Error-Free Material: New Software by Fraunhofer IDMT Inspects Audio-Visual Media Content

Scientists of the Ilmenau Fraunhofer Institute for Digital Media Technology IDMT have developed an innovative technology that automatically recognizes and visually highlights errors in digital audio and video footage.

An additional video analysis tool helps to identify and arrange i. a. representative scenes in movies, thus allowing better organization and management of digital media content.

“AVInspector” analyses audio and video content in real-time and automatically detects errors and quality issues, e.g. blocking artefacts, ringing or blurring. There are special analysis modules that recognize errors according to defined criteria and visually highlight them depending on the intensity of the error detected. Via timecode, the exact position of the faulty image or sequence is located. This insures perfect footage already during the production process.

AVInspector opens up new opportunities for TV and Radio producers. The whole video and audio content can be automatically checked for errors, making the workflow much easier. Broadcasting and video archives benefit from Fraunhofer IDMT's software, too. Dr. Uwe Kühhirt, head of the Audio-visual Systems group at Fraunhofer IDMT, explains: “Our automated and continuous error detection ensures that only perfect material is edited, published and archived. This saves not only work, but also time and costs, since there is no tedious manual screening for errors any longer.“ In addition, this technology can also be used in broadcasting networks to check the quality of the signals on the receiver's side and to optimize it accordingly.

AVInspector is supplemented by additional video analysis tools that automatically recognize and compile the most representative keyframes, shots and scenes in a film or video clip. This way, the material in large databases can be managed easier, comprehensive video archives can be searched quicker and film makers are supported in drama production and compilations of films and videos.

Fraunhofer IDMT presents AVInspector at the International Trade Fair for broadcasting and television, IBC, in Amsterdam from September 9 to 13, 2011. Visit us at the Fraunhofer booth in hall 8, stand B 80.

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...

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...
