While the Apple TV comes with its own elegant remote, you must use yet another remote in order to switch your TV's input to the Apple TV and to adjust volume. Alternatively, you could replace the Apple Remote, as well as all your other remotes, with a single controller like the Logitech Harmony 650 $70.
sends a sequence of commands that:
- switches the TV input to the Apple TV;
- configures the Harmony's Menu, Select, Play keys to match those of the Apple TV's Remote; and
- configures the Harmony's volume buttons to control the volume of your TV or your audio system.
An added bonus of replacing the Apple Remote with the Harmony 650 is that the 2 AA's that power the Harmony allow for further reach of the IR signal, which may be useful in some situations. For example, my Apple TV 2 is mounted out of sight, attached with velcro, vertically on the back of my TV. Despite the lack of line-of-sight, the Harmony 650's signal has no difficulty reaching the Apple TV.
