1. VQEG Joint Effort Group Berlin meeting A. Bourret- K. Brunnström P. Le Callet

2. JEG summary First scope: Hybrid NR-H264 o Profile:  At least : Stream at NAL level  Possibility to define extended profile to cover protocol level parameters (UDP, RTP, DVB, bluray …) o Level: from QCIF to HD Main goals and benefits o Joint Effort based on scientific exchange o no needs for secret database !  Common Working Dataset WD (known by contributors) to test the contributions  Possibility to present analysis based on non public dataset Goal : identify limits of contribution for further improvement  Possibility to constantly feed the database with new conditions …we can work on the database in parallel with model development Interested groups so far: o Acreo, NTIA, Ghent, Opticom, Ericsson, Tlabs, Intel, Verizon, BT, NTT

3. Progress First Call for evidence and contributions released http://www.its.bldrdoc.gov/vqeg/call_for_pape/VQEG_JEG_NR_hybrid_H264%20ver%203.pdf Objectives of the call This meeting will initiate JEG NR hybrid H264 activities through technical presentation followed by technical discussions sessions. Topics of technical presentation should cover: o Models: architecture for NR hybrid model, approaches and results o Software: PVS generation, bitstream analyser, objective metric tools (parametric, or perceptual) o QA results o Quality assessment methodologies and set up o Use case scenarios of NR hybrid QA metrics o Source material (reference videos): creation and existing materials The following technical discussion session will cover: metric framework, software integration and subjective QA campaign.
