A method and apparatus for providing an interactive menu structure within an interactive information distribution system. The menu structure is embodied in a combination of software, which provides a so-called navigator and a set top terminal that provides certain functionality for the navigator and a video session manager which provides support functionality for the set top terminal. The menu structure has each menu (e.g., menu instructions, graphics and video) contained in downloadable applets which are sent upon request from the service provider equipment to the set top terminal for display. As such, the navigator functions are actually distributed between the service provider equipment and the subscriber's equipment. Such distribution provides an enjoyable, real-time interactive session that allows the user to rapidly navigate through a plethora of menus to find particular information, which they desire to view.

A method and apparatus for masking the effects of latency within an information distribution system. The apparatus comprises a set top terminal that requests and receives information from an information server within the information distribution system. The information is generally displayed upon a conventional television that is coupled to the set top terminal. The set top terminal contains a central processing unit and an information stream decoder that are programmed to implement the method. The method is a routine which is executed when a subscriber selects certain functions, usually via a remote control, that are available for the set top terminal to perform. Upon execution, the method recalls a predefined image from memory and begins to fade the presently displayed image into a predefined image, e.g., a white screen. Simultaneously, the presently playing sound is also faded into the predefined sound, e.g., no sound. The decoder within the set top terminal is reset to flush from its buffer and residual sound or video information from the previously decoded video. Lastly, once the new video stream has arrived and begins to be decoded, the set top terminal fades up from the pre-defined image to the new video stream and from the pre-defined audio to the audio stream that accompanies the video stream. At this point, the subscriber's selected function has been fully implemented without display of the detrimental affects usually associated with a latency delay.
