A unified navigation system for television and non-television services wherein operations of the non-television services are mapped to similar operations of the television service in order to provide a familiar interface to the user. In one embodiment, television channels and other, non-television services are displayed to the user as rows (70, 76, 77, 78, 79, 80, 81) of an electronic program guide (65). User input is provided through a remote control (63) having directional keys for moving a cursor to highlight (71) a selected item in the electronic program guide and one or more keys for activating the selected service. The user can thereby easily select any of the available services. The system can be configured to register newly available services and map their operations to the existing navigation controls. The system can be configured by a service provider or by the user and may incorporate user preferences and access controls. |
