JVET-AM0018 JVET AHG report: Ultra-low latency and packet loss resilience (AHG18) [S. Ikonin, S. Wenger, V. Zakharchenko (co-chairs), S. Deshpande, S. Fößel, C. Kim, X. Ma, S. Puri, J. Ström (vice-chairs)]
Simulation software
Adoptions of the last JVET meeting (JVET-AL0201) were merged to the ‘ull-master’ branch: https://vcgit.hhi.fraunhofer.de/jvet-ahg-ull/VVCSoftware_VTM/-/tree/ull-master.
Teleconferences
Two teleconferences were held on May 20th and June 11h, with 24 and 17 participants correspondingly.
The following topics were discussed:
- GDR and Temporal scalability transmission simulations.
- Comments and suggestions on ULL test conditions
- Dry-run of visual tests discussion
- Software modifications of JVET-AL0201 adopted last JVET meeting
The meeting minutes, presented materials and video demonstrations are available in JVET-AM0046 and JVET-AM0051.

Recommendations
The AHG recommended:
- Review all input contributions.
- Discuss test conditions and evaluation methodology.
- Consider bypassing key important information over transmission channel as reasonable setup for dry-run subjective evaluation to avoid too much video stall
- Collect test cases and specific requirements.
- Continue development of simulation software.
- Continue the study of ultra-low latency and packet loss resilience technologies in JVET.
