Patent Images
1. A method of generating an interactive user interface comprising:
- generating, within a head end of an information distribution system, a plurality of bitstreams representing video imagery associated with respective portions of an encoded user interface, each of said bitstreams including a respective user interface page comprising a common moving image region and a respective graphical region, said respective graphical regions comprising video imagery associated with user selectable objects; and
broadcasting said encoded user interface;
said user interface being adapted for use by a subscriber selectively decoding and presenting said common video and respective graphical region for each of at least one 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 video region and a respective graphical region;
extracting from said transport stream a first selected bitstream;
decoding and presenting said selected bitstream to produce a corresponding first user interface page;
selecting, in said first user interface page, an object that identifies a second bitstream; and
decoding said second selected bitstream without resetting a buffer in a decoder. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
