If the tuner does not have a jack for an external IR receiver, the simplest
solution is an IR extender like X-10's Powermids.

Given that you had to ask, my guess is that adding an external IR receiver
to the tuner is a little beyond your skillset but if the tuner uses an IR
receiver module, in most cases, you can add another receiver in parallel.
The trick is in determining whether it uses an IR receiver (rather than a
phototransistor or PIN diode) and then determining the receiver's pinout.

If you look at the datasheet for IR receiver modules, nearly all have an
internal pull-up on the data-out line and are active low. Here's an example.
