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 • 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 • 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 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 • 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 • 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 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 • MV over pic boundaries restriction • Logo insertions and overlays • Fast motion estimation • Random access decoder functionality • Software and conformance • Future corrigenda (Not yet reviewed) Note: Basing amendment work on 2005 edition (not yet published)
