Invertible Extractors and Wiretap Protocols

Mohammad Amin Shokrollahi, Mahdi Cheraghchi Bashi Astaneh

A wiretap protocol is a pair of randomized encoding and decoding functions such that knowledge of a bounded fraction of the encoding of a message reveals essentially no information about the message, while knowledge of the entire encoding reveals the messa ...

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 ...

A Network Coding Approach to Network Tomography

Christina Fragouli

Network tomography aims at inferring internal network characteristics based on measurements at the edge of the network. In loss tomography, in particular, the characteristic of interest is the loss rate of individual links. There is a signiﬁcant body of wo ...

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 ...

Capacity Achieving Codes from Randomness Conductors

Mahdi Cheraghchi Bashi Astaneh

We give a general framework for construction of small ensembles of capacity achieving linear codes for a wide range of (not necessarily memoryless) discrete symmetric channels, and in particular, the binary erasure and symmetric channels. The main tool use ...

Code Construction for Multiple Sources Network Coding

Christina Fragouli, Suhas Diggavi

In several wireless applications multiple sources transmit information to one or more receivers, many times over unknown topologies. This is especially so in mobile networks where learning the topology may have prohibitive complexity. Network coding techni ...

Dense Disparity Estimation in a Multi-view Distributed Video Coding System

Thomas Maugey

Distributed video coding (DVC) is a recent paradigm which aims at transferring part of the coding complexity from the encoder to the decoder. The performance of such a coding scheme strongly depends on the capacity to estimate correlation at the decoder an ...

Media coding for streaming in networks with source and path diversity

Pascal Frossard, Nikolaos Thomos

Novel network architectures such as overlay networks offer significant diversity that can compensate for the lack of strict quality of service in today's communication infrastructures. In order to take advantage of this diversity for delay-sensitive media ...

Multiple Description Coding for Stationary Gaussian Sources

Suhas Diggavi, Jun Chen

We consider the problem of multiple description coding for stationary Gaussian sources under the squared error distortion measure. The rate region is characterized for the 2-description case. It is shown that each supporting line of the rate region is achi ...
