An infrared repeater, also known as an IR blaster, is a device that allows an infrared remote to control a tertiary device. Some models simply extend a remote's function with its own companion device, allowing it to be used across long distances or through walls. The set-up of these devices is easy; configuring the primary devices (DVRs or computer-based TV tuners) is usually much more involved. The set-up process will vary depending upon what device you're using the IR blaster with.
