JVET-M0017 JVET AHG report: High-level syntax (AHG17) [R. Sjöberg, S. Deshpande, M. M. Hannuksela, R. Skupin, Y.-K. Wang, S. Wenger]
This document summarized the activities of the AHG on High-level syntax (HLS) between the 12th JVET meeting in Macao, CN (3–12 Oct. 2018) and the 13th meeting in Marrakech, MA (9–18 Jan. 2019).
No e-mail related to AHG17 was sent to the JVET reflector during the AHG period except a kick-off message.
It was reported that the amount of input contributions related to the mandates of this AHG has increased from 8 in Macau to 22 for this meeting. For the wider category of high-level syntax contributions including AHG12, AHG14, AHG15 and AHG17, the number of input contributions is reported to have increased from 28 in Macau to 50 for this meeting. Note that the count differs from the JVET-M_Notes_d0.docx categorization in which 49 documents are allocated to section 6.19 “High-level syntax”.
It is reported that of the 12 JCT-VC meetings where the first version of HEVC was developed, the first 6 meetings had fewer high-level syntax contributions than this JVET meeting and the last 6 had a higher number with a peak of 96 of high-level syntax contributions at the 11th meeting in Stockholm 2012.
The number of documents in the high-level syntax category was noted to have increased from 8 to 50 in two meeting cycles.
22 of the input documents registered by January 7 were identified as related to the mandates of this AHG.

It was noted that at some point in the HEVC development, we started having AHG pre-meetings for HLS work.
The AHG recommended reviewing the related input contributions and to continue to study VVC high-level syntax aspects.
