NAB Show 2016: Searching for traces in the digital content jungle

15.04.2016

At this year’s NAB Show, the world’s largest convention for the digital media industry, taking place April 18 – 21 in Las Vegas, Fraunhofer IDMT for the first time will be presenting its “Audio Forensics Toolbox”. The software package allows users to detect traces of previous editing and encoding steps in audio material, in order to assess the quality of recordings and optimize workflows in production processes.

-- Assessing the quality of audio content --


The Audio Forensics Tools help to identify the used recording devices.

Fraunhofer IDMT

There are many application contexts in which the quality of audio material is critical for its further use. Media archives or providers of audio and video files, for example, need to validate digital content quickly and easily in terms of whether the content has been edited or encoded at some point in time.

Such validation enables users to determine the quality of the material and optimize their own editing and encoding processes.

-- Easy creation and linking of metadata --

In the course of editing and encoding audio content, characteristic traces (i.e. metadata) are left in the material. The “Audio Forensics Toolbox” allows users to identify the devices and microphones used for a recording, detect cuts and splices in audio material, and find out whether certain segments have been reused in a new context.

This helps content aggregators and broadcasters avoid redundancies and inconsistencies in the material they use.

-- A/V inspector --

Alongside with the “Audio Forensics Toolbox”, Fraunhofer IDMT will be presenting an update of its “AV Analyzing Toolbox”, which can be used to optimize processes for broadcasting, distributing, and archiving digital content. This Toolbox comprises various components for automatic identification of flaws and quality deficiencies in digital audio and video content.

In addition, the Toolbox comes with a video segment matching component, which recognizes identical video segments across different videos (even if the content has been edited or transcoded) and determines their exact position and length.

Another component of the Toolbox allows automatic measurement of the exact amount of music in radio and TV programs, offering support in the context of accurate accounting and more efficient queries of programs.

The institute presents its tools for analyzing audio and video content at the Fraunhofer booth SU6716 in the South Upper Hall.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
