IR signal from your Blu-ray / DVR / et al. remotes through its CEC channel, and then transmitting it directly into your hardware's sensor, thereby extending your IR range without an extra cable. The kit also has a switch for those times when you actually need to use the CEC channel. The InjectIR is up now for pre-order on Sewell's site. It'll start shipping next month and will run you $45 -- a small price to pay for being able to move the sofa back where it belongs.
