The Apple Remote is a remote control device released in or after October 2005 by Apple Inc. for use with a number of its products which use infrared capabilities. The device was originally designed to interact with the Front Row media program on the iSight iMac G5 and is compatible with some later desktop and portable Macintosh computers. Apple TV ships with and uses the Apple Remote as its primary control mechanism.

Design[edit]

Original Apple Remote

The original Apple Remote was designed with six buttons and made of white plastic. Its shape and layout resembled the first-generation iPod Shuffle. A circular Play/Pause/Select button sat in the center of a larger four-button circle of (clockwise): Volume Up, Next/Fast-forward, Volume Down and Previous/Rewind. A separate Menu button was positioned below. The price was set at US$29.00.[1]

In October 2009, the remote was redesigned as a thinner and longer aluminum version. The new remote was released along with the 27 inch aluminum iMacs and multi-touch Magic Mouse. The Play/Pause button was moved out of the center of the directional buttons and put beside the Menu button (under the directional buttons). The symbols for the Volume Up/Down and Next/Fast-forward buttons were replaced with small dots, to make it clear that the buttons were also used to move up, down, left, and right within menus. All of the buttons became black and embossed within aluminum. Along with the new design, the price was dropped to US$19.99. The newer design also underwent a slight revision with the navigation ring. In a small percentage of older remotes, this ring was flush with the curvature of the remote's aluminum body. The more-common revision is bulged slightly; presumably so users can find the ring more easily by touch.

The original remote's battery is accessed by pushing a small, blunt object, such as a paper clip or a 3.5 mm headphone plug, into a tiny indent at the bottom right edge of the remote, revealing the compartment which houses the CR2032 lithium 3.0 V button cell. For the newer remote, a coin can be used to access the battery on the back of the remote[2]

Functions[edit]

The Apple Remote's original function was to enable navigation in Front Row, which allows users to browse and play music, view videos (DVDs and downloaded files) and browse photos. Although Front Row was removed from OS X 10.7 and later, some Apple software still works with the remote. It can still be used to control presentations in Apple Keynote (on both Intel Macs & PowerPC Macs), picture slide shows in iPhoto and Aperture, DVD films via DVD Player, and to play video and audio in iTunes and QuickTime. Other software that is still compatible includes Elgato's EyeTV 3.5, and VLC media player. The remote can also be used to run presentations in Microsoft PowerPoint 2008 or in OpenOffice.org Impress.

Other functions controlled by the remote can include putting a device into sleep mode, selecting a partition to boot from on startup, and ejecting optical disks.[3] A device can be configured to respond only to a particular remote.[4]

iPods[edit]

An iPod placed in a dock featuring an IR sensor can be used with the remote for music and media control.[5] The remote's menu functionality does not work on the iPod. The Apple Remote can also be used to control the iPod Hi-Fi or third party devices tailored to it.[6]

Boot Camp[edit]

Starting with Boot Camp 1.2, the remote has had some functionality when a user is running Windows. If iTunes is installed on the Windows partition, pressing the Menu button on the remote will load the program. The remote's media controls also support Windows Media Player, as well as system volume control.[7] Other third party programs may also utilize the remote's capabilities; media applications such a foobar2000 and Media Player Classic allow users to control their functions via the remote. Applications must be in focus for the remote to control them. Boot Camp 5, the latest version of the software, also includes drivers for the remote control.[8]

iOS App[edit]

Main article: iTunes Remote

Apple offers a free 'Remote' app for iOS devices (available in the iTunes App Store) which allows for wireless control of iTunes on Mac/Windows computers or the Apple TV.

Compatibility[edit]

Model Compatibility
MacBook Original - Mid 2009 (Except White Unibody)
MacBook Air Original - Mid 2009
MacBook Pro Original - Mid 2012 (Except Retina)

Earlier models of the iMac (Polycarbonate iMac) featured a magnetic rest for the remote,[10] which was later removed.

Use with new MacBook Airs, Retina MacBook Pros and older Macs[edit]

Using the Apple Remote with new MacBook Airs, Retina MacBooks or old Macs without a built-in IR Receiver requires a USB-based infrared receiver and additional software from a third party.

Using Remote Buddy (from IOSPIRIT GmbH) or mira (from Twisted Melon), it is possible to connect an external USB receiver such as the Windows Media Center Edition eHome receiver, and use the Apple Remote on these machines with full support for sleep, pairing, low battery detection and controlling a variety of Apple and third party software. In addition, Remote Buddy is able to emulate events of an Apple Remote on these systems, enabling users to use software written for the Apple Remote in exactly the same way as with Macs that have a built-in infrared receiver.

Infrared interference[edit]

Because many electrical appliances use infrared remote (IR) controls, concurrent use of the Apple Remote with other IR remotes may scramble communications and generate interference, preventing stable use. Remotes should be used individually to circumvent the problem.[11]

Technical details[edit]

Apple Remote 2nd generation with lit infrared LED.

The Apple Remote uses an NEC IR protocol[1] which consists of a differential PPM encoding on a 1:3 duty cycle 38 kHz 950 nm infrared carrier. There are 32 bits of encoded data between the AGC leader and the stop bit:[12]

Protocol on (µs) off (µs) total (µs)
leader 9000 4500 13500
0 bit 560 560 1120
1 bit 560 1690 2250
stop 560 N/A 560

While the Apple Remote uses the NEC IR protocol for the timing, the 32-bit data package is in a different format. It consists of two 16 bit LSB words.

Bits Type Comment
11 Vendor This is always 0x43f and can be used to identify an Apple Remote
5 Command Page 0x0 for the pairing and other commands, 0xe for the different buttons
8 Device ID A unique device ID, used to allow pairing of a remote to a specific device. It can be changed with the pairing command
7 Command Actual command for the Command Page
1 Odd parity All 32 bits added together have to equal 1

This is the internal page table (command page 0x00):

Value Command Description
0x01 Pairing Menu + Select for 5s (pair & increment the Device ID) or Menu + Next for 5s (just pair)
0x02 Factory Defaults Menu + Previous for 5s
0x03 Low Battery Old (white) Apple Remote
0x07 Low Battery New Apple Remote

This is the command page table (command page 0x0e):

Value Button Command
0x01 Menu Menu
0x02 Center In the old remote this is the Play/Pause and Select button
0x03 Right Next/Fast-Forward
0x04 Left Previous/Rewind
