Today, SnapStream's primary means of searching television recordings is closed captioning data embedded inside of all television broadcasts. Today, the FCC requires most broadcasters to include closed captioning data on all of their television programs. There are some exemptions to the requirement by the FCC, but in general, most television programs in the United States include closed captioning data. 

SnapStream's TV search technology indexes the closed captioning stream in real-time as the broadcast airs and retrieves relevant, high-quality results in an optimized format using proprietary algorithms and linguistic intelligence.
