摘要:
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.
