Abstract: A sink device in a Wireless Display (WD) system may establish a user input device control communication channel between a source device and sink device in a WD system to allow the sink device to send device control inputs to the source device. The user input device control communication channel may include a reverse channel architecture referred to as the Wi-Fi User Input Back Channel (UIBC) that has been modified to transport one or more additional input types over UDP. For example, UIBC may be extended to transport voice input and VNC input types.
