ABSTRACT:
A user interface for an interactive information distribution system comprising a graphics region, a video region and a mask/reveal layer. The user interface is generated in a head end of the system as a digital bitstream and transmitted to subscriber equipment for display. Operation of the user interface is facilitated by functions on both a local level with the subscriber equipment and on a system level within the head end. One embodiment of the user interface is an interactive program guide.
