A menu system for a video teleconferencing system is provided. The menu system is arranged as a hierarchical series of levels (302, 306). At the highest level (302), the menu system includes one or more first level menus (304a-304e). Each first level menu is activated by a respective button on a remote control (216) or other control device. Each first level menu (300) includes a series of options. Each option (304a-304e) has an associated second level menu (306) that is displayed when the option is highlighted (304a). A second level menu (306) may be activated by highlighting its associated first level option (304a) and then pressing a predetermined button on the remote control (112). Once the level menu is activated, the user may select from a series of second level options (400) included in the second level menu. Each second level option (400a-400e) activates an associated selection dialog. The menu system is configured so that all active levels of the hierarchy are displayed at all times. Thus, an active selection dialog would be shown along with its associated active second level menu and its associated first level menu. This orients the user and simplifies navigation. All active options are also maintained in a highlighted state. This reinforces the users ability to determine his or her current location within the menu hierarchy. |
