Geisha Grid Enabled Infrastructure for Service oriented High definition media Applications

  1. 1. GEISHA Grid Enabled Infrastructure for Service oriented High definition media Applications Geisha Closing Event March 10, 2009
  2. 2. Agenda ! Welcome & introduction Dietrich Van der Weken, Piet Demeester 13:15 – 13:30 ! HD media-infrastructure Luc Andries 13:30 – 14:45 ! Grid technology for next generation media processing Bruno Volckaert 14:45 – 15:10 ! Break ! Formats for high-definition television: a challenge Marc Jacobs, Dieter Van Rijsselbergen 15:40 – 16:10 ! Automating workflows with service oriented media applications Dietrich Van der Weken, Didier Clabaut, Stein Desmet 16:10 – 17:00
  3. 3. Introduction – Setting the scene 4
  4. 4. Introduction – Setting the scene 2005 – 2006: IBBT project FIPA File based Integrated Production Architecture ! Adoption of file-based paradigm for media production ! Central FC-storage platform suitable for radio and SD TV production Challenges with transition to HD: ! Increasing bandwidth and capacity requirements ! Backup/restore paradigms ! Optimization of data flows ! Adoption of GRID enabled computing for processor-intensive processes ! Multiple formats, transcoding ! More flexible integration between central infrastructure and work centres March 2007 – February 2009: IBBT project GEISHA Grid Enabled Infrastructure for Service oriented High definition media Applications 5
  5. 5. WP1-2: Media Infrastructure ! HD model expanded ! Improved WARP cluster Redundant Independent scaling Component optimization ! Client – server transport Technology Protocols ! IP Network behaviour in Media The “Quantum View” ! Clustered HSM Secundary storage cluster Cluster-2-cluster transport / ILM /backup-recovery ! Transcoding on cell 6 PS3 demo
  6. 6. WP3 – Media Grid ! Grid computing ! Special context of file based media production / distribution environment ! Evaluation of transcoding performance on Grid Middleware ! Grid simulation ! MediaNSG – MediaGrid simulator ! Allows evaluation of scheduling and resource management algorithms ! Comparative study ! Measured distributed transcoding application performance ! Simulation of distributed transcoding application performance 7
  7. 7. WP4 – Advanced Media and File Formats ! From tape to SD to HD ! tape: possibilities determined/limited by technology ! SD: some extra possibilities and options ! evolution to HD: many choices to be made ! raster formats: 720p50, 1080i25, 1080p25,1080p50 ! video codecs + parameters: DVCProHD, MPEG-2, DNxHD, h.264, MJPEG 2000, … ! audio codecs + parameters ! wrapper formats ! metadata: technical, application, user ! efficient integration in production environment 8
  8. 8. WP5 – SOA in Professional Media Production ! Goal: validate benefits of Service Oriented Architecture (SOA) and Business Process Management (BPM) in media production quot; modularity, agility, visibility ! Proof of concept: ! Processes automated in a BPMS with software services in an SOA ! Includes media-specific services ! Human interaction in the automated processes ! Both an IBM stack and an open-source stack Specific challenges: - Workflow deployment with optimal resource usage - Transfer management 9
