"Robust Media Search" Technology For Searching For Audio/Video Data In Our Surroundings

By NTT Science and Core Technology Laboratory Group

When you hear a good song on the street, or see an interesting item on TV, do you ever want to find out more information about what you're hearing or seeing? Searching for information on a distorted signal captured by a mobile phone or camera is possible with NTT's Robust Media Search technology.

Media Search Technology

The media search basically examines the similarity between a "query signal," which is a fragment of audio or video, and each section of "stored signals" in a database to extract various information related to the query.

In a media search, the main goals are the accuracy and high speed.

NTT has been studying this from early on and led the world by developing Fast Media Search technologies, such as the Time-series Active Search and the Learning-based Active Search.

Now we have developed much faster and more accurate searching technology -- the Robust Media Search.
