JVT ReportWednesday Plenary75th MPEG Meeting, Bangkok

Co-Chairs: Gary Sullivan, Jens-Rainer Ohm

Vice Chairs: Ajay Luthra (absent), Thomas Wiegand

~110 attendants so far

advanced 4 4 4 profiles
Advanced 4:4:4 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 14496-10:200x /PDAM2(=JVT Joint Draft Ver. 2)
    • Joint 4:4:4 Video Model (JFVM) Version 2
    • JFVM Software Version 2
scalable video coding
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
scalable video coding1
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
svc jsvm software
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
svc to do and finalize
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 finalize1
SVC – To Do and Finalize
  • Produce Output documents (probably with editing period)
    • ISO/IEC 14496-10:200x /PDAM3(=JVT Joint Draft Ver. 5)
    • Joint Scalable Video Model (JSVM) Version 5
    • JSVM Software Version 5
remaining jvt topics
Remaining JVT Topics
  • MV over pic boundaries restriction
  • Logo insertions and overlays
  • Fast motion estimation
  • Random access decoder functionality
  • Software and conformance
  • Future corrigenda
