Abstract

In one embodiment, a method of operating a communications system is disclosed comprising receiving a request for establishment of a session from a terminal, establishing the session with the terminal, and providing at least one navigation video segment to the terminal, via the session. The communications system may be a source of programming, such as a cable system, and the terminal may be a set-top terminal coupled to a display device. The navigation video segment may be used by the terminal to create selection menus to be displayed for user navigation. The video segments may be rich media video segments. A playlist may be generated comprising an indexed listing of a plurality of available video segments. The playlist may facilitate retrieval of video segments requested by a terminal. Communications systems, terminals and methods of operating a terminal are disclosed, as well.
