Network coding: from theory to media streaming

Pascal Frossard, Nikolaos Thomos

Network coding has recently emerged as an alternative to traditional routing algorithms in communication systems. In network coding, the network nodes can combine the packets they receive before forwarding them to the neighbouring nodes. Intensive research ...

Heterogeneous Gossip

Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Davide Frey

Gossip-based information dissemination protocols are considered easy to deploy, scalable and resilient to network dynamics. Load-balancing is inherent in these protocols as the dissemination work is evenly spread among all nodes. Yet, large-scale distribut ...

Delay-based overlay construction in P2P video broadcast

Pascal Frossard

We consider streaming video content over an overlay network of peer nodes. Each of the nodes employs a mesh-pull mechanism to organize the download of data units from its neighbours. We propose a novel algorithm for constructing the distribution overlay, w ...

Network coding of rateless video in streaming overlays

Pascal Frossard, Nikolaos Thomos

We investigate the problem of collaborative video streaming in overlay networks. We exploit path and source diversity, as well as basic processing capabilities of network nodes in order to increase the overall throughput and improve the video quality at th ...

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 ...

Randomized network coding for UEP video delivery in overlay networks

Pascal Frossard, Nikolaos Thomos

This paper presents a receiver-driven video delivery algorithm that exploits a novel Randomized Network Coding (RNC) scheme for unequal error protection (UEP). The main idea of our approach is to account for the unequal importance of media packets in the n ...

P2P video broadcast with latency and utility optimization

Pascal Frossard

We consider the problem of mesh-pull based video broadcast in peer-to-peer networks. We propose a novel algorithm for constructing the distribution overlay, where peers are arranged in neighborhoods that exhibit similar latency values from the origin media ...

Stretching Gossip with Live Streaming

Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Davide Frey

Gossip-based information dissemination protocols are considered easy to deploy, scalable and resilient to network dynamics. They are also considered highly ﬂexible, namely tunable at will to increase their robustness and adapt to churn. So far however, the ...

Multimodal Data Flow Controller

Danil Korchagin

In this paper, we describe a multimodal data flow controller capable of reading most multichannel sound cards and web cameras, synchronising media streams, being a server to stream captured media over TCP in raw format, being a client to receive media stre ...

Resource allocation and adaptive scheduling for scalable video streaming

Jean-Paul Wagner

The obvious recent advances in areas such as video compression and network architectures allow for the deployment of novel video distribution applications. These have the potential to provide ubiquitous media access to end users. In recent years, applicati ...
