1 Scope
®
The present document is part of the MirrorLink specification which specifies an interface for enabling remote user
interaction of a mobile device via another device. The present document is written having a vehicle head-unit to interact
with the mobile device in mind, but it will similarly apply for other devices, which provide a color display, audio
input/output and user input mechanisms.
Current MirrorLink solutions are concentrated on utilization of MirrorLink Client's main display to mirror applications
or provide variety services on the MirrorLink Server. However, there are so many MirrorLink Clients which have
several other displays, such as cluster display panel, Heads-up Display (HUD) and so on. Instead of applications
mirroring, using these displays, the driver and the passenger can be provided with a variety meta information such as
turn by turn information, photo or graphic information, meta data information of audio and video clip, text information,
etc. Those Meta Information Data Services are based on the SBP (Service Binary Protocol) framework.
The present document specifies navigation meta data service based on SBP (Service Binary Protocol) framework. By
receiving this data, the MirrorLink Client (e.g. a car) can provide navigation information to driver and passenger
e.g. through the car's cluster display panel, or heads-up display.
