  • Method of outputting screens from server and client devices in performing mirrorlink
    Patent number: 10623549
    Abstract: A MirrorLink server for communicating with a MirrorLink client, the MirrorLink server including a display unit; a memory configured to store at least one of a certified application; a communication unit configured to establish a connection between the MirrorLink client and the MirrorLink server; and a controller coupled to the display unit, the memory and the communication unit. The controller is further configured to provide the at least one of a certified application stored in the memory, receive at least one of an interrupt, wherein the at least one of the interrupt corresponds to a home key event or a back key event, and switch either to the MirrorLink client's native UI or another screen in response to the at least one of the interrupt.
