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 colour display, audio input/output and user input mechanisms.

The contents of the MirrorLink Server device's screen are transferred to the MirrorLink Client device. The control inputs are transferred from the MirrorLink Client to the MirrorLink Server. Screen copy methods can be used to copy the content of the MirrorLink Server's framebuffer to the MirrorLink Client's display. The copy operation can include rotation or colour conversion. The frame buffer is used as an abstraction layer, allowing any changes to the applications and services running on the mobile device to be avoided. For this purpose, the Virtual Networking Computing (VNC) protocol is used.
