We have developed a system that allows us to index and deliver audio and video over the Internet. The system has been in continuous operation since March 1998 within the company. The design of our system differs from previous systems because 1) the indexing can be based on an annotation stream generated by robust transcript alignment, as well as closed captions, and 2) it is a distributed system that is designed for scalable, high performance, universal access through the World Wide Web. Extensive tests of the system show that it achieves a performance level required for Internet-wide delivery. This paper discusses our approach to the problem, the design requirements, the system architecture, and performance figures. It concludes by showing how the next generation of annotations from speech recognition and computer vision can be incorporated into the system.
