Meeting Notes
JVET-H0004 JVET AHG report: Test material (AHG4) [T. Suzuki, V. Baroncini, J. Chen, J. Boyce, A. Norkin]

The test sequences used for the CfP (JVET-G1002) are available on ftp://jvet@ftp.ient.rwth-aachen.de in directory “/jvet-cfp” (accredited members and potential CfP respondents may contact the JCT-VC chairs for login information).

HM/JEM anchors (defined in JVET-G1002) were generated and verified by at least one cross checker.

HM anchors:

ftp://jvet@ftp.ient.rwth-aachen.de/jvet-cfp/anchors-hm

JEM anchors:

ftp://jvet@ftp.ient.rwth-aachen.de/jvet-cfp/anchors-jem

Relevant contributions to this meeting were noted as follows. (Most of the contributions are submitted for AHG7 and 8)

  • CfP anchor generation
    • JVET-H0060 “AHG4: SDR anchor generation for the Draft Joint Call for Proposals", H.-C. Chuang, J. Chen, M. Karczewicz (Qualcomm), K. Choi, E. Alshina (Samsung).
    • JVET-H0068 “AHG7: HLG rate points for CfP anchor generation", S. Iwamura, S. Nemoto, A. Ichigaya(NHK).
  • New test materials
    • JVET-H0021 “AHG8: Test Sequences for Spherical Video Coding from GoPro", Adeel Abbas (GoPro).
    • JVET-H0022 “AHG8: New Sequences for Virtual Reality Video Coding from InterDigital", Y. He, P. Hanhart, E. Asbun, Y. He, Y. Ye.
  • Study of the current test materials
    • JVET-H0038 “AHG7: Test Sequences of 4K Hybrid Log-Gamma", T. Tsukuba, M. Ikeda, T. Suzuki (Sony).
    • JVET-H0048 “AhG8: Dynamic viewport based subjective evaluation of Balboa and Landing", P. Hanhart, Y. He, Y. Ye (InterDigital).
    • JVET-H0068 “AHG7: HLG rate points for CfP anchor generation”, S. Iwamura, S. Nemoto, A. Ichigaya (NHK).
    • JVET-H0083 “AHG7: Cross-check of test sequences of 4K Hybrid Log-Gamma transfer characteristics (JVET-H0038)”, S. Nemoto, S. Iwamura, A. Ichigaya (NHK).
  • New BD-rate/PSNR calculation
    • JVET-H0030 “BD-Rate/BD-PSNR Excel extensions”, A.M. Tourapis, D. Singer, Y. Su, K. Mammou (Apple Inc.).

The AHG recommended:

  • To review all related contributions.
  • To evaluate visual quality of HM/JEM anchors.
  • To discuss further actions to select new test materials, and to revise the current test materials for CfP and to discuss the test conditions of objective quality evaluation for CfP.

In the discussion, it was noted that for the CfP we need to finalize the selection of the test sequences and anchors (including bit rates and objective-only testing sequences and conditions). For cases where candidate anchor encodings are already available, it may be better to use those than to delay availability of anchors in order to use a more recent JEM or HM version.
