A method of controlling a docking station, the docking station comprising a wireless access point having a network address for communicating with a mobile device over a local area wireless network connection, a display controller having an Internet Protocol, IP, or Media Access Control, MAC, network address, the display controller being configured to process at least video data for output to at least one display device over a display-specific connection, and a Universal Serial Bus, USB, controller configured to process at least USB data signals for output to one or more peripheral devices over a USB connection, the method comprising: communicating by the access point with a mobile device over the local area wireless network to establish a local area wireless network connection with the mobile device; communicating by the access point with the mobile device to establish a USB connection tunnelled over the local area wireless network connection with the mobile device; receiving, by the access point over the USB connection from the mobile device, a request for the network address of the display controller; transmitting, by the access point in response to the request, the IP or MAC network address of the display controller to the mobile device over the USB connection, thereby allowing the mobile device to transmit at least video data over the local area wireless network connection addressed to the display controller using the IP or MAC network address of the display controller without using the USB connection; receiving (S35B), on the USB connection at the access point, at least USB data signals from the mobile device and switching (S36B) the at least USB data signals to the USB controller for processing and output to one or more peripheral devices connected to the docking station; receiving (S35A), on the local area wireless network connection at the access point, the at least video data addressed to the IP or MAC network address of the display controller and switching (S36A) the at least video data addressed to the IP or MAC network address of the display controller directly to the display controller without passing via the USB controller. communicating by the access point with a mobile device over the local area wireless network to establish a local area wireless network connection with the mobile device; communicating by the access point with the mobile device to establish a USB connection tunnelled over the local area wireless network connection with the mobile device; receiving, by the access point over the USB connection from the mobile device, a request for the network address of the display controller; transmitting, by the access point in response to the request, the IP or MAC network address of the display controller to the mobile device over the USB connection, thereby allowing the mobile device to transmit at least video data over the local area wireless network connection addressed to the display controller using the IP or MAC network address of the display controller without using the USB connection; receiving (S35B), on the USB connection at the access point, at least USB data signals from the mobile device and switching (S36B) the at least USB data signals to the USB controller for processing and output to one or more peripheral devices connected to the docking station; receiving (S35A), on the local area wireless network connection at the access point, the at least video data addressed to the IP or MAC network address of the display controller and switching (S36A) the at least video data addressed to the IP or MAC network address of the display controller directly to the display controller without passing via the USB controller.
