Description of Exploration Experiments on Coding Tools
Authors: Elena Alshina Jill Boyce Y. J. Chang Seung Hwan Kim Vadim Seregin Xiaoyu Xiu
Abstract
Documents describes Exploration Experiments (EEs) planned to be performed between JVET-C and JVET-D meetings in order to get better understanding of technologies considered for inclusion to the next version of JEM, analyse and verify their performance, complexity and interaction with existing JEM tools.

JVET-C1011 Description of Exploration Experiments on coding tools [E. Alshina, J. Boyce, Y. J. Chang, S.-H. Kim, V. Seregin, X. Xiu] [2016-06-23]

See list of EEs in section 9.1

The version reviewed on Tuesday was again approved in the closing plenary on Wednesday. One minor change was made, adding Qualcomm as an additional contributing party in EE9 test 4.

Some affine MC friendly content should be made available, as allowed by content rights, so that it can be used in EE4 tests. X. Ma (Huawei) was requested to contact Mathias Wien to enable uploading of such content to the JVET content repository. Once content has been made available, this should be announced on the JVET reflector.

Tool evaluation (AHG1)

(jvet@lists.rwth-aachen.de)

  • Coordinate the exploration experiments.
  • Investigate interaction of tools in JEM and exploration experiment branches.
  • Discuss and evaluate methodologies and criteria to assess the benefit of tool, and how to ease the assessment of single tools in terms of encoder runtime.
  • Study and summarize new technology proposals.
  • Prepare visual quality comparison for HEVC and JEM at comparable bit rates.

JEM algorithm description editing (AHG2)

(jvet@lists.rwth-aachen.de)

  • Produce and finalize JVET-C1001 Algorithm Description of Joint Exploration Test Model 3
  • Gather and address comments for refinement of the document
  • Coordinate with the JEM software development AHG to address issues relating to mismatches between software and text.

Exploration Experiments on Coding Tools Report
Authors: Elena Alshina Jill Boyce Y.-W. Huang Seung Hwan Kim Li Zhang
Abstract
Seven experiments on coding tools were agreed to carry out between JVET-B and JVET-C meetings in order to get better understanding of technologies considered for inclusion to the next version of JEM, analyse and verify their performance, complexity and interaction with existing JEM tools. This report summarises the status of each experiment.
