    Abstract: An interactive television program guide system is provided in which a viewer may direct a television to simultaneously display a selected television program, a program guide display, and a program guide video window. A viewer may use the program guide video window to browse video of programs shown on the program guide display while continuing to view a previously selected program in the background. The program guide display may display video on demand (VOD) programs, programs to be broadcast in the future, and programs currently being broadcast on other channels. The viewer may browse through programs on the program guide display using a variety of keys on a remote control unit. The viewer may direct the program guide to swap audio and video signals back and forth between programs shown in the video window and programs shown on the background screen.

    Abstract: A program guide system is provided in which an interactive television program guide that is implemented at least partially on user television equipment receives program listings data and real-time data such as sports scores, news data, and the like. The real-time data may be stored in a database maintained by the program guide, so that the program guide may access the stored real-time data at a later time. Updated program listings information may be provided to the program guide as part of the data stream in which the real-time data is provided. Unique keys may be generated for the program listings data and real-time data associated with each live event. The keys may be compared at the program guide to determine which program listings correspond to which items of real-time data. A controllable ticker may be displayed on top of a television program on the user television equipment. The controllable ticker may be sponsored. Different types of real-time data may be assigned different expiration times. When data has expired it may be removed from the database.

    Abstract: The present invention relates to a method of producing a signature characterizing an interval of a video signal representing a picture for use in broadcast segment recognition. The signature is produced based on portions of the video signal representing corresponding regions of the picture. The invention also serves to produce a corresponding mast word including a plurality of bit values each representing a reliability of a corresponding value of the signature. The first signature is formed having a plurality of values each of which is based on a respective one of the portions of the video signal. A second signature is formed also having a plurality of values each based on respective ones of a plurality of shifted portions of the video signal. The shifted portions each corresponds to a respective one of the video signal portions and has a location displaced from a location of the respective one of the portions by a predetermined amount, such that each value of the first signature corresponds to a value of the second signature. The respective values of the first and second signatures are compared and bit values of the mask word are established based on this comparison.

    Abstract: Broadcast segment recognition systems and methods are provided in which a signature representing a monitored broadcast segment is compared with broadcast segment signatures in a data base representing known broadcast segments to determine whether a match exists. Criteria for determining the validity of such a match are provided. In addition, signatures characterizing respective intervals of a broadcast signal exhibiting correlation are produced by generating a difference vector for each respective interval and carrying out vector transformations of the different vectors to reduce such correlation. Also, a broadcast segment recognition data base is updated by monitoring a broadcast signal to detect signal events indicating possible broadcast segments of interest in which at least two alternative segments of interest are detected by assigning priority to one of the two segments based upon predetermined criteria. A signature characterizing a broadcast signal interval is produced including a plurality of digital words each characterizing a respective sub-interval thereof by selecting at least one such digital word based on predetermined digital word distribution criteria, match probability and a degree of signal difference between the respective sub-interval and adjacent portions of the signal.
