Abstract

An enhanced interactive television broadcast is disclosed wherein an audio/video broadcast is viewed on a first display system, and an “enhancement” to the broadcast is simultaneously viewed or experienced on a second, separate display system. The “enhancement” is synchronized to the broadcast, and delivered to a user as a code fragments, such as a JavaScript message. URLs are not required. Portions or elements of a web page are reduced to single code fragments, rendered client-side upon receipt. The invention implements Network Time Protocol (NTP) to synchronize the client'"'"'s application clock to global time. Messages, or JavaScript code fragments, are time-stamped and evaluated based on the client'"'"'s application clock.

18. The method of claim 8, further comprising;

receiving the input from the user of the client device during a limited interactivity period;

executing software on the client device to analyze the input;

assigning points to the user according to the analyzed input only during the limited interactivity period, such that the user accumulates an earned score.

19. A method for providing enhanced television broadcasting, the method comprising:

selecting a common time for a synchronized presentation of content an audio and video signal and a related enhancement, the related enhancement including at least one instruction; and

sending the related enhancement over a network for receipt by a client device,

wherein the related enhancement includes at least one instruction correlated to the content of the audio and video signal to be interpreted by the client device to locally modify at the client device enhanced content to be displayed in an exclusively local interaction based on the interpreted instruction.

20. The method for providing enhanced television broadcasting of claim 19 further comprising:

assigning a group name to a group, the group capable of being accessed by a plurality of users;

assigning a password to the group, such that the group name and the password are uniquely associated;

storing the uniquely associated group name and password;

receiving a query group name and a query password from a joining user;

comparing the query group name and query password received from the joining user to the stored uniquely associated group name and password;

providing the joining user access to the group if the query group name and query password are identical to the stored uniquely associated group name and password; and

reporting to each user having access to the group the earned score of all users having access to the group.

21. The method for providing enhanced television broadcasting of claim 19 further comprising sending the related enhancement separately from the audio and video signal.

22. The method for providing enhanced television broadcasting of claim 19 further comprising:

ranking the earned scores of the plurality of users having access to the group to determine a relative score for each user having access to the group; and

reporting, to each user having access to the group, the relative scores,

wherein the reporting comprises displaying the relative scores in ranked order within a leaderboard.
