work on old mpeg standards
Work on "old" MPEG Standards
  • MPEG-4 Visual Simple Profile @ Level 6
    • Disposition of Comments on ISO/IEC 14496-2:2004/PDAM4 (N8948)
    • Text of ISO/IEC 14496-2:2004/FPDAM4 Simple Profile Level 6 (N8949)
    • Disposition of Comments on ISO/IEC 14496-4:2004/PDAM28 (N8952)
    • Text of ISO/IEC 14496-4:2004/FPDAM28 Visual Simple Profile Level 6 Conformance Testing (N8953)
  • Corrigenda on Conformance
    • Text of ISO/IEC 14496-4:2004/DCOR4 (N8950)
    • Text of ISO/IEC 14496-4:2004/Amd.1/DCOR2 (N8951)

  • Software and Conformance testing to most of our standards is publicly available
  • Currently, this does not apply for
    • 14496-7 (optimized reference software for MPEG-4 video)
    • Any component of MPEG-C
  • Video has issued resolutions recommending to change this situation
23002 1 idct precision
23002-1 IDCT Precision
  • Improved version of IDCT precision testing software and its description
    • Now includes the testbeds that were developed for checking IDCT conformance in MPEG-2 and MPEG-4 Visual video codecs
  • Disposition of Comments on ISO/IEC 23002-1/PDAM1 (N8980)
  • Text of ISO/IEC 23002-1/FPDAM1 Software for Integer IDCT Accuracy Testing (N8981)
23002 2 fixed point dct idct
23002-2 Fixed-Point DCT/IDCT
  • Disposition of Comments on ISO/IEC CD 23002-2 (N8982)
  • Text of ISO/IEC FCD 23002-2 Fixed-point Implementation of 8x8 IDCT and DCT (N8983)
    • Contains improvement of previous algorithm (LLM11 based), virtually same accuracy
      • complexity reduced by 2 shift operations
      • row-order transform first (as applied by many transform implementations in the market)
    • Software implementation will be included in the standard
23002 3 auxiliary video data representation
23002-3 Auxiliary Video Data Representation
  • Disposition of Comments on ISO/IEC CD 23002-3 (N8767)
  • ISO/IEC FDIS 23002-3 Representation of Auxiliary Video Streams and Supplemental Information (N8768)
    • Support for simple stereoscopic application, easily extensible to other application cases
    • Various editorial improvements
    • Request change of title

reconfigurable video coding1
Reconfigurable Video Coding
  • Work plan for development of toolbox is behind original (very ambitious) schedule
  • Definition of parsing and bitstream description need more investigation in CE
    • Work plan for 23001-4 CD and 23004-2 CD delayed by one meeting
  • Marco will report more technical detail
  • Good news: Work on conformance testing has been started
reconfigurable video coding2
Reconfigurable Video Coding
  • 23001-4 project description updated, mentioning support of non-MPEG toolboxes and intent to define a registration mechanism
  • Successful exploration experiment on first investigation to run RVC concept combining 23001-4 with non-MPEG toolbox (AVS)
    • Original AVS specification and reference software were now made available by AVS liaison – many thanks
    • EE can now be continued as real proof-check
    • Participation and contributions of AVS liaison members highly welcome
reconfigurable video coding3
Reconfigurable Video Coding
  • WD 4 of ISO/IEC 23001-4(N8979)
  • WD 4 of ISO/IEC 23002-4 (N8984)
  • Description of Core Experiments in RVC (N8985)
    • CE1: Decoder Description Language
    • CE2: Abstract FU description
  • RVC Simulation Model (RSM) V4.0 (N8986)
  • RVC Work Plan (N8987)
  • RVC Conformance Testing Working Draft 1.0 (N8988)
  • Description of Exploration Experiments for Toolbox Extensions (N8989)
