Price-based Controller for Quality-Fair HTTP Adaptive Streaming

Pascal Frossard, Laura Toni, Stefano D'Aronco

HTTP adaptive streaming (HAS) has become the universal technology for video streaming over the Internet. Many HAS system designs aim at sharing the network bandwidth in a rate-fair manner. However, rate fairness is in general not equivalent to quality fair ...

We propose and analyze an online algorithm for reconstructing a sequence of signals from a limited number of linear measurements. The signals are assumed sparse, with unknown support, and evolve over time according to a generic nonlinear dynamical model. O ...

A Versatile Spectrum Shaping Scheme for Communicating Beyond Notches in Multi-Drop Interfaces”

Mohammad Amin Shokrollahi, Seyed Armin Tajalli, Christoph Walter, Ali Hormati, Kiarash Gharibdoust

This paper proposes a signal shaping technique to increase the data rate of high-speed SerDes communication systems over multi-drop bus interfaces. This scenario creates a channel with deep notches in its spectrum, and therefore the effective data rate in ...

Towards high dynamic range extensions of HEVC: subjective evaluation of potential coding technologies

Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek

This paper reports the details and results of the subjective evaluations conducted at EPFL to evaluate the responses to the Call for Evidence (CfE) for High Dynamic Range (HDR) and Wide Color Gamut (WCG) Video Coding issued by Moving Picture Experts Group ...

Exploring MPEG HEVC decoder parallelism for the efficient porting onto many-core platforms

Marco Mattavelli, Simone Casale Brunet, Claudio Paolo Alberti, Damien Jack De Saint Jorre

MPEG High Efficient Video Coding (HEVC) is likely to emerge as the video coding standard for HD and Ultra-HD TV resolutions. The two elements that push HEVC beyond the previous standards are a higher compression efficiency of about a factor of two, and the ...

Ultra high definition (UHD) TV is rapidly replacing high definition (HD) TV but little is known of its effects on human visual attention. However, a clear understanding of this effect is important, since accurate models, evaluation methodologies, and metri ...

Audiovisual focus of attention and its application to Ultra High Definition video compression

Touradj Ebrahimi, Martin Rerabek, Jong Seok Lee, Hiromi Nemoto

Using Focus of Attention (FoA) as a perceptual process in image and video compression belongs to well-known approaches to increase coding efficiency. It has been shown that foveated coding, when compression quality varies across the image according to regi ...
