Playback 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 ...

Adaptive video streaming in lossy networks: versions or layers?

Pascal Frossard, Ivana Radulovic

This paper tackles low delay adaptive video streaming over error-prone networks. Our framework consists of an encoding station, an edge server and a set of clients with various access rates. The edge server is capable of performing simple error concealment ...

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 ...

MPEG-7 Description for Scalable Video Reconstruction

Touradj Ebrahimi

We present an MPEG--7 compliant description of video sequences for scalable transmission and reconstruction. The proposed method is content-based and permits efficient and flexible video coding while keeping the benefits of textual descriptions in database ...

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 ...

Joint Source/FEC Rate Selection for Quality-Optimal MPEG-2 Video Delivery

Pascal Frossard

This paper deals with the optimal allocation of MPEG-2 encoding and media-independent Forward Error Correction (FEC) rates under a total given bandwidth. The optimality is defined in terms of minimum perceptual end-to-end distortion given a set of video an ...

MPEG-4 natural video coding - An overview

Touradj Ebrahimi

This paper describes the MPEG-4 standard, as defined in ISO/IEC 14496-2. The MPEG-4 visual standard is developed to provide users a new level of interaction with visual contents. It provides technologies to view, access and manipulate objects rather than p ...

Designing new network adaptation and ATM adaptation layers for interactive multimedia applications

Multimedia services, audiovisual applications composed of a combination of discrete and continuous data streams, will be a major part of the traffic flowing in the next generation of high speed networks. The cornerstones for multimedia are Asynchronous Tra ...

Reliable Transmission of MPEG-2 VBR Video Streams over New Network Adaptation and ATM Adaptation Layers

Pascal Frossard, Olivier Verscheure

This paper adresses the transmission of VBR MPEG-2 video streams on top of both Network Adaptation (NAL) and ATM Adaptation Layers (AAL) for real-time multimedia applications. The NAL, specific to MPEG-2, provides a selective data protection mechanism base ...
