  • Significant progress has been made in the past 60 days. Submission of work statement this week to SMPTE.
  • VSF is pursuing liaison with MPEG to determine time frame for MPEG activity, then a decision can be made on full MPEG or private data fields
  • Connect once, display everywhere Features Video, audio and metadata sources can be connected to NBMS at various physical places Autosensing inputs Encoded sources are sent where monitoring is needed The Display Generator only pick the required sources from the multicast network The desired Layout is composed on the BMS software Benefits Facility wide monitoring Logical connectivity instead physical connectivity Saving cables Adding flexibility Removing complexity Offering scalibility

  • JPEG2000 Alliance
    • Who
    • a consortium of technology leaders
    • Goal
    • JPEG2000 development into a leading compression standard
    • JPEG2000 widespread acceptance and deployment
    • How
    • educate and create awareness about the benefits of JPEG2000
    • support of the compression standard for the benefit of the media and video industries
    • promote interoperability between standards and system devices
    • promote the development of tools by members and industry peers
  • About JPEG2000
    • License free
    • Open standard
    • Lossy and lossless compression
    • Error Resilient
    • Precise and adjustable bit rate control
    • Scalable
    • Low latency
    • Constant quality through multiple generations
    • Supports 4K resolution (and greater)
    • Up to 32-bits per component
    • Symmetric encode and decode
  • Mathematically Lossless Compression
    • It enables a reduction in storage requirement of, on average, 1:2 while still being able to recover the exact original image information.
    • Extremely important feature in fields such as digital archiving, cinema acquisition and medical imaging.
    • Unique advantage in comparison to JPEG, MPEG2, MPEG4
  • Scalability
    • JPEG2000 is able to extract multiple versions out of a single compressed file
    • This scalability provides
      • Easy proxy generation
      • Region of Interest
      • Bandwidth optimization and adaptive transmission
  • Low Latency
    • Intra-frame allows every frame to be encoded independently allowing latency of less than 1 frame
    • In comparison, inter-frame encoding formats (e.g. MPEG2, MPEG4) need to work with Groups of Pictures (GOP) that require a longer processing time
    • Low latency is a critical consideration in many applications
  • Constant Quality Through Multiple Generations
    • Successive encoding-decoding passes are usually required throughout the Broadcast and Digital Cinema post-production processing chain
    • JPEG2000 provides a constant image quality throughout the production process

  • VSF JPEG2000 Activity Group
    • Mission
    • Create a recommendation for standardization of real time transport of JPEG2000 for Contribution over IP Networks
    • Real time service encapsulating JPEG2000 compressed video, audio, time codes & closed captioning in a program stream
    • Encapsulation into MPEG2TS and the IP/RTP structure for final transport
    • Utilize a single RTP stream for video/ audio/ancillary
    • CBR & VBR streams supported
    • Streams up to 1800Mbps supported
    • Two solutions/efforts:
    • MPEG2TS/SMPTE2022 initially thought to be faster to market and with backwards compatibility with legacy MPEG2TS equipment
      • Recommendation development is ongoing, must work with JPEG and MPEG to complete a standard
    • MXF Wrapping over RTP with RTP/Payload Header & FEC
      • VSF work for native uncompressed video should be usable for this effort
      • EBU will pursue this activity
  • Standardization
    • Liaison with JTC for Working Draft on Amendment 4 for 15444-1:2004, Profiles for Broadcast Applications
    • JPEG PES with header has been defined
    • MPEG working on JPEG2000 as PES
  • Standardization
    • Establish a liaison with MPEG in order to exchange information regarding work that MPEG is doing in Working Draft 1.0: Transport of ISO/IEC 15444-1/AMD4 on mapping of JPEG-2000 into MPEG-2 transport streams
    • Utilize the output of that work to complete VSF/SMPTE document development regarding transport of JPEG2000 over IP.
    • This work will ultimately create a JPEG2000 PES within a MPEG2TS
    • Transport will be robust over a wide range of network performance by application of IP encapsulation and FEC (SMPTE 2022- # FEC)

  • Multiple generation performance Degradation < 0.7 dB for 5 th generation Less than 1 LSB at 10 bits resolution
  • JPEG2000 as a Preservation Master
    • JPEG2000 is fast becoming the defacto standard for preservation quality content archiving
    • Media and entertainment companies have been slow to adopt but the opposite is true for archivists
    • Limited “interoperability” between typical broadcast devices and “large file sizes” are considered barriers True preservation presents different challenges than traditional file based operations in media organizations
  • Effective Content Migration Video/Film Masters Solo Migration Engine DIVArchive CSM Data Tape Lossless MXF Wrapped JPEG2000 MXF Wrapped IMX50 MPEG2I QT Wrapped DV25 High Resolution Frame Based Migration Metadata Windows Media MPEG4 AVC Flash Video Proxy Resolution Preservation Package
  • Storage Efficiencies
    • Archive Package average approx 180Mbps with all target essence formats (preservation, interoperable and proxy)
    • Formats can be added/removed depending on specific goals
    • A single LTO4 data tape provides:
      • 800GB of storage capacity
      • 10 hours of source content Archive Package storage
      • € 30 street price!
    • Many goals are simultaneously accomplished:
      • JPEG2000 for long term content preservation (LOSSLESS!)
      • MPEG2/DV for broadcast device interoperability
      • MPEG4/WM9/FLV/etc for proxy browsing/web/mobile

  • JPEG2000 vs. MPEG4/H.264 JPEG2000 MPEG4/H.264 Wavelet-based – no Blocking Artifacts DCT-based -- Blocking artifacts Symmetrical – Encode and decode are the same Asymmetrical – encoding is expensive
    • I-Frame only
      • Errors only affect one frame
      • Easy error concealment
      • Trick modes don’t change bit rate
    • I-frame and P-frame/B-frame
      • Errors affect entire GOP
      • Difficult to conceal errors
      • Trick modes increase bit rate
    JPEG2000 encoding is naturally tolerant of errors; errors only affect one frame Errors can affect entire GOP Low latency – Single Frame Complexity of compression results in higher latency
    • Precise and adjustable bit rate control
      • Can be adjusted on a frame-by-frame basis to adjust for varying conditions
    • No bit rate control
      • Can’t lower bit rate if necessary;
      • Trick modes raise the bitrate.
  • JPEG2000 is Ideal for Wireless Video JPEG 2000 H.264 MPEG2 MPEG4 Motion JPEG2000 for Wireless Applications, Dufaux and Ebrahimi, 2003 ** NOTE: Coding efficiency advantage of H.264 is for low bit rate coding and would result in decreased quality; higher quality high bit rate coding would not provide H.264 with a coding efficiency advantage Artifacts Error Resilience Complexity Scalability Latency Coding Efficiency**
