I would like you to send me an infrared transmitter receiver circuit with relay outputs. I have tried a design using LM741 and LM567 on the receiver side with one relay, it works okay. But now, I am required to have two different relay outputs. You may include the PIC it's okay.
i think u r making the whole thing complex. if u know about the 555 timer then it is easy to make the circuit using that. selecting proper receiver like tsop1738 module, u can detect the ir signal. the output of the TSOP can be connected to a buffer IC like uln2003 (in sinking mode) to control relays.
and this site may be helpful to you. for two frequencies detection or transmitter connect different resistances series with switches in 555 circuit and use two TSOP s of transmitting frequencie http://www.lpilsley.co.uk/cybot/radar.htm

i agree to krishna but still if u want to use realy as output u can do it on a 555 with 2 realys connected at out put drived by the same ir
u want a microconteoller to be used then it is simple
use tsop1738 with RC at a microcontroller i/p pin
decode than the ir wavelenght ussing a softweare controll as many devices u like
