That's not exactly what it is. What it is, is an "IR blaster", and can be used to control a satellite box, when configured appropriately. Usually, you tape the IR emitter (most of which have a 'passthrough' ability) to the front of your satellite box's input, so it can send the signal to it. For example, you are using your remote to control your PC, and you bring up your PVR software. You tell it you want to record "The Big Bang Theory" which is on channel 250 at 9:30 p.m. It records this in the PVR software's database, and at 9:30, it sends a signal through the IR emitter to wake the satellite, change to channel 250, and start recording.
It's a handy little item, with the right software and configuration.
