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

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. 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
