Soundtrack Text Search
 
Doovle uses the textual transcript (narrative and dialogue taken from the soundtrack) to enable users to search for words and phrases that occur in any piece of video content.
 
The Doovle search index contains a store of all the narrative and dialogue in each indexed content asset along with timing information for when each line or phrase or quotation occurs. This is much like a set of subtitles which are essentially lines of text and associated timing points.
 
But video content does not have to be subtitled in order to be made searchable with Doovle. Our unique assisted tagging solutions enable content owners to generate Doovle indexes with arbitrary text tags set against precise timing points in the content.
 
Results Delivery
 
When users search, the results appear as a Google-like list of all the scenes in all the video titles in the database that contain narrative and dialogue or Doovle tags that match what was searched for. Against each result is shown a still image of the exact scene and the text line that matched.
 
To play the scene of video, users just click each search result and the correct video is called from its streaming server or CDN and is made to play from the correct point.

Integration & Interface
 
Doovle can be integrated into any web site design or IPTV channel structure. In the example below, taken from a video lecture search project commissioned by the Howard Hughes Medical Institute, the user has searched for "Human Genome". The Doovle search results are served seamlessly into the web interface enabling the user to watch any of the matched scenes with a single click:

Assisted Tagging Solutions
 
Doovle can also provide content owners with powerful tools to generate time-specific text "tags" that can make any kind of video content searchable, whether it has a soundtrack or a transcript or not.
 
Doovle's assisted tagging can be managed by administrators or can be provided to public viewing audiences who can set their own time-specific tags to "save" scenes they want to be able to search for and jump straight to at any time.
