Applications for extending IR receiver

Moving a MythTV (or any media center machine for that matter) to a location other than that of the display can often be the most affordable solution to a stubborn problem. Noise. Often times, space constraints or aestetics may prevent a machine from residing near the display. Some power-users often centralize their equipment to a machine room in the basement such as this fellow has.

Ultimately, if the machine that needs to be controlled is not within line-of-sight of the remote control or outside of it's nominal range, an IR receiver mounted in the viewing room can be wired to the remotely installed frontend. A classic example is the common practice of moving the machine to a cupboard or room under the stairs to because space isn't available in a small apartment.

Another popular practice with the advent of the wall mounted flat-panel display is to hide all of the existing home theatre equipment in a nearby closet or built into a rack enclosure behind a panel thus creating a streamlined or minimalist decor. In this scenario, each piece of equipmemnt would also need to have it's respective IR signal forwarded or "repeated". An IR control system would be used to collect, concentrate and then deliver the signals from any remote control to the proper piece of equipment (eg. HT receiver, sat/cable box, DVD).
