Jeg summary

JEG summary

  • First scope: Hybrid NR-H264

    • Profile:

      • At least : Stream at NAL level

      • Possibility to define extended profile to cover protocol level parameters (UDP, RTP, DVB, bluray …)

    • Level: from QCIF to HD

  • Main goals and benefits

    • Joint Effort based on scientific exchange

    • 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:

    • Acreo, NTIA, Ghent, Opticom, Ericsson, Tlabs, Intel, Verizon, BT, NTT

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:

Models: architecture for NR hybrid model, approaches and results

Software: PVS generation, bitstream analyser, objective metric tools (parametric, or perceptual)

QA results

Quality assessment methodologies and set up

Use case scenarios of NR hybrid QA metrics

Source material (reference videos): creation and existing materials

The following technical discussion session will cover: metric framework,  software integration and subjective QA campaign.
