MirrorLink is a device interoperability standard that offers integration between a smartphone and a car's infotainment system. MirrorLink transforms smartphones into automotive application platforms where apps are hosted and run on the smartphone while drivers and passengers interact with them through the steering wheel controls, dashboard buttons and touch screens of their car's In-Vehicle Infotainment (IVI) system. MirrorLink utilizes a set of well-established, non-proprietary technologies such as IP, USB, Wi-Fi, Bluetooth, Real-Time Protocol (RTP, for audio) and Universal Plug and Play (UPnP). In addition, MirrorLink uses Virtual Network Computing (VNC) as the baseline protocol to display the user interface of the smartphone applications on the infotainment system screens and to communicate user input back to the mobile device. ==Beginnings== MirrorLink started out as a research project. Researcher Jörg Brakensiek, from Nokia Research Center in Palo Alto, US, took results from the noBounds! project—invented by researcher Bernd Steinke from the Nokia Research Center in Bochum, Germany—and applied them to the automotive domain. The initial approach〔(【引用サイトリンク】title=The noBounds Project at Internet Tablet Talk )〕 applied by Bernd Steinke contained three specialised sub-protocols for optimal power efficiency: 2D, 3D and Media. Support for 2D graphics composition via X11 mirroring was only needed by the requirements of the chosen source device, a Nokia N800 mobile Linux device, and the desire to speed up demo availability to show mirroring use cases. OpenGL ES was used for fast 3D graphics and alpha based Porter-Duff compositing for shine-through 2D effects. To make this future relevant approach available on the limited N800 Mesa 3D was used〔(【引用サイトリンク】title=noBounds! - blast Smartphones display bounds! on Vimeo )〕 for local playback. High Definition Media streaming was implemented via OpenMAX, RTP and a timed sideband control to allow synchronous displayed streaming〔(【引用サイトリンク】title=noBounds! - blast Smartphones display bounds! - YouTube @ 52sec )〕 of the original video file without transcoding. The Initial implementations have remoted the GUI, Games and media content of an Nokia N800 and later an N810 mobile Linux device. This demonstration of, at that time, not expected capabilities of mobile devices, was widely reported. In parallel, a member of a CE4A company, who had seen the same initial results, contacted Nokia and the collaboration between Nokia and CE4A started. First ideas have been published and demonstrated using a Nokia N810 Internet tablet at IEEE CCNC 2009 conference. Together with two other researchers, Raja Bose and Keun-Young Park, from Nokia Research Center in Palo Alto, and in close collaboration with the Consumer Electronics for Automotive (CE4A) group of German car manufacturer, the original Terminal Mode concept has been created. The name Terminal Mode originated from the name of the Expert Group within the CE4A, which created a Positioning Paper.〔(【引用サイトリンク】title=Positioning Paper EG Terminal Mode, Functional Mobile Device Integration, version 0.6, CE4A )〕 Nokia, together with Magneti Marelli, publically demonstrated a first Terminal Mode concept, during a Navteq Connection event, in conjunction with the Frankfurt International Auto Show (IAA) in September 2009. A first car integration was shown at Geneva Auto Show in March 2010, using a Nokia N97 prototype implementation of Terminal Mode, integrated into a Valmet concept car.〔(【引用サイトリンク】title=Nokia’s Terminal Mode spotted in the wilds of the Geneva Motor Show )〕 A draft 0.9 specification version〔(【引用サイトリンク】title=Terminal Mode Architecture )〕 was released in March 2010.〔(【引用サイトリンク】title=NRC Developed "Terminal Mode" Announced )〕 In July 2010 the Terminal Mode was presented, integrated to a VW Passat at MobileBeat 2010.〔(【引用サイトリンク】title=VW Passat takes the red pill, jacks into Nokia’s Terminal Mode )〕 A first real live demonstration can be seen in from September 2010, shortly before the Terminal Mode specification became public in 6 October 2010.〔(【引用サイトリンク】title=Terminal Mode Functional Mobile Device Integration )〕 Early adopters included Continental,〔(【引用サイトリンク】title=Nokia and Continental Automotive want you to drive, Tweet and talk )〕 Alpine,〔(【引用サイトリンク】title=Alpine Electronics Announces Strategic Partnership with Nokia and NAVTEQ to Integrate Smartphones Into Car Infotainment Systems )〕 and Clarion.〔(【引用サイトリンク】title=Clarion joins Nokia’s Terminal Mode collaboration, as Audi unveils a new Connectivity Navigation Radio platform )〕 The collaboration between Nokia and CE4A on Terminal Mode led to the formation of the Car Connectivity Consortium. The Car Connectivity Consortium brought together major players in the automotive and mobile device industries including a large number of Tier-I suppliers and even a few network providers. On 12 September 2011, Terminal Mode was renamed as MirrorLink and became a commercial trademark owned by the Car Connectivity Consortium. As of May 2012, the Car Connectivity Consortium had 56 members, and included almost all major automobile and mobile device manufacturers in the world. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「MirrorLink」の詳細全文を読む スポンサード リンク
