Extensibility Buttons - Optional
This section describes the extensibility control buttons, which are optional. The standard
Windows Media Center IR protocol provides for 12 extensibility buttons. These buttons map to
EXT0 through EXT11 in the Windows Media Center human interface design (HID) collection. The
IR stack is programmed to pass these buttons through as HID usage as defined later. For
example, an extensible button could be used to teach the user how to program a button on the
remote control in Windows Media Center, start a program, or control home automation.
