76-603: The Apple Remote is a remote control introduced in October 2005 by Apple Inc. for use with a number of its products with infrared capability. It was originally designed to control the Front Row media center program on the iMac G5 and is compatible with many subsequent Macintosh computers. The first three generations of Apple TV used the Apple Remote as their primary control mechanism. It has now been replaced with
152-428: A home theater as many as five or six remotes may be required, including one for cable or satellite receiver, VCR or digital video recorder (DVR/PVR), DVD player , TV and audio amplifier . Several of these remotes may need to be used sequentially for some programs or services to work properly. However, as there are no accepted interface guidelines, the process is increasingly cumbersome. One solution used to reduce
228-413: A light-emitting diode (LED) which is built into the pointing end of the remote control handset. The infrared light pulses form a pattern unique to that button. The receiver in the device recognizes the pattern and causes the device to respond accordingly. Most remote controls for electronic appliances use a near infrared diode to emit a beam of light that reaches the device. A 940 nm wavelength LED
304-467: A software development kit (SDK). foobar2000 supports many audio file formats , has many features for organizing metadata , files, and folders, and has a converter interface for use with command line encoders. To maximize audio fidelity in cases where resampling or downscaling in bit depth is required, it provides noise shaping and dithering . There are a number of official and third-party components which add many additional features. The core
380-404: A beam of light onto one of four photoelectric cells , but the cell did not distinguish between light from the remote and light from other sources. The Flashmatic also had to be pointed very precisely at one of the sensors in order to work. In 1956, Robert Adler developed Zenith Space Command, a wireless remote. It was mechanical and used ultrasound to change the channel and volume. When
456-517: A built-in infrared receiver. For the Apple computers without built-in infrared receiver, there exists a miniature USB receiver (USB-A or USB-C versions), the SmartGUS, which allows to retrofit the infrared functionality to iMac, MacBook and Mac Pro. In this case, all compatible software (iTunes, Keynote, PowerPoint, OpenOffice Impress, QuickTime Player, iPhoto, VLC, Kodi, Remote Buddy, Mira ...) can use
532-595: A built-in rechargeable Lithium Polymer Battery that is charged through a lightning port at the bottom of the remote. In regions where Siri is not supported, the Siri Remote is known as the Apple TV Remote. On September 12, 2017, together with the Apple TV 4K, Apple announced an updated Siri Remote, with a raised white border around the menu button and additional motion input for apps. Earlier models of
608-730: A command. Existing infrared remote controls can be used to control PC applications. Any application that supports shortcut keys can be controlled via infrared remote controls from other home devices (TV, VCR, AC). This is widely used with multimedia applications for PC based home theater systems. For this to work, one needs a device that decodes IR remote control data signals and a PC application that communicates to this device connected to PC. A connection can be made via serial port, USB port or motherboard IrDA connector. Such devices are commercially available but can be homemade using low-cost microcontrollers. LIRC (Linux IR Remote control) and WinLIRC (for Windows) are software packages developed for
684-425: A computer and loaded with updated software code as needed. The CORE unit never made a huge impact on the market. It was much too cumbersome for the average user to program, but it received rave reviews from those who could. These obstacles eventually led to the demise of CL 9, but two of its employees continued the business under the name Celadon. This was one of the first computer-controlled learning remote controls on
760-454: A digital computer: a command from a remote control consists of a short train of pulses of carrier-present and carrier-not-present of varying widths. Different manufacturers of infrared remote controls use different protocols to transmit the infrared commands. The RC-5 protocol that has its origins within Philips, uses, for instance, a total of 14 bits for each button press. The bit pattern
836-399: A distance, usually wirelessly . In consumer electronics , a remote control can be used to operate devices such as a television set , DVD player or other digital home media appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for

The Soviet Red Army used remotely controlled teletanks during the 1930s in the Winter War against Finland and the early stages of World War II . A teletank is controlled by radio from a control tank at a distance of 500 to 1,500 meters, the two constituting a telemechanical group . The Red Army fielded at least two teletank battalions at
988-683: A more complex type of television remote control came in 1973, with the development of the Ceefax teletext service by the BBC . Most commercial remote controls at that time had a limited number of functions, sometimes as few as three: next channel, previous channel, and volume/off. This type of control did not meet the needs of Teletext sets, where pages were identified with three-digit numbers. A remote control that selects Teletext pages would need buttons for each numeral from zero to nine, as well as other control functions, such as switching from text to picture, and
1064-445: A prefix code (0x2e and 0x2f, respectively), followed by the original Play/Pause code (0x02). Older devices ignore the prefix code and thus interpret either button as Play/Pause, while newer devices interpret both codes and use them to determine which button is being pressed. Remote control In electronics , a remote control (also known as a remote or clicker ) is an electronic device used to operate another device from
1140-613: A prototype that inventor Nikola Tesla demonstrated in New York in 1898. In 1903 Spanish engineer Leonardo Torres Quevedo introduced a radio based control system called the " Telekino " at the Paris Academy of Sciences , which he hoped to use to control a dirigible airship of his own design. Unlike previous “on/off” techniques, the Telekino was able to execute a finite but not limited set of different mechanical actions using
1216-412: A single communication channel . From 1904 to 1906 Torres chose to conduct Telekino testings in the form of a three-wheeled land vehicle with an effective range of 20 to 30 meters, and guiding a manned electrically powered boat , which demonstrated a standoff range of 2 kilometers. The first remote-controlled model airplane flew in 1932, and the use of remote control technology for military purposes
1292-493: A submarine. The military also developed several early remote control vehicles. In World War I , the Imperial German Navy employed FL-boats (Fernlenkboote) against coastal shipping. These were driven by internal combustion engines and controlled remotely from a shore station through several miles of wire wound on a spool on the boat. An aircraft was used to signal directions to the shore station. EMBs carried
1368-629: A variety of radio signals transmitted by the remote control device. As a complementary method to infrared remote controls, the radio remote control is used with electric garage door or gate openers, automatic barrier systems, burglar alarms and industrial automation systems. Standards used for RF remotes are: Bluetooth AVRCP , Zigbee (RF4CE), Z-Wave . Most remote controls use their own coding, transmitting from 8 to 100 or more pulses, fixed or Rolling code , using OOK or FSK modulation. Also, transmitters or receivers can be universal , meaning they are able to work with many different codings. In this case,
1444-532: Is closed source , whereas the SDK is licensed under the Three-Clause BSD license . foobar2000 was first released on 20 December 2002 and developed by Peter Pawłowski, who had previously worked at Nullsoft and developed plugins for Winamp . He created foobar2000 with the audiophile community in mind. The software's mascot and logo icon consists of a white "alien cat". foobar2000 supports Windows, though
1520-405: Is infrared (IR) light. The signal between a remote control handset and the device it controls consists of pulses of infrared light, which is invisible to the human eye but can be seen through a digital camera, video camera or phone camera. The transmitter in the remote control handset sends out a stream of pulses of infrared light when the user presses a button on the handset. A transmitter is often
1596-610: Is a freeware audio player for Microsoft Windows , iOS , Android , macOS , and formerly Windows Phone , developed by Peter Pawłowski. It has a modular design , which provides user flexibility in configuration and customization. Standard "skin" elements can be individually augmented or replaced with different dials and buttons, as well as visualizers such as waveform, oscilloscope, spectrum, spectrogram (waterfall), peak and smoothed VU meters, which all of them are analysis-oriented, at least for built-in visualizations. foobar2000 offers third-party user interface modifications through

With addons or plugins, foobar2000 can read the APE , HDCD , AC3 , DTS , SACD and DVD-Audio formats. Other optional features include playback statistics, CD burning , kernel streaming , ASIO support, WASAPI output compatibility, and a UPnP / DLNA renderer, media server and controller for networking. Third-party support
1748-576: Is modulated onto a carrier frequency that, again, can be different for different manufacturers and standards, in the case of RC-5, the carrier is 36 kHz. Other consumer infrared protocols include the various versions of SIRCS used by Sony, the RC-6 from Philips, the Ruwido R-Step, and the NEC TC101 protocol. Since infrared (IR) remote controls use light, they require line of sight to operate
1824-416: Is the internal page table (command page 0x00): This is the command page table (command page 0x0e): To maintain backward compatibility with older devices such as the iPod Hi-Fi, the aluminum Apple Remote does not replace the existing IR code for Play/Pause/Select. Instead, to allow newer devices to distinguish between the separate Select and Play/Pause buttons, it sends two IR codes for each press of those:
1900-449: Is typical. This infrared light is not visible to the human eye but picked up by sensors on the receiving device. Video cameras see the diode as if it produces visible purple light. With a single channel (single-function, one-button) remote control the presence of a carrier signal can be used to trigger a function. For multi-channel (normal multi-function) remote controls more sophisticated procedures are necessary: one consists of modulating
1976-523: The PlayStation 3 and Wii , use Bluetooth . Others, like the Xbox 360 , use proprietary wireless protocols. To be turned on by a wireless remote, the controlled appliance must always be partly on, consuming standby power . Hand- gesture recognition has been researched as an alternative to remote controls for television sets. Foobar2000 foobar2000 (often abbreviated as fb2k or f2k )
2052-575: The Siri Remote in the fourth generation. Prior to the Apple Remote, Apple produced several nameless IR remotes for products such as the Macintosh TV , TV tuner expansion boards, and the PowerCD drive . 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
2128-609: The U.S. Navy . Archibald Low was known as the "father of radio guidance systems" for his pioneering work on guided rockets and planes during the First World War . In 1917, he demonstrated a remote-controlled aircraft to the Royal Flying Corps and in the same year built the first wire-guided rocket. As head of the secret RFC experimental works at Feltham , A. M. Low was the first person to use radio control successfully on an aircraft, an "Aerial Target" . It

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
2280-519: The iPod Hi-Fi or third-party devices tailored to it. Starting with Boot Camp 1.2, the remote has some functionality when a user is running Windows . If iTunes is installed on the Windows partition, pressing the Menu button on the remote will start the program. The remote's media controls also support Windows Media Player , as well as system volume control. Other third-party programs may also utilize
2356-485: The Apple TV. The Siri Remote was launched with the 4th generation Apple TV in 2015. It uses both IR and Bluetooth to communicate with the Apple TV. The remote has a trackpad, dual microphones, five buttons for menu, home, Siri and play/pause, and a volume up/down rocker button. Additionally it has an accelerometer ( IMU ) and a gyroscope which allows the remote to be used as a gaming controller for tvOS apps and games. The remote (unlike previous generations) uses

The first official wireless game controller made by a first party manufacturer was the CX-42 for Atari 2600 . The Philips CD-i 400 series also came with a remote control, the WaveBird was also produced for the GameCube . In the seventh generation of gaming consoles, wireless controllers became standard. Some wireless controllers, such as those of
2584-537: The Moon with the lunar vehicle Lunokhod 1 , the first roving remote-controlled robot to land on another celestial body. Remote control technology is also used in space travel, for instance, the Soviet Lunokhod vehicles were remote-controlled from the ground. Many space exploration rovers can be remotely controlled, though vast distance to a vehicle results in a long time delay between transmission and receipt of

Remote controls are used by insurgents in Iraq and Afghanistan to attack coalition and government troops with roadside improvised explosive devices , and terrorists in Iraq are reported in the media to use modified TV remote controls to detonate bombs. In the winter of 1971, the Soviet Union explored the surface of
2736-420: The battery located behind a compartment in the middle of the device which is accessed by turning a coin in the compartment door's indent. 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
2812-585: The beginning of the Great Patriotic War . There were also remotely controlled cutters and experimental remotely controlled planes in the Red Army. Remote controls in military usage employ jamming and countermeasures against jamming. Jammers are used to disable or sabotage the enemy's use of remote controls. The distances for military remote controls also tend to be much longer, up to intercontinental distance satellite-linked remote controls used by
2888-487: The car for several minutes before they intend to use it, so that the car heater and defrost systems can remove ice and snow from the windows. By the early 2000s, the number of consumer electronic devices in most homes greatly increased, along with the number of remotes to control those devices. According to the Consumer Electronics Association , an average US home has four remotes. To operate
2964-446: The carrier with signals of different frequencies. After the receiver demodulates the received signal, it applies the appropriate frequency filters to separate the respective signals. One can often hear the signals being modulated on the infrared carrier by operating a remote control in very close proximity to an AM radio not tuned to a station. Today, IR remote controls almost always use a pulse width modulated code, encoded and decoded by

3192-489: The difficulty involved in playing the game while keeping the infrared transmitter pointed at the console. Early wireless controllers were cumbersome and when powered on alkaline batteries, lasted only a few hours before they needed replacement. Some wireless controllers were produced by third parties, in most cases using a radio link instead of infrared. Even these were very inconsistent, and in some cases, had transmission delays, making them virtually useless. Some examples include
3268-691: The encoder type used: fixed code and rolling code . If you find dip-switches in the remote, it is likely to be fixed code, an older technology which was widely used. However, fixed codes have been criticized for their (lack of) security, thus rolling code has been more and more widely used in later installations. Remotely operated torpedoes were demonstrated in the late 19th century in the form of several types of remotely controlled torpedoes . The early 1870s saw remotely controlled torpedoes by John Ericsson ( pneumatic ), John Louis Lay (electric wire guided), and Victor von Scheliha (electric wire guided). The Brennan torpedo , invented by Louis Brennan in 1877
3344-517: The features of the Apple Remote, the same as with the legacy built-in infrared receiver. It is currently unknown whether the Apple Remote can be used with a USB receiver on Apple Silicon -based Macs or not, which includes the newly introduced Mac Studio . 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
3420-514: The first wireless remote control for a consumer electronics device. Using pulse-count modulation, this also was the first digital wireless remote control. One of the first remote intended to control a television was developed by Zenith Radio Corporation in 1950. The remote, called Lazy Bones, was connected to the television by a wire. A wireless remote control, the Flash-Matic , was developed in 1955 by Eugene Polley . It worked by shining
3496-434: The iMac with polycarbonate enclosures featured a magnetic rest for the remote, which was later removed. Using the Apple Remote with newer MacBook Air, Retina MacBook, or other Mac models 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
3572-421: The market. In the 1990s, cars were increasingly sold with electronic remote control door locks. These remotes transmit a signal to the car which locks or unlocks the door locks or unlocks the trunk. An aftermarket device sold in some countries is the remote starter. This enables a car owner to remotely start their car. This feature is most associated with countries with winter climates, where users may wish to run
3648-451: The navigation ring was flush with the curvature of the remote's aluminum body. In the later revision, the ring is slightly raised to make it easier to locate the ring by touch. Replacement of the CR2032 battery in the original remote is done with a small pointed object such as a paper clip at the bottom right edge of the device, where the battery slides out on a tray. The newer version has
3724-431: The normal television controls of volume, channel, brightness, color intensity, etc. Early Teletext sets used wired remote controls to select pages, but the continuous use of the remote control required for Teletext quickly indicated the need for a wireless device. So BBC engineers began talks with one or two television manufacturers, which led to early prototypes in around 1977–1978 that could control many more functions. ITT
3800-427: The number of remotes that have to be used is the universal remote , a remote control that is programmed with the operation codes for most major brands of TVs, DVD players, etc. In the early 2010s, many smartphone manufacturers began incorporating infrared emitters into their devices, thereby enabling their use as universal remotes via an included or downloadable app . The main technology used in home remote controls
3876-485: The one in a radio receiver. The superheterodyne receiver is used because of its stability, high sensitivity and it has relatively good anti-interference ability, a small package and lower price. A remote control is used for controlling substations, pump storage power stations and HVDC -plants. For these systems often PLC-systems working in the longwave range are used. A subset of Power-Line communication that sends remote control signals over energized AC power lines. This

#17327728598573952-511: The problem. The Apple Remote uses a modified NEC IR protocol 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: 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. This

Remote controls are used in photography, in particular to take long-exposure shots. Many action cameras such as the GoPros as well as standard DSLRs including Sony's Alpha series incorporate Wi-Fi based remote control systems. These can often be accessed and even controlled via cell-phones and other mobile devices. Video game consoles had not used wireless controllers until recently, mainly because of
4104-420: The rapid decrease in price of transistors made possible cheaper electronic remotes that contained a piezoelectric crystal that was fed by an oscillating electric current at a frequency near or above the upper threshold of human hearing , though still audible to dogs . The receiver contained a microphone attached to a circuit that was tuned to the same frequency. Some problems with this method were that
4180-417: The rear side to facilitate typing, and be usable as a pointing device. Wired and wireless remote control was developed in the latter half of the 19th century to meet the need to control unmanned vehicles (for the most part military torpedoes). These included a wired version by German engineer Werner von Siemens in 1870, and radio controlled ones by British engineer Ernest Wilson and C. J. Evans (1897) and
4256-457: The receiver could be triggered accidentally by naturally occurring noises or deliberately by metal against glass, for example, and some people could hear the lower ultrasonic harmonics. In 1970, RCA introduced an all-electronic remote control that uses digital signals and metal–oxide–semiconductor field-effect transistor (MOSFET) memory . This was widely adopted for color television , replacing motor-driven tuning controls. The impetus for
4332-409: The remote can include putting a device into sleep mode , selecting a partition to boot from on startup, and ejecting optical discs. A device can be configured to respond only to a particular remote. An iPod placed in a dock featuring an IR sensor can be used with the remote for music and media control. The iPod's menus cannot be operated with the remote. The Apple Remote can also be used to control
4408-429: The remote part, which has an IR transmitter mimicking the original IR control. Infrared receivers also tend to have a more or less limited operating angle, which mainly depends on the optical characteristics of the phototransistor . However, it is easy to increase the operating angle using a matte transparent object in front of the receiver. Radio remote control (RF remote control) is used to control distant objects using

Most functionality also works as intended under Wine on Linux , although the program's crash reporter will detect Wine and direct
4788-480: The transmitter is normally called a universal remote control duplicator because it is able to copy existing remote controls, while the receiver is called a universal receiver because it works with almost any remote control in the market. A radio remote control system commonly has two parts: transmit and receive. The transmitter part is divided into two parts, the RF remote control and the transmitter module. This allows
4864-448: The transmitter module to be used as a component in a larger application. The transmitter module is small, but users must have detailed knowledge to use it; combined with the RF remote control it is much simpler to use. The receiver is generally one of two types: a super-regenerative receiver or a superheterodyne . The super-regenerative receiver works like that of an intermittent oscillation detection circuit. The superheterodyne works like
4940-403: The user pushed a button on the remote control, it struck a bar and clicked, hence they were commonly called "clickers", and the mechanics were similar to a pluck . Each of the four bars emitted a different fundamental frequency with ultrasonic harmonics, and circuits in the television detected these sounds and interpreted them as channel-up, channel-down, sound-on/off, and power-on/off.

In May 2016, versions for mobile devices were released, and in January 2018, an early beta version for macOS
5092-743: The user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside. Early television remote controls (1956–1977) used ultrasonic tones. Present-day remote controls are commonly consumer infrared devices which send digitally-coded pulses of infrared radiation. They control functions such as power, volume, channels, playback, track change, energy, fan speed, and various other features. Remote controls for these devices are usually small wireless handheld objects with an array of buttons. They are used to adjust various settings such as television channel , track number, and volume . The remote control code, and thus

The Blab-off was a wired remote control created in 1952 that turned a TV's (television) sound on or off so that viewers could avoid hearing commercials. In the 1980s Steve Wozniak of Apple started a company named CL 9 . The purpose of this company
5624-425: Was to create a remote control that could operate multiple electronic devices. The CORE unit (Controller Of Remote Equipment) was introduced in the fall of 1987. The advantage to this remote controller was that it could "learn" remote signals from different devices. It had the ability to perform specific or multiple functions at various times with its built-in clock. It was the first remote control that could be linked to
