  • Joint Source/FEC Rate Selection for Quality-Optimal MPEG-2 Video Delivery  
  • by Pascal Frossard, Olivier Verscheure — 2001 — IEEE Transactions on Image Processing
  • …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 distortion given a set of video and network parameters. We first derive the set of equati…

  • Content-based MPEG-2 Structuring and Protection  
  • by Pascal Frossard, Olivier Verscheure — 1999
  • …We address a new error-resilient scheme for broadcast-quality interactive MPEG-2 video streams to be transmitted over lossy packet networks. A new scene-complexity adaptive mechanism, namely Adaptive MPEG-2 Information Structuring and Protection (AMISP) is introduced. AMISP lies on an information st…

  • Joint Source/FEC Rate Selection for Optimal MPEG-2 Video Delivery  
  • by Pascal Frossard, Olivier Verscheure — 2000 — in Proccedings of IEEE International Conference on Multimedia and Expo
  • …This paper deals with the optimal allocation of MPEG-2 encoding and media-independent FEC rates under a total given bandwidth. The optimality is defined in terms of minimum perceptual end-toend distortion given a set of video and network parameters. We first derive the set of equations leading to th…

  • AMISP: A Complete Content-Based MPEG-2 Error-Resilient Scheme  
  • by Pascal Frossard, Olivier Verscheure — 2001 — IEEE Transactions on Circuits and Systems for Video Technology
  • …We address a new error-resilient scheme for broadcast quality MPEG-2 video streams to be transmitted over lossy packet networks. A new scene-complexity adaptive mechanism, namely Adaptive MPEG-2 Information Structuring (AMIS) is introduced. AMIS modulates the number of resynchronization points (i.e.…

  • Adaptive MPEG-2 Information Structuring  
  • by Pascal Frossard , Olivier Verscheure — 1998
  • …This work addresses the optimization of TV-resolution MPEG-2 video streams to be transmitted over lossy packet networks. This paper introduces a new scene-complexity adaptive mechanism, namely the Adaptive MPEG-2 Information Structuring (AMIS) mechanism. AMIS adaptively modulates the number of resyn…

  • MPEG-2 over lossy packet networks QoS Analysis and Improvement  
  • by Pascal Frossard, Olivier Verscheure — 1998
  • …This work addresses the quality of service (QoS) analysis and optimization of TV-resolution MPEG-2 video streams to be transmitted over packet networks facing a given packet loss probability. The first contribution of this work resides in the analysis of the end-to-end QoS of MPEG-2 video streams tr…

  • Batched Patch Caching for Streaming Media  
  • by Pascal Frossard, Olivier Verscheure — 2002
  • …This letter elaborates on a scheme that combines batch patching at an origin server and prefix/interval caching at an edge server receiving the clients' requests. We derive a cost function that factors in the aggregate backbone rate, the cache occupancy, and the disk bandwidth utilization. We define…

  • Joint Server Scheduling and Proxy Caching for Video Delivery  
  • by Olivier Verscheure, Chitra Venkatramani, Pascal Frossard, Lisa Amini — 2001 — in Proc. 6 th International Workshop on Web Caching and Content Distribution
  • …We consider the delivery of video assets over a besteffort network, possibly through a caching proxy located close to the clients generating the requests. We are interested in the joint server scheduling and prefix/partial caching strategy that minimizes the aggregate transmission rate over the back…
