IR REMOTES
To control a device, the IR remote needs to be pointed directly at it. There must not be any obstruction between these remotes and the devices they control in order for them to function properly. The range of an IR remote is about 30 feet and it is currently more common than an RF remote – a fact attributed mostly to its cost.
When you only watch TV in one room, you may want to use an infrared remote control.

RF REMOTES
The signal is strong enough to pass through walls and floors so that you can use RF remotes even if you are in another room from the device being controlled. Wireless remotes typically have an operating range of 100 feet. The majority of electronic devices do not come equipped with RF functionality. It is possible in most cases to add RF systems with an extender. It will convert the RF signal you send to an IR signal so that your devices will “understand” and respond to it.
You can control multiple devices (such as video, DVD, audio, and lighting) with just one remote control thanks to the capabilities of RF.
RF may be your best choice if you have multiple devices in your home theater room or if there are a variety of entertainment devices scattered throughout your home. The RF remote is more expensive than the IR remote, but it offers greater convenience.
