IR receivers - plasma filters?

[Paul Gale <groups2@xxxxxxxxxxxxxxxx>]

I've finally got round to re-implementing my house-wide IR receiver
network (using my Russound CAV6.6 amps with built in IR network). Trouble
is, the plasma and one of the bedroom LCD TV's create havoc with the IR,
pumping out so much interference that the IR network is unusable :(

I know manufacturers like Russound and Xantech etc produce plasma friendly
IR receivers but they sell for quite a premium.

Looking at the Russound products, they state that they use "optical
filtering" to reject the interference.

Anyone know how this can be achieved via the DIY route? Is it just a filter
window or a particular type of IR receiver LED or both?

Ideally, I'd like to incorporate this into my existing Russound wall
keypads, replacing the standard receiver - that way I don't have a bulky
second box next to it or elsewhere in the room.

Thanks,

Paul.
