JVET common test conditions and evaluation procedures for 360° video
Authors: Elena Alshina Jill Boyce Adeel Abbas Y. Ye
Abstract
This document defines common test conditions and software reference configurations to be used in video codec performance evaluation for 360° video. These 360° video test conditions are also recommended for use in technical contributions to the 7th JVET meeting.

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 tools, and how to ease the assessment of single tools in terms of encoder runtime.
  • Study and summarize new technology proposals.

JEM algorithm description editing (AHG2)

(jvet@lists.rwth-aachen.de)

  • Produce and finalize JVET-F1001 Algorithm Description of Joint Exploration Test Model 6.
  • 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.

JEM software development (AHG3)

(jvet@lists.rwth-aachen.de)

  • Coordinate development of the JEM6.0 software packages and their distribution.
  • Produce documentation of software usage for distribution with the software.
  • Prepare and deliver JEM6.0 software version and the reference configuration encodings according to JVET-B1010 common conditions.
  • Coordinate with AHG on JEM model editing and errata reporting to identify any mismatches between software and text, and make further updates to the software as appropriate.
  • Investigate the implementation of SCC coding tools in JEM.
  • Coordinate with AHG6 for integration of 360° video...

Meeting Notes
JVET-F0007 JVET AHG report: JEM coding of HDR/WCG material (AHG7) [A. Segall (chair), E. Francois, D. Rusanovskyy (vice chairs)]

The document summarized activities related to the AHG on JEM coding of HDR/WCG material between the 5th and the 6th JVET meetings.

Activities related to the mandates of this AHG include

  • Sequences generated with the recommended conversion practices decided at the previous meeting were generated and released for study. The sequences were made available at:

ftp://ftp.ient.rwth-aachen.de/testsequences/testset_hdr/

  • Candidate software integrating the HDR/WCG specific tools required for the anchor defined in JVET-E1020 was released for study. The software included support for luma and chroma adaptive quantization parameters. The software was made available at:

https://jvet.hhi.fraunhofer.de/svn/svn_HMJEMSoftware/branches/candidates/HM-16.6-JEM-5.0.1-AHG7-Anchor/

  • Anchors for the Call for Evidence HDR test were created and cross-checked. The results were reported to the reflector on March 20, 2017.
  • Anchors for the Common Test Conditions were created and cross-checked. (Note that this was side activity and not officially reported to JVET at the time of this report.)

During the generation of the CfE anchors, the following observations were reported to the AhG. It is suggested to further discuss these during the 6th meeting in combination with related input documents.

  • It was commented that during anchor production and visual assessment of the results that the bit rates for the HDR3 (EBU_05_Hurdles) and HDR4 (EBU_06_Starting) test sequences may be swapped.
