An Internet protocol television (IPTV) system is driven by a graphical user interface (GUI) controlled by an input device attached to an Internet access device that in turn connects to the GUI over IPTV connections. The input device may be a keyboard, smart phone, iPad, mouse, personal computer, laptop, touch screen, or other generic universal serial bus (USB), IEEE 1394 (FireWire), or other connected device. Connection between the input device and the GUI may be either wired (including, but not limited to USB, IEEE 1394, and Ethernet) or wireless (including, without limitation, infrared (IR), radio frequency, or other form of electromagnetic transmission). Regardless of connection method, the input device acts to operate and command the IPTV GUI so as to navigate and control the IPTV. By appropriate GUI implementations, a single input device may be configured to operate one or more windows on one or more display via IPTV connections. |
