Gossiping Capabilities
Rachid Guerraoui, Anne-Marie Kermarrec, Maxime Monod, Davide Frey
Gossip-based protocols are now acknowledged as a sound basis to implement collaborative high-bandwidth content dissemination: content location is disseminated through gossip, the actual contents being subsequently pulled. In this paper, we present HEAP, HE ...
2008Resource allocation and adaptive scheduling for scalable video streaming
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 ...
EPFL2008A fast local descriptor for dense matching
Pascal Fua, Vincent Lepetit, Engin Tola
We introduce a novel local image descriptor designed for dense wide-baseline matching purposes. We feed our descriptors to a graph-cuts based dense depth map estimation algorithm and this yields better wide-baseline performance than the commonly used corre ...
2008Adaptive and robust media streaming over multiple channels with bursty losses
Pascal Frossard, Jean-Paul Wagner
This paper addresses the problem of efficiently delivering a layered media stream from multiple senders to a single receiver, over channels that present correlated packet loss patterns. Using a digital fountain approach, the performance of a distributed st ...
2007Adaptive media streaming over multipath networks
With the latest developments in video coding technology and fast deployment of end-user broadband internet connections, real-time media applications become increasingly interesting for both private users and businesses. However, the internet remains a best ...
EPFL2007Enabling Adaptive Video Streaming in P2P Systems
Pascal Frossard, Dan Jurca, Jean-Paul Wagner
Peer-to-peer (P2P) systems are becoming increasingly popular due to their ability to deliver large amounts of data at a reduced deployment cost. While P2P systems foster the development of novel media applications, they also represent an interesting altern ...
2007Playback Delay and Buffering Optimization in Scalable Video Broadcasting
Pascal Frossard, Jean-Paul Wagner
This paper addresses the problem of optimizing the playback delay experienced by a population of heterogeneous clients, in video streaming applications. We consider a typical broadcast scenario, where clients subscribe to different portions of a scalable v ...

Pascal Frossard, Jean-Paul Wagner
This paper addresses the problem of optimizing the playback delay experienced by a population of heterogeneous clients, in video streaming applications. We consider a typical broadcast scenario, where clients subscribe to different portions of a scalable v ...
2005Packetized Media Streaming with Comprehensive Exploitation of Feedback Information
Pascal Frossard, Christophe De Vleeschouwer
This paper addresses the problem of streaming packetized media over a lossy packet network, with sender-driven (re)transmission using acknowledgement feedback. The different transmission scenarios associated to a group of interdependent media data units ar ...
2005Optimal FEC Rate for Media Streaming in Active Networks
This paper addresses the problem of optimal channel rate allocation for media streaming in active networks, where intermediate nodes are able to perform basic FEC decoding/encoding operations. FEC performance is analyzed in the case of hop-by-hop FEC prote ...
