1. A method of generating an interactive user interface comprising:
- generating, within a head end of an information distribution system, a plurality of bitstreams that each represent a separate portion of video imagery associated with an encoded user interface, each at said bitstreams including a respective user interface page comprising a common moving image region and a separate graphical region having video imagery associated with user selectable objects; and
broadcasting said plurality of bitstreams so as to send the interactive user interface to a subscriber;
said user interface being adapted for use by the subscriber to selectively present said common moving image region and a separate graphical region of a bitstream of said plurality of bitstreams.

Abstract
Method and apparatus for generating, transmitting and receiving a user interface for an interactive information distribution system. 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 within the subscriber equipment and on a system level within the head end. One embodiment of the user interface is an interactive program guide.

8. A method of using an interactive user interface comprising:
- receiving a transport stream that contains a plurality of bitstreams representing a respective plurality of encoded user interface pages, each page comprising a common moving image region and a separate graphical region;
extracting from said transport stream a first selected bitstream of said plurality of bitstreams;
decoding and presenting said selected bitstream to produce a corresponding first user interface page having a common moving image region and a separate graphical region;
selecting, in said first user interface page, an object that identifies a second bitstream of said plurality of bitstreams; and
decoding said second selected bitstream without resetting a buffer in a decoder. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
