    How to do wire synchronization for an infra red TX RX pair, so that the receiver would not turn on when it receives signal from a different IR transmitter?

    You'll need to have an Authentication process so that the receiver knows that the signals it's getting is from the right source before it Responds.

    It's the way standard remote controls work. The receiver only responds to a control code if is recognized by the receiver decode electronics. Thus codes from other remotes are ignored.
