JVT ReportWednesday Plenary75th MPEG Meeting,
Bangkok

• Co-Chairs Gary Sullivan, Jens-Rainer Ohm
• Vice Chairs Ajay Luthra (absent), Thomas Wiegand
• 110 attendants so far

2
Advanced 444 Profiles

• Contribution areas
• Separate vs. common prediction modes
• Residual color transforms
• Improved lossless inter coding MB mode
• Produce Output documents (probably with editing
  period)
• ISO/IEC 14496-10200x /PDAM2(JVT Joint Draft
  Ver. 2)
• Joint 444 Video Model (JFVM) Version 2
• JFVM Software Version 2

3
Scalable Video Coding

• Reviewed input documents related to topics of
  Core experiments
• CAVLC Non-negligible compression improvements
  shown, possible complexity reduction
• Inter-layer motion prediction Moderate
  compression improvements for some sequences
• Inter-layer texture prediction Significant gain,
  definition of filter adaptation to be considered,
  smoothed reference prediction makes better use of
  base layer residual information
• Quantization Further encoder optimization
  adopted, quantizer offset adaptation to be
  further considered

4
Scalable Video Coding

• Reviewed input documents related to high-level
  syntax
• solutions regarding various issues related to
  buffer management, signaling of scalability etc.
• Discussed file format items jointly with systems
  experts
• same exercise still to be done w.r.t. MPEG-2
  carriage

5
SVC JSVM Software

• JSVM 4.0 Software had not been finalized bug-free
  in the given time schedule
• this had slowed down some of the core experiments
• Breakout group of experts
• has resolved a number of bug fixes
• has made a proposal for improving the situation
  by setting up automatic testing procedures
• In the future, more rigid procedures will be
  implemented if software of accepted proposals is
  not delivered in time and bug-free

6
SVC To Do and Finalize

• Review remaining technical/CE inputs on
• ROI
• Improved and low-delay FGS
• Interlaced
• SNR scalability
• Error resilience
• Encoder optimization
• Core Experiments
• t.b.d. which previous experiments to continue

SVC To Do and Finalize

• Produce Output documents (probably with editing
