The virtue of patience in low complexity scheduling of packetized media with feedback

Pascal Frossard, Christophe De Vleeschouwer

We consider streaming of pre-encoded and packetized media over best-effort networks in presence of acknowledgment feedbacks. We first review the rate-distortion optimization framework in such scenarios. Given an estimation of future transmission resources, ...

Time-complexity bounds on agreement problems

Partha Dutta

In many distributed systems, designing an application that maintains consistency and availability despite failure of processes, involves solving some form of agreement. Not surprisingly, providing efficient agreement algorithms is critical for improving th ...

Packetized 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 ...

Fast Index Assignment for balanced N-Description Scalar Quantization

Pascal Frossard, Ivana Radulovic

In this paper, we address the design of any number of balanced descriptions using multiple description scalar quantization (MDSQ), based on fast index assignment. The proposed scheme has the advantages of low complexity, and the possibility of being extend ...

Distortion Optimized Multipath Video Streaming

Pascal Frossard, Dan Jurca

This paper addresses the problem of choosing the best streaming policy for distortion optimal multipath video delivery, under delay constraints. The streaming policy consists in a joint selection of the video packets to be transmitted, as well as their sen ...

Optimal FEC Rate for Media Streaming in Active Networks

Pascal Frossard, Dan Jurca

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 ...

Early Local Decisions in Distributed Agreement

Rachid Guerraoui, Bastian Pochon, Partha Dutta

When devising a distributed agreement algorithm, it is common to minimize the time complexity of global decisions, which is typically measured as the number of communication rounds needed for all correct processes to decide. In practice, what we might want ...

Securing Media for Adaptive Streaming

Pascal Frossard

This paper describes the ARMS system which enables secure and adaptive rich media streaming to a large-scale, heterogeneous client population. The secure streaming algorithms ensure end-to-end security while the content is adapted and streamed via intermed ...

A No-Reference Perceptual Blur Metric

Touradj Ebrahimi, Pina Marziliano, Frédéric Dufaux, Stefan Winkler

In this paper, we present a no-reference blur metric for images and video. The blur metric is based on the analysis of the spread of the edges in an image. Its perceptual significance is validated through subjective experiments. The novel metric is near re ...
