setup and ready to go, because, ya never know.

Notes:

Preview Out of the Roland Switcher is just used to access the Switcher settings.

I’m using the Blackmagic Video Converter in place of a simple HDMI to SDI converter to see what effect a delay caused by converting from one video format to another will have on the feedback loop.

A 1 in 3 out HDMI splitter could replace the two HDMI splitters in the Secondary Loop, and an HDMI splitter could be used in the Main Loop.

This is an updated schematic that puts the Phone back on the Rotating Monitor (I had somehow forgotten about that aspect). Now, the Canon sees the Phone’s output on the rotating Panasonic Monitor when Switcher 2 is on Source 2, then when switched to Source 1, the Canon sees its own output on the Rotating Monitor. Switching quickly between Source 1 and 2 will have the effect of the Phone's image going into a feedback pattern.

On the Main Loop, when the Panasonic Monitors are on Input 2, they show the Nikon when Switcher 1 is on Source 1. When Switcher 1 is on Source 2, they show the Secondary Loop. Switching quickly between Source 1 and 2 will have the effect of the Secondary Loop going into a feedback pattern.
