JVT Wednesday Report Bangkok JVTJVT JVT Report Wednesday Plenary 75 th MPEG Meeting, Bangkok Co-Chairs: Gary Sullivan, Jens-Rainer Ohm Vice Chairs: Ajay Luthra (absent), Thomas Wiegand ~110 attendants so far

JVT Wednesday Report Bangkok JVTJVT 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 :200x /PDAM2 (=JVT Joint Draft Ver. 2) –Joint 4:4:4 Video Model (JFVM) Version 2 –JFVM Software Version 2

JVT Wednesday Report Bangkok JVTJVT 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

JVT Wednesday Report Bangkok JVTJVT 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

JVT Wednesday Report Bangkok JVTJVT 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

JVT Wednesday Report Bangkok JVTJVT 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

JVT Wednesday Report Bangkok JVTJVT SVC – To Do and Finalize Produce Output documents (probably with editing period) –ISO/IEC :200x /PDAM3 (=JVT Joint Draft Ver. 5) –Joint Scalable Video Model (JSVM) Version 5 –JSVM Software Version 5
