In one embodiment, a programmable multimedia controller controls electronic devices, including display devices. A remote control communicates with the programmable multimedia controller. An on screen display is displayed on a selected one of the display devices. The on screen display enables the selected one of the display devices to function as a virtual telephone that is user-operable to initiate outgoing telephone calls and to answer incoming telephone calls. When an outgoing telephone call or incoming telephone call is in progress, the on screen display shows text or graphics related to the outgoing telephone call or the incoming telephone call. The on screen display is overlaid on another video signal which is already being displayed on the selected one of the display devices.
