TV Watcher: Distributed Media Analysis and Correlation
The explosion of available content in broadcast media has created a desperate
need for applications and prerequisite system architectures to support
automatic capture, filtration, categorization, correlation, and higher level
inferencing of streaming data from distributed sources. We present TV Watcher,
an archetypical example of such an application. TV Watcher performs
user-controlled correlation of live television feeds and allows the user to
automatically navigate through the available channels based on content of
interest. We introduce the Symphony architecture for distributed real-time
media analysis and delivery to meet the system requirements for applications
with such needs. TV Watcher is built on top of the Symphony architecture, and
currently uses closed-captioning information to correlate television
programming. We present the results of a user study that shows the correlation engine is consistently able to pick significantly useful and relevant content.
