NAB 2015 - Automatic Analysis of Audio and Video Material


At NAB Show, the world’s largest convention for the digital media industry, taking place April 13 – 16 in Las Vegas (USA), Fraunhofer IDMT will be presenting it’s A/V Analyzing Toolbox, a collection of components for analyzing and optimizing processes for broadcasting, distributing, and archiving digital content.

Besides a number of previously introduced components, such as quality control of audio and video content (QC Components) or automatic measurement of the exact amount of music in radio and TV programs, the Fraunhofer experts will be showcasing a new tool for efficient management of video data in large archives.

Thanks to the new Video Segment Matching functionality, identical video segments as well as their exact position and length can be recognized automatically.

Fraunhofer IDMT

Broadcasting corporations and video archive operators usually use material from multiple sources (news agencies, private users, their own archives, etc.). That material is then edited by means of cuts, insertions/fade-ins, or the replacement of audio tracks. Identifying the broadcasting formats in which content is used and the channels through which it is distributed becomes increasingly difficult this way.

--- Video Segment Matching ---

To counter this problem, Fraunhofer IDMT has developed the Video Segment Matching, a software which recognizes identical video segments in different videos (even if content has been edited or transcoded), and determines their exact position and length. The tool extracts fingerprints from the videos under analysis, which are then matched against each other in a multi-stage, automated process. Users of the software benefit e. g. from more accurate accounting of copyright protected content, the detection of duplicates in archives, and improved management and storage of data.

Regarding the QC Components offered by the A/V Analyzing Toolbox, the Fraunhofer experts will be presenting new and enhanced functionalities, allowing automatic detection of errors and quality issues in digital audio and video content.

--- Music Detection ---

In addition, the A/V Analyzing Toolbox includes a component for automatic measurement of the exact amount of music in radio and TV programs. Copyright agencies may use this tool for accurate accounting and to make more efficient queries of programs, as music segments can be filtered out before concrete pieces of music are searched for by title.

Visitors interested in the A/V Analyzing Toolbox may feel free to stop by the Fraunhofer booth SU3714 in the South Upper Hall.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
