IR remote control conflict

2 different makes of set-top box mutually affected on some controls between
each controller.
Extending the IR LED out by 2x 20 foot wires and fitted over the Rx of its
associated box - would that work? going back to the days of wired r/c.
Any other ideas - eg differently angled matt black shrouds of each Rx

Try Fibre Optics?

Why not just put the boxes at a substantial distance from each other? This
should prevent them from seeing the "wrong" control.

I wish you would learn how to write a simple declarative sentence. Is this
too much to ask? I'm tired of having to struggle through your posts.

Any particular maker and model of set-top box? Cable? Satellite? IP
Video? Game machine? Most of these have provisions for multiple such
things in the form of settings for "remote 1" and "remote 2". At
least my DirecTV and Comcast supplied boxes do that.


Sigh. Yeah, that would work, but it's messy, ugly and not very
wireless.

If your remote controls have a single IR LED for an emitter, just
replace it with a 940 nm IR LED that has a very narrow beam, or one
that is lens focused. If the boxes are sufficiently seperated, there
should be no interaction. You could also move closer to the boxes,
but that's too easy.

Some red LED's also belch enough nera IR to activate a remote
receiver, especially when focused.

Of course, if all you want to do is channel surf, then there are
dedicated remote controls that should suffice:

One advantage of wired remotes is they do not get lost down the sofa or end
up in another room, you can always follow the wire. As long as there is a
non-trip-over route for the wire.
Then I suppose increasing the dropper R for the LED rather than insulation
tape IR attenuator then rare battery replacement required.

The simplest and cheapest way to do this is simply to separate the boxes --
one to the far left, the other to the far right. (Cables aren't exactly
expensive.) This should provide sufficient isolation. If not, you can put
cardboad hoods around the sensors.

Why make something complicated that doesn't need to be complicated?

Cost: longer cables Difficulty: very, very low

I think that I understand somewhat of the question. I have a similar
situation I think. I have two VCR's one on top of the other. I
sometimes will tape one channel while watching another. At times I'll
forget and stop the movie I'm watching. This of course stops and
subsequently ruins the recording I'm trying to make as well. These two
machines are in a tight cabinet and cannot be moved. It would be nice
if somehow the signals could be "coded" so that I could make the
machine doing the recording ignore the remote commands from the
transmitter if I want it to. Lenny

Just put a tag of black vinyl tape over the sensor window on the deck
that's recording.

Sony had three VCR codes, so that Beta, VHS, and 8mm machines could be used
without mutual interference. Of course, you could operate machines of the
same format on different codes.

Check to see whether your VCRs offer multiple codes.

Non-sequitur. The only thing preventing one from being moved is longer
cables.
