Double trouble with remotes...

Two identical television tuners next to each other feed different programming to one television, on ports HDMI 1 and HDMI 2 .

As the tuners are identical, only one remote is needed/used. With both tuners on, both respond to the remote simoultaneously.

Enabling a HDMI port allows receiving the wanted tuner signal, but the remote acts also on the other sending it off the previously selected channel.

Any clever way you may come up with, to select/choose which one of the tuners should obey, and the other to ignore the commands ?

Nope.. ;)
If both respond to the same signal (and cannot be changed to a different code set) then you are SOL...

IR or RF remotes?

One might be able to cobble up a "wall/blocker" and when you are standing to the left the left TV would work and standing to the right the right TV would respond.. goofy yes..

There is probably an aftermarket device to accommodate that..

Can you place a servo activated shutter in front of the ir receivers controlled by a separate ir receiver circuit, and either use a code from your current remote, or a completely different remote to toggle the shutter?

Or the same principal, but instead of a shutter, use a relay and a single ir receiver and toggle which box gets connected to the ir receiver?
