Perceptual Coding of High-Quality Digital Audio

Christof Faller, Karlheinz Brandenburg

This paper introduces high-quality audio coding using psychoacoustic models. This technology is now abundant, with gadgets named after a standard (mp3 players) and the ability to play high-quality audio from literally billions of devices. The usual paradig ...

User Performance in Interaction with Web-GIS: A Semi-Automated Methodology Using Log-Files and Streaming-Tools

François Golay, Jens Ingensand

This paper describes a framework of methods for the measurement and evaluation of users' performance in interaction with a web-GIS. The framework involves testing of a system with real-world users, streaming of the user's screen during the evaluation and t ...

Stay Tuned! An Automatic RSS feeds Trans-coder

Daniel Thalmann, Patrick Salamin, Frédéric Vexo

News aggregators are widely used to read RSS feeds but they require the user to be in front of a screen. While moving, people usually do not have any display, or very small ones. Moreover, they need to perform actions to get access to the news: download a ...

Thanks to geolocalized remote control : the sound will follow

Daniel Thalmann, Frédéric Vexo, Mathieu Hopmann

Dematerialized music and MP3 players offer to the user the possibility of carrying his musical content everywhere. However, at home, the music collection is generally not centralized, split between different rooms and audio supports (CDs, MP3s, etc). In th ...

Network Resource Allocation for Competing Multiple Description Transmissions

Suhas Diggavi

Providing real-time multimedia services over a best-effort network is challenging due to the stringent delay requirements in the presence of complex network dynamics. Multiple description (MD) coding is one approach to transmit the media over diverse (mult ...

Fault-tolerance of capillary multi-path routing for real-time multimedia streaming with forward error correction

Roger Hersch, Emin Gabrielyan

Using forward error correction (FEC) in off-line streaming, permitting large buffers, yields spectacular results, but real-time streaming puts hard restrictions on the buffer size and therefore does not allow FEC to deal with long link failures on a single ...

Updates in Highly Unreliable, Replicated Peer-to-Peer Systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

In this paper we study the problem of updates in truly decentralised and self-organising systems such as pure P2P systems. We assume low online probabilities of the peers (
