Pushing a graphical user interface to a remote device with display rules provided by the remote device

摘要

A graphical user interface (“GUI”) can be presented on a remote control accessory device that has user input and display devices. The portable media device can provide the accessory with a GUI image to be displayed. The accessory can specify the configuration of the remote GUI image and send that information to the portable media device. The portable media device can generate a GUI image based on the configuration and send the GUI image to the accessory. The accessory can display the GUI image on one part of its display and other information on another part of its display. The portable media device can define different GUI image types for use with different types of input controls of the accessory. Based on which input control is currently active, the portable media device can send the corresponding GUI image to the accessory for display on the accessory display.
