JVET-L0008 JVET AHG report: 360° video coding tools and test conditions (AHG8) [J. Boyce, K. Choi, P. Hanhart, J.-L. Lin]

This document summarizes the activity of AHG8: 360º video coding tools and test conditions between the between the 11th meeting in Ljubljana, SI (10–18 July 2018) and the 12th meeting in Macao, CN (3 – 12 Oct 2018).

There was no AHG email activity on the main JVET reflector, jvet@lists.rwth-aachen.de, with an [AHG8] indication on message headers.

There is one non-CE related contribution related to 360º video coding, which is listed below. In addition, CE13 on projection formats is related to 360º video coding, and has 21 contributions, which will be described in the CE report in JVET-L0033. There are 4 additional CE13-related contribution, listed below.

• CE13 contributions (21 contributions, not listed here; see the section on CE13)
• 360 video contributions not related to CE13
  • JVET-L0238 AHG8: Chroma sample location type support for 360Lib [P. Hanhart, Y. He, Y. Ye (InterDigital)]
• CE13-related contributions
  • JVET-L0166 CE13-related: Subjective Quality Improvement for RSP [A. Singh (Samsung)]
  • JVET-L0212 CE13-related: Results for experiments as CE13.3.2, CE13.4.3 and CE13.7.7 with PHEC and impact of rotation on the coding performance of PHEC [J. Sauer, M. Bläser (RWTH Aachen University)]
  • JVET-L0237 CE13-related: Adaptive frame packing using chroma sample location type 1 [P. Hanhart, Y. He, Y. Ye (InterDigital)]
  • JVET-L0423 CE13-related: HEC with in-loop filters using spherical neighbours [Xuchang Huangfu, Yule Sun, Lu Yu (Zhejiang Univ.)

The AHG recommends the following:

• Review input contributions
• Conduct informal subjective viewing of contributions
• Review common test conditions for 360° video, including objective metrics and viewports
• Review 360° video test material, and consider adding or replacing test sequences for common test conditions
