I'm currently considering buying this http://tinyurl.com/7go42 LG lcd TV. One of its features is an IR in connection via a 3.5mm jack. I was planning on feeding it RGB via a kat5 pair.

My question is which direction does the IR transmission over kat5 operate? i.e is it in the same direction as the video or opposite? my requirement would be for it to be in the same direction as my entire system is contolled by girder via firm from node 0. On that note, should this be possible, can the output of a firm splitter box be fed directly into a kat5 box then from the receiving kat5 box directly into the TV or will some further widgetry be required?

Thanks

James
