Abstract
Real-time metadata tracks recorded to media streams allow search and analysis operations in a variety of contexts. Search queries can be performed using information in real-time metadata tracks such as closed captioning, sub-title, statistical tracks, miscellaneous data tracks. Media streams can also be augmented with additional tracks. The metadata tracks not only allow efficient searching and indexing, but also allow insertion of content specific advertising during appropriate portions of a media stream based on the content of the metadata tracks.
