MirrorLink
MirrorLink (in English: "mirror connection") refers to a data transmission standard for a connection between a mobile device, e.g. B. a smartphone , and the computer built into an automobile, which is responsible for navigation and media playback (English: "infotainment" as a case word from "information", ie information, and "entertainment", ie entertainment). Certain application programs (“apps”) are executed on the mobile device, while the driver or occupants can control them using controls built into the car (e.g. buttons or switches on the steering wheel or a touch-sensitive screen).
MirrorLink uses a number of best practices and protocols including IP , USB , Wi-Fi , Bluetooth , RTP (for audio playback) and UPnP . In addition, MirrorLink uses Virtual Network Computing (VNC) as the main protocol to transmit the user interface of the smartphone app to the screen or screens of the car and to transmit user inputs and commands to the smartphone in the return channel.
Emergence
The development of MirrorLink began with a research project: Jörg Brakensiek from the Nokia Research Center in Palo Alto used the results of the "noBounds!" Project pursued by the Nokia development laboratory in Bochum and used them for the automotive sector.
The original approach by Bernd Steinke, a researcher at Nokia, envisaged three sub-protocols, each optimized for low power consumption: 2D, 3D and media playback. The requirement to support 2D graphics via X11 resulted from the choice of the test device, a Linux-based Nokia N800 , and the desire to be able to demonstrate the mirroring of the screen content as soon as possible. OpenGL ES was used for 3D playback and the Porter-Duff process for transparency effects. Due to the nature of the N800, Mesa 3D was used for local playback of media, and OpenMAX , RTP and a time-controlled secondary channel were used for transmission ("streaming") without transcoding . As a result of the project, the user interface could be transferred to another device, movies could be played, and even games could use the remote screen. Demonstrations of these skills, which at the time were not believed to be mobile devices, attracted widespread attention.
At that time there was the Consumer Electronics for Automotive (CE4A) working group for German automobile manufacturers. An employee of this CE4A who had seen the demonstrations contacted Nokia and a collaboration began. A Nokia N810 Internet Tablet was used at the IEEE CCNC 2009 conference to publish the first ideas and for demonstration purposes. Together with two other researchers, Raja Bose and Keun-Young Park, both from the Nokia Research Center in Palo Alto, the so-called “terminal mode concept” was developed.
At a Navteq event as part of the Frankfurt International Motor Show (IAA) in September 2009, Nokia and Magneti Marelli demonstrated an initial implementation of this concept. At the Geneva Motor Show in March 2010, a prototype solution that was integrated into a car was demonstrated. A Nokia N97 was coupled with a Valmet test car. A preliminary version 0.9 of the associated protocol specification was published in March 2010 and the integration into a VW Passat was shown in July at MobileBeat 2010. A demonstration under real conditions took place in September just before the first official specification of the "Terminal Mode" was adopted on October 6, 2010. The first users were Continental (Hanover), Alpine and Clarion.
The “Car Connectivity Consortium” emerged from the collaboration between Nokia and CE4A in the specification of the “Terminal Mode” (roughly in German: “Working group for the connection of car electronics with other devices”). The consortium brought together major players in the automotive industry and mobile device manufacturers, as well as a number of automotive suppliers and even some manufacturers of network components. On September 12, 2011, “Terminal Mode” was officially renamed “MirrorLink”, and this term became a registered trademark of the “Car Connectivity Consortium”. As of May 2010, the consortium had 56 members, including almost all major automobile and mobile device manufacturers around the world.
At the beginning of 2016, Škoda and its development partners presented Wireless MirrorLink . The wireless connection between the telephone and the Škoda infotainment system was developed by Škoda together with its partners TechniSat and RealVNC. With Wireless MirrorLink , the data is transferred via WLAN and not via USB cable.
distribution
MirrorLink currently works with a wide variety of HTC mobile devices, three LG mobile devices, Samsung Galaxy mobile devices and old Sony Xperia Z devices (all with Android). In 2012, Sony, Pioneer and Alpine released car radios that support MirrorLink. Phone manufacturer Motorola announced support for MirrorLink in 2012. Due to the takeover of Motorola by the company Google, which is not a member of the CCC, the announcement remained. After a long membership in the CCC, Huawei only released its first mobile device with MirrorLink support in 2017. A large number of automobile manufacturers (some with just a few models) now support MirrorLink. These include Buick, Chevrolet, Citroën, Honda, Hyundai, KIA, Peugeot, SEAT, Škoda, Smart, Suzuki, Toyota and Volkswagen.
